    Evening all, I am so super excited I just had to post about it. My son and I are still learning how to use the scope properly, we have now managed to line up the red dot finder and are frequently able to view Jupiter and Saturn. We have been trying to take a photo of them (with just a smart phone as funds wont stretch to a camera at the moment), well tonight we have taken this beauty of Jupiter and her 4 moons. I know it is a bit zoomed out but we are working on how to get a closer shot. What do you think? Jo

    Well, not an observatory as such, more an observing area. A ROR or a dome were both non starters as our garden is quite small and a housing to accommodate a refractor 79" long, with room for me as well, would be too big. My wife was almost willing to accept the ROR, but I decided not to ' push it ', and created this area instead. The trellis, viewed from the Conservatory will fairly quickly be covered in the Passion Flower and Clematis both of which are growing vigorously. I bought some canvas type material and hung it on the inside to shield light from my house and from my neighbour's security light, which seems to be on more frequently now, sometimes all night. It all works very well, no light visible and is actually quite cosy, not to mention fragrant from the various planting. I now have power to the pier, and everything except the telescope is covered over with the..er..cover. I just need a plastic box in there to store the curtains during the day. The corner table for my eyepiece box, I cut from a kitchen worktop thrown out six years ago. I rarely recycle anything deemed 'possibly useful '. It takes just a minute to carry the 5" from conservatory and locate it on the mount in the correct position, flick the switch, and away, so I am pretty happy really.

    Lunar early last night. Conditions started out as average to good but slipped away to poor just before clouds rolled in. Visual observations of the lunar surface were quite nice, heaps of craters to explore with good detail. This image is a 2 stacked image stitch. Location Mandurah Western Australia.

    Later it just got enjoyably better with a slight Milky Way at the zenith. A check showed sqm of 19.47, ace for the edge of town. Spent most of the time on Cassiopeia, enjoying the open clusters here . Went for a few lesser known King and Cr clusters. Of these King 12, King 21 , Cr 463 and Cr 36 stood out from the field of stars. Pleased to attach details below, makes a change from the norm ! Into Lacerta and the spectacular sparkling NGC 7209 and NGC 7243. Then a horizontal view , laying down to look at the views overhead and that theatre of Wonder from Cassiopeia to the front of Pegasus. Over to Perseus and the lovely triple Σ 162 (SAO 37536) . A great view of Σ 314 (SAO 23674) showing lovely twins 1.5" apart. Always a wonder to get an insignificant star then observe at high magnification. A brilliant challenge is ψ Cassiopeiae (SAO 11751), tease out the companion to give a triple group. Iota Cass. gave a great view. Pleased to attach a few bits of Cassiopeia. A wonderful calm, dry and warm few hours, under , Clear skies ! Nick.

    We were treated to an excellent storm on the last night of our trip to northern Italy, just outside Milan. The view was nice from the 5th floor balcony and the rain never reached us. I got a few shots with my D800E and a Nikon 180mm F2.8 lens 5-10s exposures at F5.6 ISO400. Then a few wide fields with my Tokina 28-70mm F2.8 lens, 20s exposures, made into a composite image. I made a couple of timelapses too. I hope you enjoy them, as much as I enjoyed the whole experience. CS Adam

    Got back in the saddle with a high familiar target. Loads of issues from non-use, and an extremely lucky escape when a heavy shower of rain bowled through when i had fallen asleep and soaked everything (happily I got away with just losing a usb hub). This is a cropped stack from 48 x 7 minutes Ha (1x1) and 70 x 7 minutes O111 (1x1) plus 20 x 7 minutes O111 (2x2) as the 1x1 O111 was weak; 7 minutes is as long as I can avoid guiding (but that's another issue) and arguably i have pushed it too far anyway. I have some rgb but it is terrible. Cropped to remove edges from different evenings etc

    As a noob with a bit of an eBay habit my eyepiece collection has grown a bit out of hand Initially happy with the 25mm/15mm/3x Barlow that came with the Tal-1 I first purchased, a bit of cut foam sufficed but now I have more and I absolutely need to take them all out with me just in case So I made this insert and am chuffed with it Will need another case soon for the couple of 2” wide angle eps I also bought though...

