  1. Failing to pack one small cable put my planned imaging kit out of action for SGL 11. This turned out to be a blessing since I was free to have some DSLR fun both wide field and with a Canon 135mm lens and an 1.4 extender. So 189mm at F3.5. Unguided on a Tak EM200 about 12 x5mins with an Ha clip filter and 12x3mins with a CLS filter. No laptop, no cables, no sweat. Wandered around the site getting some lovely views though big dobs and watching Bobski do battle with his mount. So it's no great shakes and I've shrunk the pics down to hide the gross imperfections but here's my rough and

  2. I finally managed to get all things running satisfactorily (not perfect) . So managed to get the longest integration on a target so far. I kept the ISO low at 400 just to get longer exposures not being washed out by LP. Lights: 50 x 300 s + 30 x 180 s Darks, Bias. Flats produced a strange bright pattern in two corners due to Meridian Flip. That was just too much for me to handle in PS. This is a crop of the image taken with 130PDS and Canon 1100D with Baader MPCC III all mounted on Heq5 Pro. Thanks for looking. Please suggest corrections or point out flaws. I wish to keep l

  3. Below my first mosaic, which was created from 25 AVI (a total of 25 000 frames). Material collected with Schmidt 11" + focal reducer F/6.3 (1.764 mm) + camera ZWO ASI 120MM. Mosaic composed by means of Image Composite Editor - a free software, very powerful and simple application for panoramic images. http://moje-nocne-niebo.blogspot.com/2016/03/ksiezyc-moon.html# Mare Serenitatis (650 x 650 km) with two mountain ranges Caucasus (in the upper part of the photo) and the Apennines with a beautiful strait between them.

  4. Two wonderfully clear nights in a row after....I kid you not...4 months of almost steady rain here on the coast. We have had maybe 6 days since November were it has not rained. Of course the Moon was out for both nights and looking amazing so it dictated the evenings imaging plan. I've yet to try a mosaic and after seeing some fantastic work here from others decided to give it a go. Not as easy as I first imagined. I have 4 scopes with a variety of focal ranges and combinations I can do but decided to use my SCT with a focal reducer/corrector and my ZWO to go about it. Turns out it's a wonderf

  6. Had a session a couple of days ago (first in ages!) to try out Altair's mono GPCAM with Star Analyser. The Moon was a bit too bright to get the best spectra, plus it was in the back garden with lights from neighbours, street lights, flats opposite, etc. So I turned the scope (8" with 6.3 focal reducer ) on the Moon, and this is the result. I took a 300 frame SER file using SharpCap and put it through Registax. I skied in the shadow of Mont Blanc a few years ago in Chamonix. Interesting to see Mont Blanc on the moon as well, though I doubt the skiing is any good. Alan Shepherd played golf

  7. My first go at M101. I underestimated how faint this target was, and i probably shuold have picked a different target with the half moon up. Either way i managed to capture 62x 120s exposures at ISO800 with the Canon 550D and the Explorer 200, and although faint and noisy there's still some details showing up.

  8. Hi all This is the 2nd capture i made on the night of the 17th Captured with Mak 127 using ASI120mm with 2x Barlow attached, this was run through PiPP first same as my last capture however when i run it through Registax i just end up with a white screen and no image, so i ended up running it through Autostakkert and this is the resulting image i have had to crop the image somewhat as bits of it were missing pretty sure it's down to human error on my part still quite a bit of learning on the software side yet 1010 frames captured with Sharpcap (yet to try Firecapture)

  11. So Wednesday night was a bit hit & miss. I went out to try and do a little lunar imaging, but the skies were awful. I knew transparency was meant to be shocking, but this was in a whole new league. I had not let the scope cool properly and wanted to grab a few shots to see if the skies were really that bad....and yup...they were. I had heard the jet stream was going to move off sometime before midnight, so decided to sit outside and wait it out. every now and then I would run a quick capture, and run it thought AS2 to see if it was improving...then the clouds rolled in...They never mention

  12. This is a nice fit on the chip of the dual Tak 106/full frame and I did it a while back with Dave and Zoe (Gothastronomer.) Last week we had another night on it with Mr and Mrs Gnomus, though for some reason the backgrounds were a bit messy in that set. Combining the two shoots made for lovely deep data to play with and I already had a 'Markarian's only' at higher resolution from the TEC140 so I put the lot into the pot. Here we go. Stars were masked to hold them down relative to the galaxies. To show it full size on the new forum I'm not sure what to do so I'll post this and then e

