    DSLR M31

    Hi All, Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.

    Andromeda (M31)

    Never had much luck with this target, however last night (11/09/2016) the conditions were quite good what with the moon setting around midnight, relatively clear skies and M31's position in the sky. I managed to get 8x600s subs before the clouds rolled in - considering the relatively short integration time I'm quite pleased with the result and plan to grab more data as and when possible. Shot under dark skies from Surprise View Car Park in Derbyshire with QHY8L, SWED80, HEQ5, Orion SSAG. Processed in PI and PS. Thanks for looking! Rich

  8. From the album: Learning to use my kit

    This is the first test run of my finder guider set up on my Skywatcher 150PL and EQ3/2 Pro. About an hour and a quarters worth of exposures at ISO1600 (just thought I'd try the higher ISO) with flats. darks and bias. About 30 minutes of 5 minute subs, the rest made up of 3 minutes and 1 minute subs. It seems less noisy than my other M31 unguided attempt. Hopefully the images will get a bit better as I get use to the guiding system.

    M31 - Andromeda Galaxy

    From the album: City View

    This is M31 - Andromeda Galaxy. Another nemesis of mine. This one was a battle as I struggled to get my Canon 600D to image anything I could use. The camera was fine, but I struggled with dew, focus, guiding etc. And I didn't know how to take flats, so this lacks all calibration. The colours are a bit off, but it's my first guided image and I'll keep it as it is as a fond memory of the early struggles. HEQ5 SW120 Canon 600D SW ED80 and MS Webcam guiding 248 minutes in total, and I think 2 minute subs. Edited in Canon Utilities
  11. I currently am on holiday in my father's hometown, a small island near rhodes called symi.Symj, is a pretty small town,with only about 2000 residents.That means that the light pollution levels must be low. Acknowledging that, i called my friends, grabbed my 10x50 bins(that i got for 20€ from Turkey),and went on my way to find a dark site.About after 20 mins of walking (from the city),i stumbled upon a beach, it was dark, so i went in.There i decided to lay on a sunbed that was there.After looking up(not being dark adapted, my friends just kept turning their flashlights on for some reason), i saw the haze of the milky way stretching from Cassiopeia to cygnus and beyond!I was amazed as i ve never seen the milky way before and smudged it off as clouds until i confirmed it was the milky way from an app! The weird part was that at just straight overhead, was the port ,which had many lights, and as a result the sky appeared half bright and half dark. I turned over at Sagittarius and headed over the lagoon nebula. Brilliant! 3-4 stars in a line surrounded by bright nebulosity.(while still being in the haze!) Afterwards i headed to cygnus,it was a real light show! I saw the milky way layering on top of Cygnus while catching a glimpse of m23 and yet again, failing to see NGC7000 . Then, with the corner of my eye, i detected something moving, then turned over to Cassiopeia to see a shooting stsr!(it was my first time seeing one!!!) Was very brief, yet enjoyable. Right afterwards i turned over at the Perseus double cluster.Magnificent! Appeared as 2 small balls of light , almost connected yo eachother. Finally, i realised that finally, the target i was seeking to observe all year long, M31 was into the area with the light pollution! What a shame! While also being low on the Horizon, I couldnt see it with the naked eye. I observed it with ny binoculars for 10 minutes or so . The core was resolved nicely with some hints of outer nebulosity. Overall a great night and now, i wished i had my 8" dob with me.... (Sorry for any granmar mistakes, im currently typing this at 2 am xD)
  12. Hello, This is my first astrophotography with my own scope (and first light for this scope). I've always been fascinated with this galaxy, and it was my childhood dream to capture it. It finally happened ;-) You'll find all the technical details on the description on flickr. Overall it's the first light of my skywatcher Quattro 250mm/1000mm f4, NEQ6, with an unmodded Canon 6D. Integration time: 1h59 Processed with PixInsight. link to flickr for the full resolution and description:
  13. One of my favorite deep sky objects in the night sky, the great Andromeda galaxy. All the processing has been done with Pixinsight. The scope was FSQ-85 with the good old unmodded Canon 6D. Around 5 hours of data with 5 minutes exposure. Hope to add some short exposures to the core someday.