    A raw, uncalibrated light frame, no calibration, no cooling, just a stretched 120 second sub. Quite pleased for a very first effort. G2-8300 Moravian camera with 3nm HA Astrodon filter with Samyang 135mm at F2, unguided at this stage. All on a NEQ6 mount. I have lots to do on this rig to get it properly set up. Least of all getting EQmod to work with SGP for which I will fire up a new thread.

    Laurin Dave and I shot two panels of luminance (18x15 minutes each) and an hour per colour per panel. I already had a deep OIII and Ha set 'in stock' and an RGB layer of an hour per colour per panel so we put them all together. In my existing HaOIIIRGB version I think I pushed too hard, trying to get narrowband depth in a natural colour image. It was never a very happy image. In this processing I decided to settle for less depth in the faint stuff and a more natural look. The brown dust on the right hand side is, we both feel, genuine. I've seen it every time I've shot colour on the Veil and the star count is also lower against the browns, consistent with the presence obscuring dust. Perhaps this dust is even being compressed by the expanding shock wave creating the Broom? I actually lowered the saturation of the browns in this version. Total exposure over 30 hours. Tak FSQ106N/Mesu 200/Atik 11000 mono. There is neither noise reduction nor sharpening in this one. Data calibrated using master bias, bad pixel map and luminance flat for all filters.

    Hello to u all from "Hoth". I see its customary here to introduce yourself as a new member so here I am. I am pretty much a rookie when it comes to this hobby. I have had a lot of things going on over the years. I am a security / network equipment tech by trade, and what claims most of my time off is the work I do as a musician. The night sky always fascinated me tho. When I was a kid I used to put up a ladder onto the garage roof where I lived and lay back and watch the sky for hours. As for instruments to actually use for this, I always saw as unobtanium. However... In my early 30s one time i had some cash to spare, almost on impulse, I bought a skywatcher refractor. Dont remember the model, but it's a 70mm lens and about half a meter long. I got it in the mail, and it lived in the trunk of my van for some days until I one day took it to my office. Hehe - I didnt want to tell the missus I had spent money on a telescope. Haha so it sat in my office for a month or so before I brought it home and thought- she will understand. I brought it into the living room and asked her if she liked my telescope. I explained - it was not spendy and I always wanted one and figured now was a good time to get one. She wasnt overly enthusiastic about it - because she didn't see the value in it. But as time went by I took my oldest kid outside an evening with a full moon. He was amazed and frankly so was I. I shot some pictures of the moon just pointing the phone cam to the eyepiece. Showed it to her and she was also amazed. I was hooked instantly. So I set the scope up in our living room. After standing there at a window for a couple of days, the missus asks me - Is that one gonna stay there now? A simply - yes of course- was the answer, and here I am. Been watching YouTube videos to learn this, but I miss a real community, and found this place on pure chance. First thread I read coming from google was about some guys here discussing some eyepiece question asked on CN and after reading that I decided - no way I'm going there, I'm staying here - looks like it's a bunch of good guys here and I like the fact that its kept family friendly! I'm sorry for the lengthy introduction, but I thought I'd do it the proper way hehe. Any questions, feel free to ask. See you around

    Over the summer I have been acquiring data for various globular clusters. I already posted M92 back in June and here are three more completed images for you to compare and contrast: M12 16,000 light years away in Ophiucus M56 32,000 light years away in Lyra M71 13,000 light years away in Sagitta M12 & M56 have one hour in each of R,G & B and M71 has two hours in each channel. I have combined all subs to make a 'SuperLuminance' layer in each image - I find that this works pretty well to maximise the data and improve clarity a bit. All were captured through a Celestron EdgeHD 8" on a Mesu 200 mount, with a QSI 683-WSG8 & 31mm Astrodon filters. Processed with APP and PS CC. Some say that all Globular Clusters look the same, but I hope this selection goes some way to changing your views on that! Most noticable is the difference in the star fields between the three images, starting on the edge of the plane of the Milky Way with M12, getting closer with M56 and right in there with M71. M71 is also known as The Angelfish Cluster - can you see him... swimming up to the left towards about 10 o'clock?! I look forward to hearing what you think and in the meantime... clear skies!

    I think eyepieces are well down the list of things that could be restricting the quality of your planetary views to be honest with you. Your Baader Classic Ortho 10mm will probanbly be delivering as good a view of Jupiter and Saturn as the scope and conditions will allow. Have a look at this article from an experienced observer and especially the section called "The Wobbly Stack": http://www.scopeviews.co.uk/Eyepieces for Planets.htm Note how far down the list of factors the eyepiece is.

