    Ever the optimist decided to have a go at some planets ZWO ADC and Astronomik 642IR pass filter to give a couple of options. The sticker on the box was right as it arrived with a liberal amount of cloud and rain. Dave

    As we all know the planets are difficult this year with the low altitude, but we still keep getting out there and doing our best! This was my best image from the 2nd July. The first image was processed in Registax 6, and the second one in Fitswork4. 8" SCT, ASI224, ADC, 2x Barlow. Capture size was around f24, and the images reduced to 80%. Saturn is shown at capture size. Angie

    I returned home from a meeting of the Border Astronomical Society that night. Full of anticipation, I went out to my domed Observatory, rolled up the shutter, turned the opening to face the local meridian. Set the stepper motor drive in motion place a 12mm Plossl eyepiece in the focuser, I turned my 12" home made Newtonian to Jupiter and waited patiently for the Impact areas to rotate into view. They slowly appeared ion tandem, one dark patch after another, until there were no more. I had never felt such Awe and excitement as did that memorable night. I was pleased.that shredded comet had been pulled in by the mighty Jupiter, and prevented mother Earth from a possible future meeting with Shoemaker Levy 9. Ron.

    In awe of all the images on here … I am just getting started with astrophotograhy and still don't understand the finer points … and also having trouble with focussing issues , but seeing images like this inspires me so much . Just got my 130pds (17/7/2019 ) and waiting for a clear night . I already own a small refractor but I chose the 130pds for visual use as well as imaging . What I particularly like about this scope is its weight .

    Very good points made Moonshane! The comfort difference is huge and very likely a significant part of the reason more detail is seen. Both the eyes and brain are operating in a more normal mode. I always prefer magnification on the lower side. The sharpness and contrast are stunning. Overpowering a scope, while some like to reach the upper limits, is just too mushy for my liking. And, depending on the quality of the scope, of course, getting the correct focus becomes more difficult. Another plus for binovision is that at a given magnification, the object you're observing appears larger. Very nice eyepiece kit! The TV Plossls have extraordinary light throughput which matches up well with a binoviewer. At the longer focal lengths Plossls are comfortable. But the Panoptics are gems, indeed! I've never had the pleasure of using the Maxbrights. I would say that mixing your viewing between monovision and binovision is a good idea. Kind of like keeping in shape for either. Some try binovision and have difficulties, likely caused by mechanical deficiencies with the viewer, and drop it for good. Others like it so much they won't do any monoviewing. I'd like to keep both options open but I don't know how it will end up. The sky here is so poor, lunar, planetary and some doubles are really all I can do, and they lend themselves to binoviewing. So we'll see. Thanks very much, Moonshane! All the best! joe

    Well after a complicated negotiations with the House Management Team, a plan has been drawn up and fully approved. I have suffered multiple spotlights spoiling my Astronomy at home for a couple of years, driving me to almost stop observing from home. But I can be a stubborn wotsit so had grand plans of an observatory, but time, funds and health this year have put paid to this idea. My plan is to shade an existing concrete base in the garden to observe from, compromises needed, but it works as a location. Here is the area, it was a 15 Feet x 15 Feet concrete base used for a childrens frame pool, now long retired. Showing the first batch of plants now residing trying to block lights. I have reduced it to a 9 Feet x 15 Feet base. Surrounded it with Portuguese Laurel last year, but not tall enough yet, so have plans for a fence. The area to the left where you can see a Football Goal is next door, they don't like the dark and don't like Astronomy. The image under shows some of the lights that I contend with, there are a good number more. I tried lots of planting and spent £1800 on shrubs, but only partly resolved the issue. So the plan is to allow a 9 Feet x 9 Feet observing pad and a spare area for future storage** storage** is code for a 8 Feet x 6 Feet Pent shed in the future. It could serve as a scope or mount store, warming area and a place to ponder the world at night. This is the first post and has been in progress since October 2018, but a stay in hospital over Christmas and ongoing issues since have slowed my progress. Well in reality stopped it for 6 months. Now just starting again at a slow pace, as I have a few minor mobility and strength issues still, but getting better each day. Enough about that though! It is not the observatory I dreamt of, it is not even the shed I want still. But it will be a good area to observe from and once the fence goes up it should block out the spots that blight my Astro life!!

