    Hi, I am now up in the highlands, but got up early and took 12 captures for a mosaic this morning before setting off. As I was short of time, I decided to try Alexandra's method of stacking all 12 frames in AS2 at the same time whilst I did my packing. It worked out okay and saved a lot of effort, fiddling with every frame. I am not sure if the result is any less good, I would have to stack it this way and the more traditional frame at a time to be sure, but it looks okay to me. So it looks like it is thumbs up for the 'Alexandra Technique'. Of course we have driven up in wall to wall sunshine and there isn't a cloud in the sky just now, hope it stays like this as my Lunt is in the boot of the car.

    I had the privilege to witness an awesome solar flare today. It began just before 2pm and lasted for quite a few minutes. When at its peak it reached 'M' 7.2 on the GOES X-ray data graph. It was fantastic to see on my computer screen while I captured it. I have never witnessed a flare get so bright so quickly before. It was awesome to watch. Here are 3 images taken during the event. I captured 1000 frame avi's and stacked the best 10% in AS!2. False colour and tweaking in Photoshop CS5. I used a Lunt60t DS with a X1.6 barlow.

    I think the Leo trio were the first galaxies I ever tried sketching. I used the same scope as you but the skies were fairly good at around LM 6.3-6.4 and from memory NGC 3628 was seen by direct vision but only just.

    These are stacks of the luminance frames (5x10min subs) of two targets I imaged last night. I'm about 1/2 way through collecting the LRGB for both targets. Taken with a TV NP127is refractor and Atik 490EX @ 1:1 binning. There was a near full moon which didn't help much. These images are simple calibrated stacks (bias, flats, darks) and levels adjusted, no other processing at all. M101: ngc4631: ChrisH

    16th April 2014 - - EQ8, MN190, EFW2, Atik 460EX, OAG with Lodestar. Not the best of clear skies - wispy cloud about Also a hint of mist and it became totally imopossible after a couple of hours so this session was more about getting back into things after a long time kept indoors by the weather. Took me quite some time to get set up and to find my target. I had no previous images of M51 on this laptop to use with AstroTortilla so without the mount calibrated for direction, it took my a fair while to find M51. I set up for LRGB with 5m unbinned Luminance and 2m binned 2x2 for RGB. Finding anything to guide on was a problem with the poor clarity but I did get it working for a while. I got 3 subs of each when I noticed the guiding had failed and the third L sub had oval stars. I've yet to process all the subs and TBH I'm not sure it's worth bothering - I'm hoping the present clouds will go away and we have clear sky tonight - it's what's forecast. What I have done is take the first L sub which I thought reasonable and process that using FITS Liberator and Photoshop.

    I figured I do one of those posts to introduce myself. So I just received a Celestron Nexstar 4SE from Amazon on Wednesday and had it up and running that day. Set up of the telescope was pretty easy with a Hungarian friend assisting but the red dot finder had it's mounting tightened too much so it couldn't fit on the scope, I'd anticipated something like this and so bought my first screwdriver set with the scope which quickly sorted that problem out. I was kind of taken aback with just how small it is but it's sort of cute, it's like the little telescope that can. I don't have a power tank yet so I put in 8 AA batteries and I have another 72 to get through so should have a power tank by then. When it turned dark I took it outside to the garden and had a "doh!" moment on using the handset as I didn't see a way to enter negative longitude a quick look at the manual (reading a manual? Blasphemy!) didn't say anything so I took to Google which made me look silly, all I had to do was enter longitude and then select East or West of the prime meridian so with sorted I entered the time and date off my phone to the nearest minute and it was all ready to go Sky Align. Here we come to "doh!" moment number two, lined it up on bright star very roughly and did enter and precise line up then I did 2 more random stars which I found just slewing around the telescope, of course alignment failed. Then I notice that what I thought was a button on the red dot finder was nothing and it was actually a circular knobby thingy on the side that turned it on, with the red dot finder on it was quick and easy to align the telescope and the handset reported alignment success after aligning it with Jupiter, Mars and some random bright star (now you should be seeing why I picked the near idiot proof Celestron GoTo). Off to observing, I went for Jupiter first and it put Jupiter right in view of the 25mm eyepiece, I could see basically a big shiny disk and some bright lights around it, no worries for I also purchased a Celestron Omni 15mm eyepiece and 2x Barlow Lens, in the 15mm with the Barlow Jupiter was FANTASTIC! I could easily several bands of clouds although now I could see fewer of the moons, I also showed my friend over from Hungary Jupiter and he found it wonderful too. Next target was Mars, this time the goto didn't put Mars in view of the 25mm eyepiece so I had to do a bit of slow slewing and then it was in view, Mars was an orangy disk in the 25mm but with the 15mm and Barlow I believe I could notice some detail although this might of been my mind playing tricks. My friend left at this point but not before mentioning he now wants a telescope. Final observing, next up as the last target before I went in was the moon, it was low over buildings and with trees in the way but I could see it clearly at some points, and it was a great view. So next I'm going to look in to doing a more precise alignment so the scope goto works better and try looking at some double stars, tonight should be okay so I'll see what I can get. TY if you read through all that.