    When it comes to observing Jupiter and Saturn, I don't enjoy an exit pupil any lower than about 0.6mm. At this stage the image of the planets is already quite dim for me and floaters are drifting more often in front of detail. As such, 0.6mm is a working limit on these two gas giants. However, I've also found that 25x - 40x per inch of aperture is a decent general guide for maximum magnification for me when viewing Jupiter and Saturn. I know folk observe the two gas giants over this limit but not all my scopes can handle this and just as importantly floaters are becoming ever more apparent and the atmospheric conditions where I live generally don't support higher per inch magnifications. Along this lines, I've found that seeing - atmospheric turbulence - starts to raise its ugly head from about 100x and really starts to interfere with my observations from around 180x to 200x. Unless I have very steady skies I can rarely observe Jupiter and Saturn over these higher magnifications. Finally, I also need to take into account things like the scopes collimation, cooling, my own fatigue and so on. So, as you'll appreciate, when it comes to observing Jupiter and Saturn there's a little bit of compromising going on: a) the quality of my eyes b) the quality of my optics c) the quality of the seeing and d) the 3 Cs: quality of collimation, cooling and personal conditions. If we take these ideas and apply them to you 6" f5 reflector, I think we can come to some conservative estimates. 25x per inch represents an exit pupil of 1mm. In your own case, you'll get about 150x with a 5mm eyepiece. This 150x, 1mm exit pupil I'd set for the moment as a high power for your 6". This doesn't mean you can't go higher. Of course you can, but exit pupil will become tighter perhaps giving rise to floaters, it'll cause further dimming of the object and decent seeing conditions will be more limited as you push the magnification. I feel this is good news, for you already have a 10mm eyepiece and a x2 Barlow, so you really don't need to spend the money . So much depends on atmospheric conditions when it comes to magnification and planetary observation. Perfect conditions are rare, especially this season with Jupiter and Saturn being so low. Personally, then, I'd sit it out. I'd advise you to not spend your cash on a lower exit pupil eyepiece and instead limit yourself to this 150x for this season with Jupiter and Saturn and see where you are in terms of scope, experience and disposition next year. Other than that, it might be an idea to invest in a decent zoom and overtime you'll be able to work out what maginifications work with your scope, skies and eye and of course perhaps the most important factor, to just sit calmly with the planets, spend some time at the eyepiece with them and let the seeing, turbulence and your own dispositions make the features more then less then more observable. I also think its a good idea from time to ime to sketch what we are observing. I feel this also strengthens observing skills.

    Thanks, good link. I don't think it's Ha because it doesn't show in that data. If you look at the upper tip of the Witch's Broom and imagine a line going from there to the top right hand corner you can see that, to the left of that line there is a high star count and, to right of it, a much lower one. My guess is that the shock front of the broom actually still exists along that line so the region to the left is more transparent, having been swept. Olly Edit, here's an Ha-OIII monochrome rendition.

    Thank you all for your input and recommendations - and I thought imaging was confusing!! So, I have plumped for the 28mm and 16mm ES68's for now. You have all given me food for thought as and when I expand and acquire the dob. I think in the coming season I will make a nuisance of myself at the SPs and start taking more of an interest in the eyepieces being used! I'll report back on how I get on with them, but really, thanks everyone!

    Been watching this with interest as I have a C8 edge and have the same problems with living in built up area surrounded by neighbours hot roofs. Seeing is always naff, planet jumps around and wobbles during capture. Here's one I managed with the same scope on the 2nd so don't give up. From memory it was a 2 minute avi around 0.7 secs and 300 gain ( ZWO 224mc) and a 2 X barlow
  32. 3 points
    I don't think that's the fault of the C8. For a start, it isn't debayered - it's actually a colour image: The blue at the top and red at the bottom shows the need for an atmospheric dispersion corrector at the moment - you will lose all fine detail otherwise. The colour balance is way off as well, unsurprising as it hadn't been debayered: I think the focus is poor - try focusing on a relatively nearby star, Altair at a push. I think this is a single frame? The hot pixel suggests it is, if so it's possibly a bit over-exposed as well. Finally, I would aim for 5,000 frames with as short an exposure as you can get away with - use maximum gain and rely on stacking 500-2000 frames to get rid of the noise. Don't give up of the C8, but if you want to swap it for my 150PL... this is what I've got this year, the C8 ought to be able to beat this.