    Hey all. Been a while since I have shared any images. This is my first "advice" post. I have been happily doing full disc shooting with my regular camera gear - seriously love it. I have pushed the limits of what I can do and am ready for more serious gear. I have on order a ZWO ASI183MM camera. I don't own a scope yet - I plan on imaging with my current lenses still for now. (adapters sourced and one ordered already) Now... some context. My interest at present, and likely always, is Lunar imaging. Maybe some planetary one day if I have the aperture. Would be nice to LOOK at some DSO at some point, but I don't foresee wanting to image - I just don't have the time for one thing. I NEED a fast easy set-up. More than hlaf of my sessions are very time constrained - I have a busy family and work life and sometimes I need to be done in less than an hour - I currently aim for 30 minutes when skipping out from work or doing an after work session on the way home at midnight. (Gun and Run) I want to have either both my lens set-ups (300/2.8 and 400/4.5) or one lens setup and a scope on the mount at same time. After taking up TONS of much more knowledgeable friends' time recently I have come down to these two options (I will not rule out others, but I will admit to being pretty overwhelmed with the whole thing at this point.) I live in Canada so prices are CDN. Option one (more mount than I need?) iOptron AZ Mount Pro GoTo Alt-Az Mount with Tripod ($2028 CDN all in shipped from B and H) or Option 2 Celestron NEXSTAR EVOLUTION 6 ($1880 CDN all in from a Canadian source) Cheaper.... and with this I get a 6 inch scope. I will add to this, that I can and plan to borrow scopes from my local RASC where I am a member. They have several apparently. Thoughts??? Much Thanks in advance Mike Oh... here is a recent fave with my old kit. (dslr now sold) Sony A77ii + Minolta 400/4.5 + 3X TC + 1.4X TC. Lots of single shots, lots of stacking, lots of processing. lol Two part mosaic.

    Hi all, my first images of wide field imaging of cygnus and scutum star clouds taken while on holiday a few weeks ago. Canon 1000dm, standard canon lens, omegron mini clockwork drive. Think my polar alignment was a little out. stacks of 5x3mins stacked in Dss. Edited with the new adjusted second image of the scutum cloud as it was suggested it was to green, which I agreed with.

    Jupiter from the 11th at about 11:14 PM EST. Same setup with the asi-120mc-s and the xt8. Cut out the empty frames and centered with PIPP. Stacked 2,600 frames in AutoStakkert and did wavelets in registax. Also, I noticed what looks like a long flake that came off the Great Red Spot and is getting swept into the Southern Equatorial Belt. Is this the case and has anyone else noticed this?

    After receiving great advice from this group, I decided to purchase this TeleVue 2x Barlow! It's going on my Skywatcher Evostar Pro 80mm. I have an ES 6.7 eyepiece I want to use with it. Can’t wait to give it a go!

    Last night's conditions here produced a clear sky and excellent seeing for an hour even at Jupiter and Saturn's low altitude. The Moon near to Jupiter seemed almost to enhance the seeing. A transit of Io was just beginning, and the small disk could be seen just beginning to touch Jupiter, and then moving across as a clearly-defined creamy-white disk across the North Equatorial Belt for some distance. Ganymede was clear as a slightly darker clear disk, with minimal flaring around it from the seeing. Both Jupiter's main belts were beautifully defined for 20 minutes or so. I never caught the shadow transit as cloud had descended by then...... Saturn was very well defined, with the view snapping in and out almost like a NASA image for the odd second or two, with a razor sharp Cassini visible all the way round and plenty of band detail on the disk itself. Scope: 180 Mak, x190 for Jupiter, x270 for Saturn, both with ADC. Chris

    Blimey John, with Saturn almost overhead I'm able to give it 375x with my 4mm EP and it stays pin sharp with incredible details, C Ring, Encke Minima, Enceladus etc. etc. Give it a go with whatever power you can!

    As this is in the observing section, I don’t think the OP is looking for imaging solutions but a 40mm EP may just about work. A FOV calculator (like the one available on the FLO website) will show you some options.

