First completed image inover a year and a half M31


Recommended Posts

First completed image in over a year and a half. I've started a couple of other projects but with work and the UK weather I've not been able to complete them. Anyway 90mins in Luminance and 30mins each in RGB taken with my AG12 and H35 starlight xpress.

Conditions were windy while capturing the RGB frames so not a perfect set of colour subs.

Any comments welcome

Worth taking a look at the full res....don't look too closely though as I have a very slight tilt on the camera

Thanks for looking

BTW just going off topic anyone off to the IAS next week?

Nice smooth M31 Peter, sounds like my imaging, just trying to complete my first serious attempt for 2 years and discovered a tilt in the imaging train somewhere.

Had a plan to go to Sixpenny Handley Star Party then IAS then SGLX11 but a wheel bearing went on the camper van and it's proving a nightmare to fix, may get it sorted over the weekend and get to IAS.

you're correct it is a great target both visually and for imaging.....good old faithful M31

I've yet to do it justice, but hopefully in a few weeks, when the earth moves my house out of the way, I'll get to have another go at imaging it myself.

Excellent detail to the core, and it has the unmistakable Shah Star Colour that I love. Some eggy stars in there as you allude to when seen at the full size.

Great work Peter.

Tom.

Thank you Tom. Yes the "eggy stars" caused by tilt on the camera and they all have pink tails caused by the wind gusting while capturing the green frames......seems to always be a compromise to deal with.

Easy enough to fix with the darken blend on a copied and "moved" layer.

Nice one Peter.....love this target...its a galaxy for god's sake!....still amazes me what we can not only see, but capture ...putting to shame the encyclopedia images of my youth captured with Palomar and Lick.   Glad you are returned....more please.

      Hey everyone,
      I was out recently in what felt like the first clear sky in years and got ~109 min of data on M31, minus 76 frames due to a 12mph wind, which left me with 69 min of data (each shot is 45 sec with ISO 200 tracked with skywatcher star adventurer). As mentioned in the title I captured all these images in a bortal 8 location, used an unmodified canon eos 400d and the skywatcher 75ed as the scope (with a flattener). I've attached my edit (warning: it is not great at all + slightly overedited to see what details are even there), and to be my surprise it looked very similar to an image of M31 with only 20 min of data which i captured a month earlier (both of which i used DSS and photoshop for). Now this may well have something to do with the way i edited it in photoshop or a different setting in DSS or just the fact that 49 more data doesnt make much of a difference considering im in a bortal 8 location, maybe you guys could help on that. I've attached the link to the original files (in the folder called 18.2.2021) as well as the stacked image from DSS (https://drive.google.com/drive/folders/12NT4TmLCXvTfOXNPE_l8UWPRpgO2VjLe?usp=sharing). I didnt capture any flat images but have dark and bias frames, all in their correpsonding folders in the attached link. It would be greatly appreciated if you guys could see if there is more data in this then i have managed to 'extract' using photoshop. (If you use different software and try and edit these files please tell me what you used) If there isn't then maybe do you guys have any images of M31 (or similar) from very light polluted skies that you could share here? (If so i would if you could share the full exposure time and gear that would be great)
       
      Many Thanks!

      So, although I had some issues with my auto guiding (which I found out afterwards) I did manage to get 9x180s exposures and 5 darks of Andromeda and give both stacking (using DSS) and processing (using GIMP).
      My first attempted DSO....
       
      I am pretty sure that people could get far more information out of the TIFF file from the stack.
      Hopefully I will get another clear night soon. I am in a heavily light polluted area so I do have a clip in filter on my DSLR which I think took a lot away.
      More practise needed!

      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.
