  2. LRGB and Ha The Horse Head Nebula In Orion. Imaged with the 12.5 RCOS @ f9 and FLI 16803 36x 600 in Luminance and 12x 900s in each RGB total 15hrs. High haze effected some of the data but the weather in Spain hasn't been at its best. This scope I did a complete strip down and refurbish including a nice shiny recoat of it's stunning Zerodur optics ...that was a very nerve racking day I can tell you. Thanks for looking… Peter Shah

  3. All, my first colour mosaic, a lot of challenges and issues with capture, clouds, orientation of panels etc..

  4. M31 was the object for my first light with the RASA 8 and ASI2600MC back in August. Last night I finally got around to collect some Ha for it. Collected with a dual band filter (IDAS NBX) but I only used the red (Ha) channel. The data was added to the red channel in the RGB image as blend mode Lighten in PS. I think that the Ha clearly lifted the colours of the galaxy in a pleasing way. For the RGB data I have tried to tame the enormous dynamic range of this object so I could both bring out the outer dust "cloud" (presumambly made up my stars) that is often missed (or outside the FOV) as

  7. I hadn't been expecting a clear sky last night, but we got one for a couple of hours that gave me the opportunity to quickly set up the Star Adventurer in the back garden. It was a little hazy, in Bortle 4/5 skies, but I managed 76x 1 minute subs with my Canon 6D and Samyang 135mm lens at f/2.8 and ISO800. I captured some darks and flats too. Stacked in DSS and processed in Photoshop. I would like to go deeper on this object, particularly for the "muckiness" in its locality, but as a starting point I'm reasonably happy. Deep sky isn't something I've done a lot of, but it's nice

  8. I have to admit that I knew little about Astronomy Now until @ollypenrice asked me if he could use my Squid image to illustrate the possibilities of the new generation OSC CMOS cameras (ASI2600MC in my case) in the January issue. One bonus for me was that the magazine sent me a free issue and I liked it a lot. I also noticed that they had a gallery section, so I though why not give it a try. Apparently they liked my image so it is now in the March issue and they gave me a 15 pound voucher. I have now spent that and a bit more on a yearly subscription (after Swedish customs have ensured me that

  9. This is a target I first saw last year, and , well, just fell in love with it. I never thought I could ever get it other than through a paid subscrition to some set up high in the Andes somewhere. At the end of January though, I was delighted to find out I could just about do it from my back yard in SE Spain....if I was prepared to go 'low'. Working at under 28° altitude (as and when possible over the last two weeks) I am delighted to have got this target . (I may yet try improve on it - but that wont be a big change and it won't be anytime soon).

  10. Can't really say this is a shot of M81 and M82, although they are both smack in the centre of the field! Ultra wide field Integrated Flux Nebula around M81 and M82. Imaged from Spain with the 105 sigma Lens and the ZWO2600 OSC, 5hrs total exposure, 300s subs. I've also reprocessed my old data set taken with my AG12 from the UK, I merged the two to bring out some colour in 81 and 82 Thanks for looking Peter Shah Reprocessed version with better star colour and background contrast showing some of the fainter stuff Original Process

  13. This time last year whilst on a dark sky skiing holiday I remember looking at the Rosette thinking how amazing it was and that I'd need to image it again. Ive had to settle for roughly 2hrs on each channel as the weather gods haven't been kind recently! Thanks for looking, Ken

  14. The weather has been absolutely shocking here in the NE since christmas. So when I had a clear window of about 2 hours last week I took the opportunity to try and grab an hour on M42, in the end I ended up with 18 x 2.5 minutes subs. So here it is: Stock Canon 80D and SW 72ED on HEQ5 Pro No filters were used and the image was taken from my Bortle 8 garden.

  15. Whilst waiting for clear weather, I decided to reuse some data that was previously acquired by my Skywatcher ED80 and my Esprit 150. I used the Esprit data to get maximum detail on M106 and its companion NGC4248, whilst I reprocessed the ED 80 data such that the resultant background showed very faint objects. The ED 80 data is LRGB whilst the Esprit data also contains a Ha blend into the red channel. On the processing side, I used RegiStar to align the Esprit 150 and ED 80 images and then used Pixinsight's Gradient Mosaic Merge to create a seamless image. Alan M106

  16. Hello all, Sharing with you my first DSO mosaic image. This the Large Magellanic Cloud visible from the southern hemisphere, a companion/satellite galaxy of our Milkyway 160,000LY away. Due to the angular size of the LMC, this image consists of 4 frames, each exposed in natural color at 500mm focal length through an 80mm refractor. The 4 frame are combined into one image to fit the whole satellite galaxy into the frame. The camera used was my astromodded and active cooled canon 40D. Exposure time was 2 hours and 42 minutes per frame for a total of 11.5 hours for the whole image.