    Great stuff Jo. You've both done a great job with focus and the moons are nice and tight, no wobbling there! Things to try are to control the exposure better to show up some surface detail on the planet. You will likely loose the moons but there is not much you can do about that. Do have a look in the Smartphone/tablet section of the imaging forum as there is plenty of help and advice in there. There is also a long thread called 'StuPOD' or similar, basically Stu's Picture Of the Day for smartphones which started out rather tongue in cheek but has lots of good and bad examples of smartphone images. https://stargazerslounge.com/forum/279-imaging-smartphone-tablets/ I took this one of Saturn with a smartphone recently, not great but recognisable. Also attached is my best ever Jupiter which shows what cam be achieved, although Jupiter was higher then and I haven't achieved similar results this year. Depending on what sort of phone you have, there are various apps which help with capture and processing. Nightcap and Procam 5 are good ones for capture, Snapseed and PS Express work well for processing on your phone. Have fun out there Stu

    Really had poor conditions for imaging this last vacation, first in the Alsace, then in Normandy, but on the last day the moon popped up, and I rattled off 48 shots with the Canon EOS 80D and 100-400 mm F/4.5-5.6 L IS zoom. Stacked 1600x1600 crops of 36 of them in AS!3 and postprocessed with FitsWork4. Not too shabby for a simple hand-held shot

    A popular object at the moment and derservingly so. There is a slot between a beast of a tree and my neighbours house that allows about an hour of imaging of this iconic object. I was keen and the Moon with scudding cloud kept out of the way. So 23x1min Ha and 11 x 2mins O3 with an Atik 414ex mono @-20'C attached to an UK Orion Optics Mak140 ( Astrophysics 0.67x reducer). This is the intial DSS stretch and a bit of tweaking in PS. No refinement to be seen here !! I'm quite pleased with that. Sean.