  13. This mosaic really gave me some headaches, as the flats seemed to cause no end of trouble. I must have stacked the data a dozen times with flats processed differently, before giving up. I got a rather blotchy disk with a clear gradient. Not good. It might not look too bad, but any application of curves brought out the problems clearly. I then decided to do a little post-processing trickery. I first selected the disk in Gimp, with the ellipse tool, and mirrored it horizontally. I then loaded it, and the original in ImageJ, converting them to floating point. Adding the two images and

  16. First bit of imaging for quite some time thanks to the good old UK weather, took these on 15/16/17th March. Anyhow, 2 hours at ISO 1600 at 1 minute lights plus flats darks and bias, stacked in DSS and processed in Photoshop CS2. SW 200P focal reducer, modded Canon 450D, HEQ5 with EQmod. weather: bright half moon, high alt thin cloud thanks for looking, all comments +/- more than welcome.

  17. Hi all, just noticed there's a close conjunction of M1 the Crab Nebula and 12th magnitude comet 81P Wild this evening (19th March). Could be an interesting imaging opportunity, although the moon and weather will probably put the kybosh on it.

  18. Well done Vicky! Your processed image looks great!! And lol! the kids were seriously ragging my dob about weren't they? haha!! Gain, your globe is still in one piece by the way although we caught Damian trying to destroy it on several occasions. Including wanting to paint it black and call it a new moon lmao!! As a punishment here are 3 pictures of the Devils Light bulb I took the other night, especially for you Damian! Oh... and this thread has now made me hungry again even though i've just polished off a homemade Chicken Tikka Massalla! Thanks

  22. Up late on Paddys night making the most of one of the few clear spells this year so far, decided to grab a quick shot of M13 rising. It was still in the murk and seeing was quickly deteriorating only managed 4x5min subs before the cloud rolled in over it. Used Atik Titan which is mono and has quite large pixels on a small chip with SW ED80. Thanks for looking and any comments appreciated.

  24. I think it's like aperture really. I would always encourage people to start with a moderate aperture, say a 4" frac or 6/8" newt before moving up the scale. You learn so much in terms of observing technique (much like Piero does with his insanely good results from a 60mm Apo) that you are bound to be a better observer when you get to bigger aperture. I think it's the same with eyepieces, you learn over time what you like and dislike, how they work with your eyes and which objects you prefer. The results from good entry level eyepieces are certainly pretty good these days. Some years

  26. The home galaxy is rising a couple of hours before dawn these days. And that gave me an opportunity to shoot at it. Well actually I left the CW of my mount at home. So what's better than simply sticking camera directly on the mount to get long widefield shots with a dark sky? I shot the Summer Triangle and Rho Oph. Presenting the Summer Triangle. Lights: 8 x 180s + 6 x 60s @ Iso 800 Flats, Bias. Taken with Canon 1100D unmodded and 18 mm f/3.5 lens mounted on HEQ5 Pro. Edit: Oops..where's the image? Now its here...

  27. Recently had a go at reprocessing a DSLR image taken back in 2014, so here it is. NGC1333 in Perseus, made up of just under 19 hours hours of 10 minute subs. Much happier with this version, been wanting to reprocess it since about a month after posting the original! I have since moved on to CCD and also got round to putting together the tiny amount of RGB i captured for M1, at under 3 hours in total. Hope you enjoy, more information about the objects can be found on my Flickr page for those interested in that sort of thing! Exposure Details: 113* 600 secs, ISO 800

  28. The Moon was nicely placed on the 17th so I took the opportunity to grab a few captures of our nearest neighbor under reasonably steady conditions for once. All taken with the 12" LX200acf and ASI174mm camera working at around F30. Pleased to get something worthy of posting as it's been some time since I have posted in this section. Hope you like them.

  29. Here are some images of the project so far. I have used a Keter 'store it out Max' - the idea being that from the outside it looks like where we keep the kids bikes or the mower. Inside I keep me baby....130mm reflector. I have set the tripod so that when I place two tripod legs up against the bottom of the floor it is aligned. Other features include a mirror image moon map, a plastic 'sleeve' where I keep my planisphere when observing, a little stool on which I place my tray of eye pieces and a red cycle light I can use to see when setting things up. I'm still planning some mo

  32. This is one I did a few weeks ago. 12 X 5min, iso 1600, DSS, Photoshop. Originally a widefield with M 82 but I wanted to display it on its own, so I cropped it and sharpened the galaxy, luminence sharpening, some high pass and unsharp mask, just on the highlights, and smoothed the rest a bit. Its probably a bit of a small object on a DSLR for a close up, but I am quite pleased with it and plan to put it on the lock screen of my phone!

