  1. I agree - I think my 1st attempt is better. Just thought I'd try to get a bit more colour into it but clearly I lack enough data. But this is a learning curve that "tends to infinity ". I'm learning all the time from everyone's helpful comments and aim to improve with each new data set I acquire. Thanks Lensman for your critique - it's taken onboard :-) Sent from my iPhone using Tapatalk
  2. I've finally got round to reprocessing the data with more saturation as suggested. Here is the result - I think I've gone too far though. I would welcome any thoughts and feedback ...
  3. Thanks for the tip Geordie MC - so it's more subs, more darks and more saturation. Thanks for all the help everyone. Things are starting to become a little clearer now Sent from my iPhone using Tapatalk
  4. Thanks glowingturnip - more subs and increased saturation it is :-) Sent from my iPhone using Tapatalk
  5. Thanks everyone for your support so far. Lensman - thanks for the advise - more subs it is although I might find 180 sec unguided a little beyond my reach. Possibly can stretch to 120 sec with good PA though. But I'll give 180 a go - gonna try to push the unguided to the max before I add more "spells" to my dark arts arsenal :-) Sent from my iPhone using Tapatalk
  6. Sorry - I know there has been a whole host of M31's over the last few weeks but I thought I'd add mine to mix. I know its not very good but it represents my 1st attempt at this object (and is only the 3rd DSO image I have shared with everyone here on SGL) which is why any comments and tips on how to improve will be gladly received. The technical details are: - SW Evostar 80ED DS Pro on a Celestron AVX mount - Canon 500D DSLR unmodded, captured by APT - 20 x 90sec subs @ ISO800 unguided - 10 darks - 30 flats - 30 bias shots - stacked in DSS and processed in GIMP Thanks everyone for taking the time to help me in my journey into these dark arts.

  7. Thanks for the info. Makes a change to not see a big long list of expensive kit needed for this great result. It also beats the long set up and take down time of a scope and EQ mount . Guess what I'm gonna be doing the next time we have a clear sky here? ;-) Sent from my iPhone using Tapatalk
  8. Great image! Could I be cheeky, and ask how many subs you took, how long each one was and at what ISO, as I wouldn't mind having a go at this myself... Also - did you have it mounted on an EQ ? Sorry for all the boring questions, it's just that I'm a bit of a newbie to AP and am keen to learn :-) Sent from my iPhone using Tapatalk
  9. Great choice! I bought one of these back in March - for the money, you simply can't beat it. Looking forward to your obligatory first light report :-) Clear skies... Sent from my iPhone using Tapatalk
  10. Looks like that's the path we must tread then :-) Sent from my iPhone using Tapatalk
  11. I had a go at the ASPA routine for only the second time last night and found it really straight forward. I was trying out my illuminated reticle too which really seemed to help the 2 star and polar alignments beyond what I am used to. I did a bit of homework before I went out so that I knew what star I was going to use in ASPA Rasalhague seemed in a very good position - almost due south and at a decent elevation. After a little bit of alt/az adjustment as per the manual I was all set although I couldn't quite get my head around "unsyncing" previous stars as mentioned in the manual so I just powered down and then quickly did a new 2 star alignment plus 1 calibration star again. There must be an easier way than this though. Can anyone talk me through it??? Sent from my iPhone using Tapatalk
  12. Thanks everyone - looks like all calibration types are done at the same ISO as the lights. Well that's nice and easy. Wish I could say the same for dew prevention. I spent just under an hour of imaging on lights of m27 last night plus all the rest of the calibration frames on top of that just to find out that most of my lights were near useless due to fogging by dew. Does anyone have any experience of using dew heaters? Do they do what you hope they will do? Sent from my iPhone using Tapatalk
  13. Just a quick question everyone - should I be shooting my flat and bias frames at the same ISO setting as my subs and darks, or is there a more general ISO at which to shoot these calibration frames? Adrian Sent from my iPhone using Tapatalk
  14. You've hit the nail right on the head there Droogie!!! The expenses associated with AP seem to grow exponentially in proportion to the number of consecutive cloudy nights we have, as we all fill our slack nights hunting for that next "essential upgrade" then trying to justify it to our nearest and dearest ;-) Glad we are all in this boat together though. Keep us posted as to how things progress ... Sent from my iPhone using Tapatalk
  15. You've made a great choice! I bought one of these mounts back in march as my 1st eq and I can't praise it enough. Your proposed plan of action pretty much mirrors what I did so I think you'll be fine. Like you, I came to the conclusion that an illuminated reticle would make the set up process a lot more accurate for centering the stars in the eye piece so I've just bought a celestron CrossAim from Rothervalley optics for around the £55 mark but typical, I've not had a clear sky since to test it ( I'm really chomping at the bit here!). I'll let you know how it performs as and when. As for ASPA - although it's called "all star" polar alignment , you clearly can't use ALL stars as I found out. From what I remember from the tutorial on YouTube , an ideal star for this should be in the south roughly 45 degree elevation so this will change with each passing month. Best thing I think is to do a little homework before your session with eg stelarium to see what named star will roughly be in this position at the time you're outside. That way you will get the most out of ASPA (the handset gives you the choice of many ASPA stars, not all will be useful or visible depending on surrounding landscape etc). Let us know how you get on. Clear skies. Adrian Sent from my iPhone using Tapatalk