    Hi folks, the first full moon in spring says when Easter has to start. I captured the rising of this special full moon behind the castle Hochosterwitz in Carinthia. btw I captured some impressions of the castle: Rising of Spica and Mars higher in the sky http://www.starrymetalnights.at/Bilder/BurgHochosterwitz_Mars.jpg Castel at night without moon http://www.starrymetalnights.at/Bilder/BurgHochosterwitz_Pano.jpg @ dusk http://www.starrymetalnights.at/Bilder/BurgHochosterwitz_Daemmerung.jpg and a HDR: http://www.starrymetalnights.at/Bilder/BurgHochosterwitz_HDR.jpg Regards Werner

    I got this scope last August for my birthday and wanted to tell you about my experiences with it and what I have been able to see. I live in a large town in Bedfordshire, UK and therefore my skies are light polluted. My back garden shows half of the sky facing North, but I can see objects high in the sky over the top of my roof in a southerly direction. I also have a large tree that blocks the NNE section of the sky, but I can work around that. My garden is fairly dark if my neighbours don't use their proximity lights The 150p comes with two eyepieces a 25mm and 10mm, both have proved useful and whilst not of the greatest quality they start you off well. Once I got the scope I had to decide what I wanted to see, early on I was just using Stellarium and looking at what was around in the sky and then seeing if I could find those objects and that was fun for a while, but I soon wanted a more methodical approach to observing, so I looked around for lists of deep sky objects and found the list of Messier objects and then another characterised as the Herschel 400 from here. I took that info and made a spreadsheet. I then started to prepare for observing sessions ahead of time, making small diagrams of the approximate location of the object to observe with the stars I might be able to see as signposts. In my spreadsheet I recorded what I have upcoming to observe, what I have observed and some notes on the date, time and conditions. So in my first month of observing I was able to see: 09/08 M31 Andromeda galaxy large smudge Mizar and Alcor in Ursa Major easy split NGC884 Cassiopiea Double cluster – fantastic! NGC869 Cassiopiea Double cluster – fantastic! 11/08 M13 Hercules Globular cluster Round smudge 12/08 M57 the ring nebula in Lyra Could just about make out the hole in ring nebula with averted vision 26/08 HIP107259 Carbon star Garnet star in cepheus 27/08 M81 + M82 Galaxy Saw M81 + M82 in same field of view in Ursa Major M52 Cassiopiea Open cluster (seems feinter than stated mag) very pleased after yesterday's frustration, needed laptop outside to do it. HIP48635 Binary 27/08/13 A+B both mag 10.45 so I can see to this level of star mag!

    no you are not missing anything. barlows are useful for doubling your magnification, extending your eyerelief even slowing down your scope if you need to bring some unruly eyepieces into line you don't need to do any of this so You don't need a barlow gary

    Good seeing conditions on the 15th and similar to the 10th. Spent a couple of hours on Mars and then slewed to Saturn. Here is the first Mars run I have managed to process so far...have loads of data that is mounting up, so its good to have the holiday weekend on the horizon as I hope to catch up with the processing!!!

    Yep, I have just fiddled with the secondary and yes Scooot is on the mark. It will do the same thing but with less overall changes so I like this method. Excellent. Also wookie, cheers for that link earlier. It goes straight in the bookmarks. Now to try and fix the rest before Jupiter sets. Many thanks guys. For now I seem back on track and wouldn't of thought about moving the secondary so drastically on my own.
  26. 2 points
    Yep tilting the focuser will do it but I suspect rotating the secondary slightly will fix it whilst leaving the focuser flush with the tube.