    I think it's unlikely that you would image a full disc, around 600mm focal length is usually the maximum, your combination would be working at over 2000mm. Not sure about a DSLR though.

    The skypod did OK with its limitations. A very reasonably priced dome, compared to alternatives available. I was struggling with it, as my scope was bolted down and so it was difficult to find a single ideal point to secure the pier and so with the planned move when I retired, it had to go. The Scopedomes are in a completely different league for design and build quality. I am STILL working on the terrace - almost done, the sub-structure is repaired and now watertight and I am 75% finished laying new tiles. Then need to grout them and then get back to the obby... The weather here is glorious, but too hot to lay concrete, screed and adhesive. A lot of this needs to be done in the evenings... I need to go back to work... for a rest !!! Gordon.

    I would agree that even a small scope means you have to 'think' about taking it outside, but a pair of bins is no thought at all. I would go for either a 7x50 or what I use the most, a 10x50. Any bigger than that and realistically you will need to Tripod mount them..

    You should be able to get KStars to slew to the object in question, then plate solve to find out exactly where you're looking. KStars should then slew to the right place. Further solves (if required) should get you spot on. At least that's how I understand it. I haven't quite got it working yet but hope to next time we have a clear night without the moon shining straight down the spout! If you start with the mount set to point to Polaris roughly, KStars should do the rest. Yes, I have an observatory with fixed mount. I stuck an "N" on the mount to show north. The second slewing position is obvious. I do have a GEM though and know nothing about A-Z mounts.

    If it was supposed to be so damaging, I'm surprised no one has bothered to keep an eye on it after its discovery. But I guess we should at least be encouraged by the fact that they can't find it in the dangerzone.

    I can confirm that the v3 handset also works, though at Stu says both handsets need the SynScan AZ cable and not the normal cable shipped with EQ mounts. The cheaper Skywatcher cable works as well but isn't as nice as the one linked to by Stu. I have used an ED100 on mine but it needed mounting on an HEQ5 tripod and pier extension which somewhat defeated the point of the mount. It is now restricted to a WO ZS66SD a humble ST102 or Lunt LS60DS. Ade

    On targets that emit O-III lines, they are really effective. The Veil and Owl nebulae spring to mind but there are a number of others as well. The difference that an O-III filter can make has noticably more impact than a UHC filter on such objects. I've owned both the Baader O-III and an Astronomik O-III and much preferred the latter. The Baader is decent quality but it's band pass is quite a bit narrower than the Astronomik which, for me, resulted in dimming of background stars more than I wanted. This characteristic also means that the Baader is not effective with smaller aperture scopes whereas the Astronomik O-III most certainly is. The illustration below of the impact of a good O-III filter under a dark sky is not exaggerated in my experience:

    Hi, Wow, there really are some nice photos on this thread, definitely worth reading! These were a couple of quick shots from Monday "morning", Saturn with the NEQ6 and ASI120MC. 1. Saturn from a video of around 15k frames, with 2x (dreadful) barlow. Its a small image, really I could do with getting a decent quality 3x for this kind of stuff, still using the one that came with the explorer 130! 2. Again with the Barlow, this time a single 5 sec exposure to show Saturn's moons: (L) Dione, (R) Tethys, just under the planet is Rhea, and under that is Titan. I was able to see all four visually with the 6mm eyepiece, although it was a bit of a struggle. I purposely didnt look at the position of the moons beforehand, its so easy to imagine faint dots! Clear skies! John

    Hi all, Some feedback on the Baader 4,5 nm O3 filter; I like it a lot! It is a very nice match to my Astrodon 5nm h-alpha filter. The stars are very similar in shape and size, which will allow me to make some nice bi-colour images. If I may give one small point of criticism; there are again some halos noticeable (remember the old 8,5nm O3 filter) around very bright stars. It could be something else in my imaging train, not 100% sure yet... But overall I am happy with this purchase. It will be a return for me to colour imaging after shooting b&w for a long time. Here is the first light; a quick and dirty bicolour on NGC7000. Scope was my 10" newton, exposure was 2 hours in HA and 2 hours in O3. Colours mixed as HA:O3:O3. Thanks, Regards, Pieter