    I’ve just returned from a “summer holiday preview” long-weekend trip to our place in SW Ireland. No family, no cats, just my astronomical toys and me. And with luck, some clear nights. Luck was with me. I flew into Cork airport on a heavily-delayed flight late on Wednesday night, collected my little hire car and drove for 90 minutes or so. Arcturus was my lodestar, constantly in my vision as I drove West. The contrast between driving in SW Ireland and the outskirts of London is sharp: there were fully 10-mile stretches on the main-road N71 where I didn’t see a single other vehicle. To be sure, it was the early hours but even so. I arrived at 0234, stepped out of the car and gasped. I’d deliberately looked up when collecting my car at Cork airport, and the difference in sky blew me away, as it always does: the Milky Way bright through the zenith, most of the asterisms lost in the mass of stars. It was too late of course to set anything up, so I spent an hour or so with my binoculars (Nikon 12x50), whetting the appetite for the following night, Thursday, which was also forecast clear. I finally crept into my pit at 0400. I have two telescopes that permanently live in Ireland, a 12” Skywatcher Newtonian and a Mak 180 together with the AZ-EQ6 and Berlebach Planet. My eyepieces came in my luggage, along with a Lacerta dual-speed upgrade kit (thanks @niallk – an old post of yours inspired me to that) for the single-speed focusser on the Newt, my APM 50mm finder, 2 pairs of binoculars, a DSLR with 300mm and 24mm lenses, a laptop, a set of craftsman’s screwdrivers (Facom 6-piece kit – superb) and the TS-Optic SCT focusser that nobody on this forum seems to want to buy off me. I’d stretched the hand-luggage allowance to the very limit and needless to say, my bag was set aside and inspected. Thursday 1st August 2019 In keen anticipation of the clear night I spent the lovely sunny Thursday afternoon, when not swatting away Painted Lady butterflies, setting up and lining up: Mount in AZ mode , 12” Newt on the main saddle, Kowa 88mm spotting scope with 20-60x zoom on the other side. APM 50mm RACI plus RDF on top of the Newt. From my patio, I have direct line of sight to the radar domes atop Mount Gabriel 20km distant, so getting everything lined up was easy. Also, I noticed that the 12” Newt needed no re-collimation from the last time I’d used it 4 months ago! I’d prepared a list, but didn’t entirely stick to it. It included M31, M57 ring, M51, M63 sunflower, M13/92/3/53 all globulars, M64 black eye, M81/82, M106. The night didn’t disappoint. My SQM-L gave me 21.5, not too bad but not like the 22.0 I had here at Easter, and the Milky Way was more or less directly overhead. My list was a mix of galaxies and globular clusters, with one planetary nebula, but I was really looking forward to the globs: these seem to be my “thing” at the moment when it’s dark enough. M13: I started with Great Hercules Cluster. My goodness, what a beauty (again). From this dark location, I’ve probably spent more time on this object than any other. I returned to it time and time again between other targets. And I finally actually “saw” the propeller. It really felt 3-dimensional, as though I was inside its outer limit. Also, with the rig I had that night, the progression from naked eye to 8x50 finder to 88mm birding-scope 60x to the 12” was really rewarding. Naked eye, it’s a “not-a-star” hazy blob. With the APM 8x50, it’s a less indistinct version of the same. Through the Kowa 88mm at 60x, it’s clearly got some structure and you can see it’s an aggregation of stars with distinct brighter ones away from the centre. But it still doesn’t prepare you for the view through the 12”. I also hopped across for a quick look at M13’s little companion, NGC 6207, which was readily visible. I took a picture of M13 a year or so ago and NGC 6207 and featured in that, but this is the first time I’ve actually observed it. M13 is the object I shall use to shock and amaze newcomers with just such an aperturical progression from meh to amazing. Most layfolk have simply never heard of a globular cluster. M92, M3, M53: these were all similarly beautiful, but I was obsessed with discerning the Propeller in M13 so I didn’t give these others the time they deserved. Plenty of time for that I hope. M57: the Ring Nebula. Again, the difference between 88mm (3.5”) of aperture and 305mm was interesting, but 60x magnification wasn’t really enough in the Kowa for a proper comparison. A bright polo which I spent a while staring at. M81/82: a quick look, just to tick off the list. The diagonal slash in M82 was quite evident. M51: two rather bright cores and some evidence of more structure. Early Perseid: in between all the Messier objects, as I was looking North-Eastish, I saw what must have been an early Perseid, quite the most spectacular meteor I have ever seen. It started off in the usual way, a thin bright streak which quickly got thicker and brighter, then suddenly became enormously bright and exploded in a huge flash. I was lucky enough that it appeared exactly where I was looking. I wonder if anyone else saw this one, it was at 2336. To finish off I decided to point the scope at the densest part of the MW I could see and just cruise around. I used the RDF to point at a random spot, looked through the eyepiece and found myself looking directly at what was clearly a well-defined open cluster, perfectly centred. It was distinctly rectangular on 3 sides, comprising lots of very similar-magnitude stars and straight-line voids-and-stars, with just one significantly brighter star inside. It was M11, the Wild Duck cluster, I think. Lovely. That was it for the night, I packed up and retired eventually about 3am. Friday 2nd August Thank God clouds were forecast, I needed an early-ish night. Saturday 3rd August The forecast kept changing during the day. In the end it was a cloud-dodging night. I’d decided to try to use the AZ-EQ6 in EQ mode for the first time, having during the afternoon calibrated for and marked Home Position and 0-up-6-down polar-alignment position. With just my Mak 180 mounted up, I first tried for a 3-star alignment to see how far the SynScan reckoned my Polar Alignment was, but after successfully getting Arcturus and Vega, Capella was suddenly covered by low cloud which wouldn’t go away. So I just guessed for Capella and carried on. I was very tired so it was only going to be a short session. I quickly skimmed through Albireo and Almach for a comparison (Almach my favourite such lovely colours); had a brief look at the Epsilon Lyraes (really sharp and clear); and noted that M13 through the 7” aperture was nowhere near as good as the 12” obviously. My tiredness overcame me at that point and I had to go to bed. All in all a very satisfying long weekend, and I’m back in the same place in 2 weeks for a fortnight weh-heh! Bring on 2nd half of August. If you’ve got here, thanks for reading. Cheers, Magnus

    Spotted Luna a short while ago, low in the south, first quarter. Still very light, but clear, so I put the GoTo 8SE into action just to do some observing since I've not been out for over two weeks. Hercules and Atlas were clear to the NE, Hercules with that large crater in its floor, and Atlas (of similar size) a little to the east. At x102 with the 20mm TV Plossl, the view at this level of light was much crisper and contrasty than with the 20mm 100 deg Myriad - and no Ring of Fire. Must get more good Plossls! Nice and mild after all the rain - T-shirt conditions, plus a tasty beer. Let's see what transpires as the evening wears on. Good to be viewing something once more! Doug.

