  1. Here is my first effort at processing the vast amounts of data from Friday night at Kelling with some lovely skies for a few hours. TS60ED with an ASI1600 on a StarAdventurer. 229 x 30 seconds L and 90 x 10 second for each RGB, binned 2x2. Turned out rather nice. I threw away an awful lot of clouded out Lum subs, but my laptop was rather glad of that.

  2. Working on these two. First up is a straight Lum channel for M31 (Andromeda galaxy) - this is what I collected tonight 11 x 900s, but it's less than half the total if I include last year's data so I will try stacking them all together and see what comes out Usual kit: NP127is, Moravian G4-16000, 10-Micron GM2000HPS, Chroma 3nM filter (for Ha) Full size: http://s970.photobucket.com/user/ChrisLX200/media/Astro - Images G4-16000/M31 Lum ST_zpsiyxgriii.png.html Second is trying to see how deep I can get into gamma-Cass nebula, currently 10 x 1800s in Ha.

  3. With the lack of any really exciting activity and some decent size gaps in the clouds, I thought I would finally have a go at "proper" mosaic. I have been doing mostly 2 frame mosaics mostly due to the thought of the time involved in a 16 frame one. I decided to restrict the individual runs to 1,000 frames which take around 25secs to take. So 16 of them is around 8 minutes and the gaps looked big enough for that. The usual set up Lunt50mm D/S, dmk21AU618, plus my x2.5 Powermate. Stacked in A/S2, then sharpened in imPPG, coloured in C/S2. Absolutely delighted with the end result to be

  4. well this is the first of my winter targets and the first with this widefield set up- 1200d unmodded and super-takumar vintage lens i got off Chris "thanks chris". 15 x 45sec shots on the wide on and 10x 60sec for the smaller. iso 800. im still learning how to process these widefield jobes, but am quite happy with how thay have turned out with a unmodded cam. i might get another chance tonight if the skys keep clear. thanks for looking and i hope you have clear skys. charl. its hard to judge how much black to clip same image but slighty diff colour but the black clipped more an

  5. Two nebulas from last night. After seeing the narrowband Pacmans just posted by toxic and others here, my RGB version looks a bit pale, to say the least, but I am just happy that the sky is dark again so I cannot stop myself from posting. I got my Sky Quality Meter out last night and it showed 21.2, so I cannot complain about light pollution. However, there were some haze that affected the resolution of my images and issues with the autoguiding. ES 127ED on an EQ8 in obsy with finderguider, Canon 60Da at ISO 1600. Pacman: 18 x 8 min. Iris: 11 x 8 min (then the haze killed the session)

  6. Thought i would get the LS35 our today and see what was going on on with our nearest star. Mainly watched a prom on the western limb most of the afternoon. Managed to get a couple of minutes of video with and without barlow. Nothing like as good as some of the solar images on here, but i am still happy with the little LS35. Thanks for looking :-)

  7. Well....I ground and polished both mirrors. The 10" primary was 19mm thick mounted with three silicone blobs onto an MDF board. The MDF mirror board was pivoted at the centre on a coach bolt and three bolts and wing nuts took care of the collimation. The tube was rolled galvanised steel sheet from a local ducting manufacturer and powder coated on the outside, black spray painted on the inside. Early ones had a single vane secondary mount while later ones were 4-vaned. The focuser was normally from Irvin's but your focuser looks more like a Celestron unit which I did use between supplies of Irv

  8. Here is an unguided image made possible by the ASI1600. M31. 229 x 30 seconds at unity and 90 x 10 second binned 2x2 each RGB for under 3 hours total. TS60ED on a StarAdventurer. Amazing what can be done in quite a short time (ie 1 uk night) with this camera and a setup to take advantage of it.

  10. I've been hopeful of getting out while the moon is well away but the past week has been difficult with clouds and rain. 4am was quite clear and stars were shining brightly so I quickly pulled out the 152. The air was fresh and clear with a number of tumbling white clouds moving at speed. However there were big enough gaps to make for a fine session under skies as dark as I can get at home. M45 Pleiades A northerly breeze was a fair compliment to the brilliant glow of the Pleiades, framed well in 2.8° and looking pretty spectacular even in the 50mm finder! Naked eye I could make out

I love my frac but you cant beat the stars on a reflector... Thanks for looking... p.s. looks like you can see the focuser shadow on the large star halo's, is the anything that can be done about that?

  14. I've wanted to image this jewel for many years. I decided to visit an Astrofarm in Namibia, and finally got the chance. Taken with a Canon 200mm f/2.8 at around f/4.4. This is 4.5 hours of 15 min subs. This is a WIP as it's a tricky target to process. It has very bright areas, so it's a balancing act trying to dim them down slightly and getting some detail, while still keeping it natural looking. I'll no doubt be tinkering with this for a while I do have Oiii data as well, but I bought the filter just before I left (Baader 8.5nm), and it turned out to be part of the batch affected by the

  20. Hey all, Here's a look at the Pleiades last night. Canon 7d, 400mm at f5.6 ISO 1600. 15*2 min 6*5 min This focal length is starting to test the mount, plus it was a bit windy, so I threw away around 20% of the 2 min subs, and nearly half the 5 min subs (unguided). Beautiful target though.