  33. Having purchased an IS camera from Helen at SGLXI to pick up lunar imaging again, I thought I'd better do some!! I have forgotten heaps on processing lunar images, so learning again from scratch! Feel free to comment robustly And I'm pretty sure it's Plato... but I could be wrong!!! So, I think there are about 1,000 frames from 5 videos in this, but this was my first time using Autostakkert, so can't be sure! Camera: IS DBK21 Scope: GSO RC f/8 - no barlow Mount: EQ6 Capture: SharpCap Processing: Aligned and stacked each video in Autostakkert, manually al

  34. It's been so long since I managed to get a half-decent session in. Rusty. Anyhow, with the scope cooled a dimly-remembered set-up and alignment bagged these shots from 17 March. Seeing got steadily worse over the 2 hours. I like the way the phase picks up the fluid nature of the wrinkle ridges to the north of Pitatus in Mare Nubium. The rest are "old friends" revisited. Seemed to pick out Hadley Rille pretty well too. All Skymax 150 Pro and Zwo ASI120 mono, red filtered. Enjoy. Thanks for looking.

  35. Promising evening since this afternoon! I was checking the sky from the window at work every 20 minutes. It was not very cold when I left home. Once in the field, a bit of warming up with old friends before going towards more challenging targets. The conditions were certainly not the best due to the high Moon in the sky. However.. why not doing something a bit unusual? Just before leaving a soft layer of mist was rising from the field. My bike and telescope were both frost on the surface (not the optics!). Cycling back home when frozen is not really a pleasant thing, but the memory of what ju

  37. Ok had a little time to play with the data and have the following using large stack sizes (30% of 7200ish) and a 1.5x drizzle in AS!2. Firstly the reprocess of the original capture: Second a WJ Derotation of 5 successive captures with a slightly wider field: Slight fudge on Europa and Io to save time, but very pleased with the levels of detail and noise in the bigger stacks and derotation.

  38. Hello All, A few nights ago the weather forecast looked good; I managed to open the obsy up and start everything up at dusk, and get on-target as the last vestiges of twilight slipped away. Up until now I've been playing around with imaging - mainly M42 and the moon - and I'm still at the low end of the learning curve. This time I thought I'd give M81/M82 a go. It's the longest imaging run I've done; the weather forecast was good and I risked leaving everything running as I went to bed at 2 am. The clouds rolled in around 4 am, mercifully without the rain. I feel like I learned more

  39. I've really enjoyed reading the thoughtful input to this thread since I made my rather plaintive opening post. Thanks very much for bothering to post your thoughts - much appreciated I have no complaints at all about the performance of the Ethos and XW eyepieces that I was using last night - they showed fantastic views of both the lunar surface and Jupiters splendour. The level of detail was as high as I've seen at any time and they are a pleasure to use. My surprise was in how close the low cost eyepieces were to the on axis performance of the "exotica" although as has been said, vi

  41. Sorry for late reply. The mount doesn't turn in either axis without the motors turning them unless i push it hard (which I'm afraid to do). It's probably a good idea to do the alignment with the camera in, but that doesn't fix the balance issue. The problem is the camera is very heavy and it pulls down on the back end of the scope. I don't have a very long dovetail bar so i can just slide it to balance. I thought of just adding weight to the other end of the telescope to fix the balance but Im afraid to exceed the limit of the mounts carrying payload. Everyone was mentioning how thi

Those pics are both taken with a cheap microsoft life cam that I ripped apart and just glued a filter thread onto, which then threads onto the lower metal sleeve of an eyepiece, then just fits onto the telescope. This is taken directly with the webcam plugged right into the telescope, no diagonal, or barlow. I've got some new eyepieces and barlow lenses coming in the mail, but haven't got them yet This is the webcam I modified to take this picture. It's a start, I'm actually just gluing the new adapter onto my car dash cam and will be testing that hopefully tomorrow, or whe

  45. BIG, Big thanks to Damian and Vicky for this afternoons outreach event at Middlestown school. It turned out to be really enjoyable. I thought the kids were going to mount my scope at one point and start riding it around the hall!! ?? Seriously though, thanks very much. We definitely stirred a lot of interest in the hobby and in WADAS. We may even have a few potential future members. On of which has just bought her 22 year old son the same scope as mine and it sounds like he is very interested in joining us, so let's hope he does. ??

  46. Assuming that your goto gives consistent results - try goto on some named stars such as castor,Pollux, Polaris, Rigel - the objects should appear at same location in your eyepiece field of view (may not be the centre but should be the same area of field of view each time). ...now goto a galaxy of your choice (m31, m82, m81) and look to the same area of the field of view in your eyepiece... you should see a faint smudge? Or maybe the MOON could be your issue, it is best to try galaxies on a moon free night, they are faint objects? hope this helps, Alan