  14. This imaging session, occurring over 2 nights was not without its mistakes and confusion! Setting up the first night I seemed to spend most my time trying to remember how to configure the capture software correctly. The second night I decided not to connect the guide camera to the PhD Guiding 2 correctly and spent 30 minutes establishing that fact. However, out of the jaws of chaos (which extended to the processing of the image) came one of my better efforts on this object. It’s also the largest amount of data I’ve collected with almost 5hrs going into the can for processing. Details Object name Andromeda Galaxy Object ID M31 Date(s) 11 and 12 October, 2017 Telescope Altair 115mm Camera ASI1600MM Luminance 89 x 2 min = 178 min or 2.96 hrs Red 16 x 2 min = 32 min Green 21 x 2 min = 42 min Blue 19 x 2 min = 38 min Ha 0 Oiii 0 Sii 0 Total time 4.8 hrs Frames 0 Processing PixInsight / Bias, Flats, Darks / Masked Stretch / Curves / ATWT I’m having fun zooming in to the different parts of the galaxy to view the H2 regions (star forming) that I was quite surprised to have caught in such numbers. These regions, swimming amongst the sea of big, hot blue stars destined to burn out quickly, are similar to our own Orion Nebula. Moving to the core of the galaxy and it super massive black hole the cooler, longer lived red stars dominate. Up to the left M110, another galaxy bound to Andromeda has resolved quite well – it can off look very pixelated – and nearby the big blue star who’s name I cannot find This galaxy is 220,000 light years across and contains a trillion stars which is twice as many as in our Milky Way galaxy. I think I now need a lot more colour data for this but its a start. David
  15. Hi everyone. I'm back, and trying again to get a decent DSO photo! This is my personal favourite so far, so I must be getting better! haha Still a long way to go with the processing skills, but I'm sure I'll get there. 23x Lights - 120 Seconds - ISO800 20x Darks 20x Flats (Yes! I've started to use these!!) 20x Bias Processed using Photoshop and ProDigital Astronomy Tools Hope you like it. Thanks, Mike
  16. I have been generally pleased with my Moravian camera and filter wheel. However, I noticed I was getting some very odd results when trying to calculate filter offsets for my autofocus routine. I found that the wheel was not rotating to the filter requested - indeed it seemed random. Of course it was not random .... I have a 10 position filter wheel. However, it seemed that the Moravian Ascom driver was convinced I had a 12 position wheel. To get the Moravian wheel correctly configured, you have to run a configuration program. It tells you to do this in the manual. I just hadn't read the manual. As you can imagine, this led to erratic results. If I shot filters in sequence, things would go OK. However, if I tried to go back to a filter I had shot before then it would not work. Now, I shoot the flats from my 7 filters all in one go, BUT I test out the required exposure times first which means a cycle through all 7. So when I come to shoot the actual flats, I am shooting through the wrong filter or (sometimes) through no filter at all. I was never all that happy with the M31 I did back in early December 2016. There seemed an odd gradient on the left side of the image: https://stargazerslounge.com/topic/282827-m31-revisit/ So, having got the wheel correctly configured, I redid the flats and recalibrated the data. Lo and behold, the bright patch on the left disappeared. Data: Baader Blue 36 mm: 16x300" Baader Green 36 mm: 16x300" Baader Luminance 36 mm: 61x300" Baader Red 36 mm: 16x300" Chroma Ha 3nm: 6x1200"
  17. ... I had decided to give up the hobby and recently sold all of my equipment, with the exception of an Equinox 66 with a dodgy focuser. When the bug bit again I added a secondhand EQ5 Synscan and a dslr, and had an evening of no frills unguided imaging on Wednesday. I can honestly say that I enjoyed that session more than I had in a long time, even though the results are somewhat poor! Barry
  18. Hi all, just posting some new pics I took the other night in Saint Barthélemy, at 1633 meters above sea level (very good seeing): M27: M31: IC1396: The usual problems arise: guiding, coma, and noise from the camera (especially visible in the M31, I think). These are pics from 30 73secs exposures at 800 ISO with darks and bias. I did not take flats... Do you think that would improve the noise problem? I'm hoping to construct a flatbox some time... And maybe acquiring a laptop to use for serious guiding. A guide scope would already be available from my astro club... Any thoughts, suggestions would be very welcome! :-) Gerhard.