  21. Ok a memorable night for all the wrong reasons. Session planned with a few others at a dark site, all keyed up and good to go. Start off, forgot my boots and my viewing list. Got there and found a bearing missing which mounts the pushto bush so that wasnt working. Some people arrived and couldn't get thier car lights to go out until they timed out after about 20 minutes. All later arrivals never thought to go to side lights for the last part and just take the time. Rather annoying. Cloud lingered longer than forcast but I Did manage to get M33 which was nice but thats the o

  22. After getting a bit annoyed with the focus rings on the kit lenses that came with my Canon 100D, I thought I would buy some cheap old M42 lenses from eBay. I have bought a 55mm F/2 prime and the 200mm prime that I have used for this shot of M33. The 55mm (a Super-Takumar) is stunning for widefield but I have not done any serious work with that yet. However I thought I would have my first go at M33, noting that it is not very bright. The following is the result of 40x120s Lights, 30x darks and 30x Flats taken whilst mounted on my Star Adventurer. Stacked in DSS and then processed in StarTo

  23. Hi My ASI1600MM-C arrived and I got a clear night on Thursday so managed to use it in anger. I lost most of the evening to non-camera related issues so only managed to take usable images of M45. With 30s subs, I captured 15 mins of L and 5 mins each of RGB at a 300 gain. This was my first attempt at LRGB imaging and I have a few questions - not all camera related. - I set cooling to take 2 mins. Is this too fast? Will the speed of cooling need to change depending on ambient temperature/humidity? - I'm using SGPro on trial as previously I was using BackyardEOS. In its frame/focus

  24. It has been too long since I contributed anything to the forum, so I thought to share with you my latest try in planetary astrophotography. Actually it is my first try with SW 300p Goto Flextube dobsonian which I recently acquired. I wanted to try out how the system tracks for webcam astrophotography, which is my second point of interest after visual observing. In short - it tracked quite well - no jerkyness in tracking, very smooth, stable and centred for a long time, and I am also very happy with my old motor focus which helped me out tremendously. The conditions were very poor though,

  26. What Does a Starfield Hide? I am experimenting with using the multi-spectral feature of StarlightLive to capture wide field images of the sky and also display the H-II regions of the same areas. I would have liked to continue with this thread, where I left an earlier thread near the Pipe nebula area in Southern Ophiuchus https://stargazerslounge.com/topic/265965-from-winter-towards-the-summer-along-the-milky-way/?do=findComment&comment=2912530.

  30. Recently some of the best nights have been on Sundays, which is a bit naughty before a week at work but also a great way to unwind and clear the mind and it’s on that basis that I justified putting the scope out late this afternoon ready for a session this evening. After a great session last Sunday on some doubles in Delphinus, I’d earmarked tonight for a deep sky tour of the dolphin followed by some indulgent galaxy hunting in Pegasus. Interstellarum was my companion. As the last signs of twilight dipped to the west, my first target was NGC 6950. This was a loose and uneventful open

  31. Hi SGL, I had a very successful Summer holiday at Ollys, where I began collecting data for Mosaic number 3. While we also captured some single panel shots, the main part of the work was done on the Dual Tak rig. At one stage we did have 4 cameras running, although one was just piggy backing on a mount taking DSLR widefield shots, so I was able to let it run on infinity focus, and no guiding or PC involvement necessary. Anyway, I collected 100 hours of Luminance in a 5x5 panel 530mm format. I gave more overlap than I had previously, as the Cartes Du Ciel program looked like I could ge

  40. Well, all is not lost. It's still broken but repairable. It looks like I miss aligned a tape wire, worst case new PCB, best case new tape wire. Wire kit £30 PCB £65. It will work again. Could be expensive mistake but it can cost a couple of hundred to get it modified anyway In the meantime I bought the wife a new DSLR today with my scrap copper haul ( I'm a plumber by trade ) Forecast is for clear sky's tomorrow night so I'm going to try her new camera.

  41. I had a chance to gather some OIII data for the veil i started in HA the other night. Stars still aren't perfect but i am not super concerned with that at the moment. Have some issues to work out on the mount. So this image was processed in Pixinsight and finalized in Photoshop. I processed each separately and them combined them with LGRB Combination, 50% HA and 50% OIII as a LUM, HA as Red and OIII as BLUE and Green.. The only thing i did in Photoshop was contrast, saturation, and a small sharpen on the outside edges of a few things. Hope you enjoy! 17x600s HA 19x600s

  43. This is my second deep sky image with the baby tak on the sky adventurer and my first of M31. Considering what the lights looked like I was surprised at the end result. I stacked 34 thirty second images taken on ISO 800 and calibrated, integrated, and processed them in pixinsight. I think more lights would have been good but for a 60mm scope it's picked up a lot of data. All suggestions welcome

  44. I've reprocessed the stacked image using a masked stretch, followed by a light stretch with histogram transfer then HDRMultiscale transform a bit more aggressively on the core. then combined it with the original image using pixelmath. This was a bit of trial & error as I didn't really know what I was doing but it seems to have worked. The core is much better and the overall image is a bit softer.

  45. Having been part of this project I thought I would mention a few points. Moonlite / Ron were aware of the issue for more inward focus, and it was a discussion point during the planning and design process, however it was made as short as it could be. I am guessing the worm gears etc take up a certain amount of the profile leaving only so much room for the rest of the hardware. Maybe someone contact Ron and see if it could be at least in theory / on paper have some tweaks to achieve a variant that gains the desired in travel, there may be a solution !

  46. I had my first opportunity last night to try out my 14mm XW that I bought second hand over the summer. I noticed the Pleiades was on view and although it wasn't high, i set the scope up on its AZ4, inserted the 14mm XW and WOW! I wasn't dark adapted and the scope was warm yet the nebulosity was the first thing that struck me. It wasn't just visible around the brighter stars but the whole cluster was swaithed in a wraith like mesh which was easily visible. The Pentax XW's are a perfect match for my small refractor and although the 14mm has received mixed reviews, i found no fault with it. To ge