    Hi everyone. I am just posting a reprocess of the first Mars I captured on 14.04.14. In my earlier post both Stuart ( Space Cowboy) and Pete (Theo) suggested there may be more to pull from the image. Well I have take their much appreciated comments and advice (thanks guys!) and had another tweak and also enlarged the image slightly. Hope to get a few more within the next few days! Best regards, Ralph

    Hi folks. With ardbeg74 and his neighbours having kindly secured some clear skies in the South East last night, I thought I'd get the scope out and make the most of it. For some time I've been intrigued by reports of people tracking the ISS in their scopes and being able to make out the solar panels and various orbital segments. I've been particularly intrigued by people using a GOTO scope like mine, such as Dude_with_the_tube in this report. I've also recently downloaded SatelliteTracker and so I thought I'd see if I could get it to automatically track the ISS. However, after a brief test with another satellite half an hour before ISS was due to appear I realised that it wasn't going to work... in theory I believe my SynScan handset understands NexStar GPS commands (and indeed when I tried to track a satellite it did move the scope towards the right part of the sky) but it seems that the SynScan doesn't correctly report its current position to SatelliteTracker and so after a few seconds the scope stops moving and an error comes up on the laptop telling me that it doesn't know where the scope is pointing. (As an aside I'd be interested if anyone else has seen this problem and has found a solution.) So I then moved to plan B which was to move the scope towards where I expected the ISS to appear and select slew rate 6. I actually found SatelliteTracker's real time view of a satellite's alt & az quite useful in getting the scope to the right place and get ISS visible in my finder scope, but in retrospect I could have got the same info from Sky Safari on my phone or even looking at HeavensAbove or CalSky to get some co-ordinates beforehand. So no laptop next time... Once I saw the ISS in the finder scope it was pretty easy to get it into my 16mm eyepiece's field of view and keep it there, giving me a 75x magnified view. I must say, the image completely blew me away - I could easily make out the 4 solar panels as four golden coloured rectangles and a series of bluey-white shapes clustered between two sets of panels that were the various orbital segments. I tracked it for a minute or two and then found as it approached the zenith I needed to increase the slew rate to 7 to keep up. I lost it at the zenith as I couldn't continue without quickly rotating the mount through 180° and by then I'd had a stunning view for a couple of mins so just watched the ISS disappear with just the naked eye. I'd really encourage anyone who hasn't done this to give it a go - absolutely worth the effort! I would imagine it's probably even easier with a manual dob After that triumph I turned my attention to the Moon. The last few times I've looked at the Moon it has been showing other people various features so I've tended to stick to the 4 or 5 features that I can easily find/talk about and just repeatedly observe those. With my recent Sky Safari purchase I wanted to spend some time on my own just using the high-res map in the app to identify features as I moseyed around the surface. I ended up spending time in the area around the Apennine Mountains at the edge of Mare Imbrium and really enjoyed some superb views using my Delos and Nagler eyepieces between 150x and about 266x magnification. One curious feature I noticed was in the Apollo 15 landing area near Mons Hadley that strongly resembled an eye! I think it was Bela Crater and the nearby Rima Hadley lunar rille - I wondered if anyone else had looked in this area and spotted it? I decided to finish the evening by taking a quick peek at Mars & Jupiter. Mars was a complete washout compared with Friday night's view - it varied between a shimmering peach-coloured featureless blob to looking a little like a tennis ball (i.e. two grey lines in the pattern you get on a tennis ball). There were a couple of very brief moments when I could just about identify Syrtis Major and Acidalia Planitia. In the end I gave up and turned my attention briefly to Jupiter and just managed to catch Callisto emerging from the planet's disc - it genuinely looked like Jupiter had a pimple on its face. At this point the wind was picking up, Jupiter started to move behind a tree, I realised the Moon was also behind a (different) tree and my wife came into the kitchen and flooded the back garden with light. I took this as a sign that the effects of ardbeg74's sacrifice had worn off so it was time to pack it in and go indoors for a cuppa. Apologies for the rambling, but all in all I was quite chuffed.

    The Mk2'a of the zoom were very good and had no problems (mine still works fine after 4yrs). But Alans right - two to three years ago when the early batches of Mk3's was introduced, a lot of folks reported them seizing up, especially on very cold nights. Sounds like you may have one of those. They're not "the best" eyepiece - but are considerably better than supplied eyepieces, very flexible to use having several different functions, very good value for money (when they work), and ideal for newcomers with their first scope wanting an instant range of focal lengths whilst building a decent collection of fixed length pieces (imho). But they do have to work - I would approach Baader with your case and see if they'll offer a sympathetic solution - they're a small company who do try to keep customers satisfied from what I've heard.