  19. M31, reprocessed, 5 and 10m exposures 18 frames (don't know the integration time anymore, neither the no. of flats and bias I messed around with this so much).I decided to keep it real on this one (I'm won't to overprocessing in my light-polluted area, so I don't even lose one filament of detail). After changing the file name on the subs,(RAW to Tif), resizing and cropping, I made a gradient removing flat for each of them, and processed them normally after flat application / subtraction. I forewent chasing details in favor of nice values, such as RGB 23/23/23, or as near as I could come to when processing, to find a blend between detail and a pleasing view.
  20. More from my freshly modded nikon D5100, i think im falling in love with this camera M31 - Andromeda by Gareth Harding, on Flickr M31 - Andromeda Scope: Orion Optics VX6 with 1/10 PV upgraded optics Guide Scope: Skywatcher ST80 Guide Cam: QHY 5 Mono Mount: Skywatcher HQE5 Camera: Nikon D5100 Modded Exposure: 11x5 Minute Subs, Darks, Bias & Flats Technical: 750mm f/5 Software: DSS, Pixinsight, PHD, Nebulosity
  21. Hi, This is my first try at Andromeda with the SW Equinox 66, a SW LP Filter and an unmodded 1100D on an HEQ5 Pro with EQMOD. Camera controlled by EOS Utilities. PHD Guiding was with 50mm Finder Guider and QHY5. I used 14 x 5min subs with 4 dark and 22 flats. There would have been more subs if not for an unexpected meridian flip. Stacking was in DSS followed by (too much) PS processing. The LP filter controlled the light pollution but really extended the required exposure time. There are some interesting star shapes but no flattener could explain that. Apart from more data and better processing skills I am not sure where to go from here without spending a lot of cash. The most important thing was the great time I had collecting the data. Thanks for looking Barry
  22. Through a combination of work pressure and living in North Wales with its tendency to cloudy skies :-( I have not been able to do much astrophotography recently. Some quickly grabbed (and very pleasant) visual sessions, but nothing where I could take the time to get properly set up and collect some real data. In fact checking back my last session when I captured enough data to even play with was May 2013. Something had to be done! Nov 29th was predicted clear, no moon, I was at home and without an early start the following morning. So the best opportunity in a long time. Unfortunately, it was so long since my last session that I had forgotten a great deal and everything had changed. New laptop, new versions of most of the software I use, forgotten processign workflows and so on. It was almost like first light again. So I set up and polar aligned using my newly acquired PoleMaster. I have to say it is a great tool, and if nothing else stops you wasting an enormous amount of time. You know that bit with a portable rig where you are grovelling on your knees, cursing your creaking joints and squinting through the Dec axis to roughly point the whole thing at Polaris? Made more complicated in my case by wearing varifocal glasses so having to further tilt my head around to get the right bit of the lens looking up the axis adding creaking neck to creaking knees. Well it turns out when I started using the PoleMaster to polar align that I wasn't pointing at Polaris at all, but some totally different star! Doh! So that saved me considerable time trying to sort out polar alignment. I have to say the PoleMaster is a great tool and got me set up much faster than had been my previous experience. Probably nearly as useful for experienced astroinomers as for those who can't even recognise Polaris when they see it Then I found I could not get my guide camera to work, but after messing around for a while ended up with my Atik 314L+ as the guide camera and Canon 1000D as the imaging camera. I decided not to go for anything challenging; I just wanted a picture! So revisited M31 and M45. And here they are. About 50 mins on each. I know the focus is a bit off. I know the field isn't flat and stars are egg-sheped in the corners. I know I didn't really collect enough data. I know the processing is poor (desperately trying to remember all that ollypenrice taught me). I know that there are many much better images of the same targets in this forum. BUT I DON'T CARE!!! I'm back doing some imaging after a long break and learning how all over again, and if feels great!!