  17. For me- this was a hard one....so I am not sure how it will go down. I tried it in January and gave up (even though I obviously kept the data). Again now, very recently, I went back to it until the weather (humidity mostly) has put a stop to any imaging once again. Last night though, I actually combined the Jan & Feb data - even though the imaging scale and the camera rotation had both changed considerably. APP did a fantastic job...bringing everything together ..... and then with quite a crop....I came up with a result. (Total time: 23½ hours). More details & larger image @ https://

  18. I don't know if this would be considered as cheating on another level, but here I go:) Since I also have an interest in weather satellites and radio astronomy I regularly receive weather images from Russian, European, Chinese and American weather satellites. Some time ago I became aware of a European satellite imaging the sun in extreme ultraviolet and dumping the images when in range of Belgium (location of headquarters). This is all done at a frequency of 2235MHz and can be received with moderate equipment. Here is my first image received from the Proba 2 satellite The noise i

Imaged through my Esprit100/SX46 GT71/ASI1600mm over 9 sessions between late November and early February. 3hrs Red, 2.5 hrs Green and Blue, 25hrs Ha (as the moon was virtually ever present when it was clear) and 3.5 hrs Oiii.

  20. So after 7 weeks of unremitting cloud I finally got the new camera outside. for all of 90 minutes before Orion started to get too low and clouds started to build again. But at least I got an image. This is 15 each of 180s, 120s and 60s. I did that partly to get a handle on how the camera performs and of course to try to get some detail in the core. SW 80ED, NEQ6, ASI2600mc pro, L-eNhance It is stacked in APP using the Ha-Oiii colour algorithm then a very quick hash through in Pixinsight. Overall I'm pretty happy with it - a bit grainy when you zoom in hard and I'm not sure

  21. Finally got around to processing my attempt at a Mars animation from all the way back in October, Would have gone on longer but was interrupted by cloud. Think that was what put me off, thinking it was incomplete. Turned out well though, for a first attempt, some frames were awful but I have included a couple of the frames that look really good. I know that the south pole is at the top but it just didn't look right the other way around! Taken with a asi120mm through a C9.25 with best 50% of 10000 frames in each RGB channel. Mars Oct 2020.mp4

  22. A family social "zoom" call was scheduled for yesterday evening and of course it coincided with the first clear skies for a little while. Family has to come first though so I popped a scope (my Vixen ED102SS refractor) out to cool down early on and got on with the virtual socializing. By the time I was able to get outside, the moon had dipped behind our house and Orion was well across the sky as well. I could see that the transparency was not the best and it got worse as the evening progressed, unfortunately. So, as pushing for the more challenging DSO's was probably not going to pr

I've lurked around on this site for a long while and always found it to be immensely useful and entertaining, however being a bit of a natural introvert I've never really posted anything until now. -I'd like to change that and not have another year of self-imposed isolation! The weather promised to clear on the 23rd and 24th of Jan, and luckily enough for me they were not wrong!

  26. Another clear night and with the moon no shinning much, I was out looking for some DSOs. I got out just after 10 with my 8" Dob and since I had not spent much time observing the North I decided to focus on DSOs around the Ursa Major. As a beginner it was my first time to put a plan together, last minute since the weather was rubbish with rain all afternoon, of targeting a narrow area of interest. I adapted my eyes in the warmth of dark sitting room and the night sky was glowing with stars (I think the rain had really cleared the atmosphere). As many of you know, although a beginner, I am fasci

  27. Last week saw some clear skies, even though the Moon was a bit on the bright side, and I managed to get in some imaging time with my new camera. I'm still very much new to the CMOS OSC camera so more time is needed to fine tune the settings. This is the best of the weekend's images and is 68 x 180 second subs at 120 gain, using flats, dark flats and darks. Stacking in DSS with post-processing in PI.