    Yeah - sadly, I didn't get more detail as the Moon went behind trees. But the most significant outcome was how much clearer and cleaner the view with the Plossl was compared with the wider angle EP. I might fancy lower FL Plossls, except that the eye relief goes right down! Doug.

    Looking at windy.com it seems that early on Saturday is going to be the worst of it. I wouldn't fancy being on the Cork to Rosscoff ferry this weekend A chap that works with us is on holiday for the next few days, planning to be in a 13m racing yacht sailing out of Falmouth. Somehow I suspect they might decide that discretion is the better part of valour and sail to the nearest pub instead James

    Hi All, Entering my DSLR imaged image of the Centaurus Radio Galaxy. Imaged using a Astromodded Canon 40D DSLR in natural color through a 8" SCT at F10, 2032mm focal length. MG

    A few months ago, a coworker gave me a scope his grandfather bought and stored away. It was never used. It was an ETX 90 RA in new condition. I had named the scope Cassini. Tonight it was time to see what it could do. I had never used MAK before, much less owned one before this. I had heard people refer to them as planet killers due to outstanding performance. Well I'll believe it when I see it! I had planned to view Jupiter, Epsilon Lyrae, and Albireo first. Then I was going to try some star clusters. Well sometimes plans fall apart! I first tried to find Jupiter. I popped in a 26mm plossl and looked in to go ahead and get focus. Nothing but deep dark blackness! Hahahaha I didn't unscrew the objective cover! I remove the dew shield, take off the cover and replace the dew shield. I look in and focused on a bright star. Next I point the scope at Jupiter and peer into the finder.....well fiddlesticks!!! I had forgotten to align it. No big deal. I sighted down the tube and looked on the EP. WOW!!!!! There it was in all its glory! Even as small as it appeared, it was very sharp and crisp. The detail was just staggering! The equatorial bands were super sharp. The four Galilean moons were sharp bright pin points. Io to the left of the disc, with Europa, Ganymede, and Callisto to the right. I took a moment to align the finderscope on Jupiter and got back to the awesome view! I increased the mag and added an 82a light blue filter. This revealed temperate details and polar shading. It was all in crisp detail! I now understand why MAKS are planet killers! I had fantastic views in my reflectors over the years, but none compared to the sharpness of the ETX 90. By this time I had forgotten about doubles and clusters. I swung the scope to Saturn and looked in the finderscope. I centered the planet and looked into the 26mm EP I had put back in. As tiny as the planet was, it was obviously a disc surrounded by a sharp ring. This was despite the hazy sky getting even hazier! I put in the 9mm plossl and focused. Gorgeous sharp view with Cassini's division stellaring in and out. I put on the 82a filter, but removed it quickly. The haze was getting thicker and darkening the planet. I next decided to push the envelope and raise the mag ever so slightly. I popped in the 26mm into a 3x Barlow. This gave crisp views that would occasionally soften, then crisp back up. Cassini's division was no longer stellaring. It also revealed polar shading and a lighter and wider equatorial region. By this time the haze turned into full blown clouds. So I packed up. Little Cassini performed amazingly! I now officially have a scope for rocking the planetary views! Its also official that I'm a MAK fan!! Keep looking up!! Rob

    in WL i find a ND moon filter works wonders with detail of spots it adds to the contrast, im not really into the mechanics im really just here to see the sights and the sheer mightyness of sol even tho i ive picked a bit of the science a long the way im not one to get overloaded with it charl.

    Peter, is correct. with single etalon solar Ha scopes (+/- 0.7) and poor characteristics ( poor blocking) can show the Photosphere as a “solid” edge with the Chromosphere suspended above at the limb. with tighter bandwidth (and effective blocking) the photosphere is suppressed and only the Chromospheric edge is seen.

    I think that's the Chromosphere layer, the Sun's "atmosphere".

    Regarding a 5mm EP if funds will not stretch to an SLV, a very nice EP, then the BST Starguider is a good cheaper alternative.

    I can confirm that. Hyperions and fast scopes don't mix.

    Just to add to what has been said so far, I was able to see the main bands with small amounts of detail and the Great Red Spot at just 74x in my 4" refractor, two nights ago.