    Well I picked them up, got them home and after a cuppa cracked on. I had a look at both mounts and decided that the one that was in bits being slightly newer was going to be the one to live again. It was missing the dec worm carrier, although all the parts are in bag other than the carrier itself. And the dec spindle had been removed and was in bits. So I have stripped the dec complete from the second mount and fitted it to the first. Altogether it only took a couple of hours. I now have one complete neq6 and a pile of spares. I greased everything as I assembled as there was hardly any grease in the mount and looking at what was there it was spotless so I don't even think the mount has been run! I have powered the board and it lights up. I now just need to make a cable up so I can use my handset and test it. So it looks like it's going to be a very good outcome I'll post a piccy later.

    Yep. I don't have this rig anymore, but it worked really nicely. 4m focal length 8" Mak for high power, and 106mm apo triplet for Widefield. The AYODigi mount held them both as it they weren't there and moved very smoothly. The other thing I do do still is white light solar and Ha with a PST side by side. Very nice to have both views to compare, each have their benefits. The white light is with a TV76 and Lunt Herschel Wedge. Stu Sent from my iPhone using Tapatalk

    I sometimes take a Skytee-2 out with a Mak 127 on one side and a Tal 100RS on the other. I also sometimes mix and match with the Meg72 and 200P - any combo really - just to demonstrate differences for anyone who's interested. On the tracking mount I also use a side by side arrangement for the Ha solar scope and the Meg72 with a white light filter for comparison. Always a pleaser cos the views are so different. It's all fun to do and gets a good reaction as well as being helpful to anyone who has never used a particular scope, or is trying to choose what to buy. I'm going to put a third shoe on the skytee so I have the option of two larger scopes and a small one.

    Okay, we all know that the moons gravity pulls the tides up, but on Monday while we were at the beach in Bude, the tide was high at about 18:00. However the moon wasn't overhead until around midnight. How is this so? Shouldn't high tide happen when the moon is up above? Or does the Earths rotation cause a lag?

    Look at getting a power pack and then the EP's. Once the batteries run down the GOTO capability is lost and the mount will wander around. That has been my expererience with the 6SE, Look at 50x 100x and 150x without the barlow for ep magnifications.

    Yes! mine arrived today and I've just been out with it until it clouded over. I'll do my best to give you a mini review Mine arrived from FLO the very next day after ordering, thanks FLO! The decorative box it comes in is very nice, worth keeping. Very little assemby required of the scope itself, just the red dot finder to attach and the bearing nuts for the alt/az to adjust. The mount looks and feels quite sturdy and the alt/az bearings are nice and smooth. The rack and pinion focuser is also smooth but was caked in far too much grease on and around the rack so I spent about 10 minutes carefully removing the excess so as to not get any on my EP's when in use. The focuser is still sliky smooth after the excess grease removal. One of my main concerns about this scope was its collmation beings the primary is f/4 and fixed but I needn't have worried, looking down the focuser the secondary looks bang centre and first light showed almost perfect doughnuts on defocused stars on axis, very impressed for f/4! Jupiter was out the front so I placed the scope on the pillar of our front garden wall and found it almost straight the way with the supplied 25mm lens at mag x16. Jupiter showed as a bright disc with four pinpoint moons, there was plenty of FOV to frame it at this mag. I switched to the supplied 10mm giving 40x and this time 2 bands could be seen although there was some lateral colour showing with this lens which was distracting so I switched to my own EP case. I chose my 7mm circle T ortho giving 57x, this gave a surprisingly good view with this scope, better than I'd imagined, there were 2 crisp bands and hints of finer structure set against a crisp disc, very nice I thought! I changed again to my 30mm Vixen Plossl giving me just 13x and scanned around, the stars were plentyful even with the street light literally across the road from me, I came across a nice open cluster not sure which but it almost filled the FOV. I then decided to take the scope out the back despite my neighbours security light blaring into my garden. This time I had the scope on my lap on a chair so there was a bit of wobble like when using a pair of bino's. I pointed the scope East and almost instantly saw a round smudge near Sirius which I think could have been the M3 glob cluster, then over to where Mars was rising low on the horizon through the trees, I could see the red colour of mars very clearly at 13x and decided to go in to let it rise a bit higher which is when it clouded over sadly. Verdict so far in a nutshell: A well made and ultra portable scope which has already showed me some surprisingly good views on day one! The optics are ace for such a cheap scope, I can't imagine a better little scope to take camping and I'm very much looking forward to taking it to somewhere really dark. I very good way to spend just 97 quid I think Chris

    I love my little ST-80. I took it to Spain and got some snaps of Sagittarius etc I'm really proud of. Scope small enough to fit in hand luggage, cheap enough to take travelling. Tripod, EQ1 mount + counterweight went in big suitcase in the hold. Enjoy!