  28. This is a two panel mosaic where I used one of the panels from my recent mosaic, containing Barnard 14 (with IC2087), and added a new panel (the bottom half of the image) dominated by Barnard 18. These nebulae belong to the Taurus Molecular Cloud. 12 hours of total integration time with the RASA 8 at f/2 brings out quite a lot of light and colour even in dark nebulosity. Imaged 10 - 14 Feb with the RASA 8 and ASI2600MC (gain 100) without filter. 180 x 4 min. Stacked in PI and processed in PS and PI. I also post an annotatded low-resolution version grabbed from Astrobin. Fro

  30. To think I came close to selling this fine telescope (Bresser AR 127L) when all I needed to do was buy a Geoptik Nadira Observing Chair! Makes it really easy to use the 'scope at high altitude - the lowest setting is about 23cm. Fabulous bit of kit, with six positions in total, nicely made, sturdy, adjustable and comfortable back, and so easy to move the seat - it simply slots into the holes in the back. So now the slow, long focus frac is not only easy to swing about on the Skytee II, it's also a joy when used over a wide range of altitudes. Great 'scope, coming in for a lot mor

  31. Work has been pretty hectic lately, and with the weather as it is there have been limited opportunities to observe. Tonight, I was not expecting the clear skies that treated me as I stepped out to put the bunnies to bed, and the crescent Moon looked lovely low in the West. Thinking that I would miss the chance, I then remembered my Unitron AltAz mount and the trusty Telementor. This was all pretty quick to setup, although I had to mess around a little to reach focus with the Leica Zoom, finally screwing it directly to the prism via the T2 thread to shorten the light path enough.

  32. I finally modded my 550D last week, so this is also my "new first light" with it. 78x 180s exposures at ISO 800, and i mixed in some Ha from a stack of 16x 600s at ISO 1600. Captured with the Explorer 200. Was struggling a bit with light pollution, but didn't feel it was bad enough to throw in the CLS filter, and i think it turned out quite OK after all.

  34. This is a two panel mosaic of dark nebulae in the Taurus Molecular Cloud. The relatively long total integration time at f/2 brought out quite a lot of colour and dust. The nebula to the left is Barnard 14 (containing the bright IC2087) and the one to the right is Barnard 10. The long stretch of dark nebulosity at the bottom right is NGC1539. From Wikipedia: The Taurus Molecular Cloud is a molecular cloud in the constellations Taurus and Auriga. This cloud hosts a stellar nursery containing hundreds of newly formed stars.

Lum 32 x 3 min RGB 13 x 3 min each I currently dither on the RGB scope every 3 subs so I'm dropping 1 in 3 Lum subs, but I will try pushing this out to 1 in 4 or 5 as I couldn't see any appreciable walking noise in the final image. Calibrated and stacked in APP, processed in ST 1.7 and AP, I ran it through the PI image solver and annotation scripts to try and identify the numerous background galaxies, but it missed quite a few.

Ultimately over (too) many evenings, this is a four pane mosaic of LDN1495 taken with my multi-scope-wide-field rig which was pulling in three times the hourly rate of data. Approx 50 hours of Lum data and 40 hours of RGB were used to tease out some details.

  43. Hello again, As the galaxies are starting to get higher in the sky, I started to point my telescope a bit more towards them. The first that I can say I have enough data to produce a decent image is M106. Because @wimvb pointed out that my M97-M108 photo had some objects that are very far away, I took the liberty to go online and try to find how far some of the objects in this photo are. I was quite shocked to find that I captured a 19.5 magnitude quasar, 7C 121446.70+472852.00. I added it in white writting to the annotated photo and I also cropped a part of the large photo to sh

The middle panel is a short exposure which roughly corresponds with the number of stars that can be seen from a truly dark site. The right hand panel has an hour of H-alpha data blended in in an attempt to show the sheer scale of Barnard's Loop and the Angelfish Nebula in the sky, although it's not possible to do it justice in a photo. I also put together a version to support the CPRE 2021 star count.

I decided on trying to capture a video of me shooting the Orion constellation in the given window of time using my small setup, an AZ-Gti and eq wedge, canon 700d (modified) and 50mm f1.8 lens. - I also leveraged use of an Optolong UHC filter to try and cut through some of the light pollution.

  49. Hi, As a regular reader of the SGL forums, I thought it was about time I introduced myself and started to contribute. I only got into astronomy / imaging last year having purchased a 200p and HEQ5 for visual use in January. Although I always had imaging in the back of my mind, the idea was to spend a while observing then think about further kit. Anyway, that was the plan..... 1 year and a small fortune later I am now completely hooked on AP. I now have a SW ED80 DS-pro, an ASI1600 and EFW, an RC8, AZ-EQ6 and a cupboard load of other stuff. I am currently waiting for my Canon 600

  50. Last week I posted up the arrival of my new WO ZS73 II. Today my Ioptron CEM26 arrived. I opted for the literoc 1.75” and Ipolar. I am well chuffed with this mount and tripod, even has its own built in anti vibration pads and is very well made and pretty sturdy. The mount looks rather unusual compared with my previous CGEM and HEQ5. But it certainly looks very well put together, it’s very smooth and very quiet. Just waiting for the arrival of a clear night now.
