  1. I have struck apon a conundrum that affects us in the UK more than most, due to the shortness of our weather windows when doing DSLR AP. I just had my camera in the fridge overnight to create a set of BIAS and DARK frames at 15C sensor temperature. When I am taking 180 sec exposures over say 3hrs, to keep the sensor stable at any given temperature I need to insert delays. I have roughly calculated the deltas based on some timings, I still need to do further testing to refine these. - 30 Sec gives me a delta of + 12C - 45 Sec gives me a delta of + 10C - 60 Sec gives me a delta of + 07C So this beg the question, with our weather limiting the time for exposure, is it better to get a set of images say 60, at a range of temperature (12C - 20C) or less lights say 45 at a stable temperature 12C? I am sure there is some SNR that can help to determine when it is better to just capture lights say 20, whereas if you have the above scenario, it is better to sacrifice some lights for stable temperature and less noise.

    Taken at 10C, unguided, but well polar aligned. 120 Second subs @ ISO800 10 min stack.
  3. Hello, I have taken my first steps into DSO Astrophotography last night. It was a bit frustrating as my Polar alignment can really do with some work. I tried to drift align, but I think I just made it worst Anyway I had to reduce my exposures to 120S from 300S and then it seemed stable enough. I captured 8xLights and 4xDarks @ ISO800, 120S, F4.75 (i.e 378mm with my 80ED, used a reducer / flattener) I have still had to crop the image down to size a bit as the corners are a little dark / odd. Stacked in Deepskystacker and then edited in Image analyser - I think I have over processed abit I really want to extract more of the nebulosity, but not sure how to. Anyway enough faff heres the image (Png has been reduced to 3rd of Size) I have two ISO1600, but they are quite washed out, not sure how to use these. 4 of the 8 iso800 lights are best contrast, so might restack with just these. Anybody have any idea on how to use the star mask in DSS? Any comments / suggestions welcome.

    Final attempt at M45 until I get more data, when the weather clears.
  5. Well i actually managed to get out last night for a short time, i would class it as a clumsy night managed to bump the scope twice and had to re-do the alignment, it was so cold all my fingers felt like thumbs Anyway i eventually managed to get 3 x 5 mins exposure on Rosette with Skywatcher 130P-DS Canon 600d (unmodified) Iso 400 PHD2 (still not figured this out yet) also had the Baader UHC filter left on the end of the nose piece (forgot about that) so not sure whether this helped or hindered? any hints/tips welcome to help me improve on this, Thanks for looking,
  6. Hi Stargazers, After a lot of work and help from the great Damian Peach I managed to get some really good images of Jupiter Mars and Saturn despite a total spend of just £100... and I made another bonkers Astrobiscuit video about it which I hope you enjoy. Mr Peach really helped me pick my nights to image and the other big surprise was how good the canon 600D is at planetary. All comments/ advice/ criticisms most welcome...
  7. Hello there, for a long time now I use a 600D now for AP, but I want more out of it. Since I am good with electrics and stuff, I want to modd it by myself. So what is the best way of modding it? Remove the ICF and the IR cut filter and what then? Using clear glass or just leave everything out of it? I dont need the cam for daytime, its just an astro tool. Thanks for suggestions. Alex
  8. Hello world, When I first got into Astronomy in August last year, one of the very first DSO that I looked at was M31. I was a bit disappointed in what I saw at the eyepiece, especially when I compared it to the images that I had of the galaxy. I decided to take the family on a holiday to a dark sight in Brittany on a holiday, to see if I could get some pictures. When I plugged my old 350d onto the back of my 127 Mak at the time and took some exposures, I was expecting to stack them and see something amazing. What I saw was not that much better than what I had seen from the eyepiece. At this point I almost packed in the whole gig and put all my kit on ebay. I sold my camera, and my alt az mount, so all that I had left was the Mak (which I later used to some good effect on planetary) Anyway, over the last year, I have given a renewed vigour into Astro and purchased a EQ5 mount and a 80ED. So when M31 cleared the trees last weekend, I thought that it was time to take on my Nemesis. Not wanting to take any chances, I did exposures at multiple lengths, from 30sec, 60sec, 120s, 180s and 300s. This way I had a variety of exposures to play with to control noise versus the luminosity. The final recipe has been to use the 180s and 300s exposures for the lum and the 60 sec for the stars and the core. This has been a bit of a processing marathon as the combinations available are numerous. I have downloaded some new processing actions and been doing research on the net. This is what I have achieved to date on the processing, with some real noise issues (summer temps still high for the UK.) I have seen better, but this is pretty special to me as it has been a massive learning curve over the last year. Let me know your thoughts, experiences and advice, tips tricks etc. Or post your images of the subject, especially if you have been through the pain of using a DSLR. Thanks for looking, dark skies ahead!
