  1. Thanks for sharing that. I'm always interested to see processing techniques in PS as I am certain that my processing leaves a lot to be desired still! I'll have to give this one a try sometime.
  2. This is a bad post for my wallet... I've been considering the 1600MM for a few months and tried this target with my Canon 550D recently (very unsuccessful without any modding, and big camera connectivity issues). Great pics, I really have a thing for SHO pallette....
  3. Thanks, that means a lot. I am often guilty of over-processing a lot of my astrophotography data (especially of deep sky) and I'm trying to bring it back a notch, do without a little detail but keep it looking "real". I'm just so pleased with how this turned out given the awful seeing / low altitude I've had with Jupiter for the last year or 2 of trying!
  4. Thank you! Yes, the seeing just seemed... brilliant all the time I was out there and I couldn't believe how stable it was across the ~1 hr of the time lapse. You're right about the single still detail being less than the animated frames - that's probably just my own processing though. I think I took a lot more care with the animation (in fact, it was my 3rd go that I actually uploaded). I just love the movement though so I couldn't focus on the stills Edit: Forgot to add, yes, it's the 200P reflector in my sig that came off the dobsonian. It's a nightmare to locate objects with it a
  5. Hi everyone. Thanks for looking. I know we're inundated with Mars pictures at the moment but I've not seen buckets of time-lapse and this marks a significant personal best for me so I really wanted to share it. I've not had seeing this good for a long time, especially with a planet this high above the horizon (I'm looking at you Jupiter & Saturn.....). Only 12 frames spread across ~1 hour, but nice to see some movement. One single still as a bonus too Edit to add acquisition & processing: Skywatcher Skyliner 200P reflector (off my dobsoni
  6. Thank you for sharing this fantastic image and annotation. It has helped me identify the correct way up for my images and made me realise that the animated GIF I shared had the frames reversed! No wonder I couldn't work out why Mars seemed to be rotating the wrong way...
  7. Hi vlaiv, thanks for the detailed reply. It is comforting to know that a total RMS of ~0.8" is considered OK/good. Your other points make sense and are helpful too. As you say - get it as good as you can! I am still tempted by the belt mod as I have heard good things about them and, living in a pretty populated area, it would be nice to have a quieter scope. I felt like I was keeping the neighbours up last night slewing....
  8. Thanks, Roland! That's all really useful information. I'll keep an eye on my guiding stats. Last night they ended up averaging over 1" for most of the session but the seeing was poor and the temperature was so high my Canon sensor was at ~40 C the whole time, it was noise galore! As for the NB imaging, I feel like I'm getting closer and closer to giving it a try!
  9. Hello 130PDSers! Having just learned about plate solving (and how to do it properly in APT, which I use for capture) I have revitalised my interest in imaging. I was having real trouble locating targets and centring them but since getting plate solving working I feel WAY more ready to move up in the world. I've been having some problems with my Canon 550D disconnecting from my laptop during imaging and it's really starting to bug me. I've tried troubleshooting in lots of different ways and this has included a complete update of the laptop software, drivers, etc and re-install of all
  10. Thanks, Wim! That makes sense. I was starting to be a bit worried as (at various positions) my guiding total RMS was hovering around 0.8-1.2" but I know for a fact the seeing is pretty poor tonight so I imagine that's affecting my resolution far more. I can at least be glad that the seeing is (mostly) out of my control!
  11. Hi everyone. Thanks for coming to read my question. I have been running PHD2 to guide with an ASI120MC-S on a Startravel 80. My imaging train is a Skywatcher 130PDS newt with 0.9x coma corrector and a Canon EOS 550D. While looking at my PHD2 statistics tonight, I started to wonder "Are these good? Are these good enough? What is good enough?" and it got me thinking. I started googling "what are acceptable PHD2 guiding statistics" and getting nowhere when I realised that I could probably work out what "good enough" looks like, however I wanted to check that I was thinking about it the
  12. I just want to say that this thread is one of the most useful things I've ever come across in my time doing astrophotography. Thank you so much! I set this up today and tonight I had the easiest time finding targets I've ever had BY A MILE. I used to think that my expensive mount was "bad" or "broken" or something because it would take me so long to find what I was looking for, but this has made me realise that actually it was getting pretty close every time and I was just struggling to get that last movement spot on. Now though - wow! Thanks again
  13. That makes sense. Although if the OSC CCD option is going to be notably more expensive than ~£1800 for the ZWO 1600MM pro then I'm probably going to stick with mono for now as that's already really stretching what I'm happy to spend
  14. I think you're right RE: OSC - although as I mentioned above, I love the idea of narrowband as well and I imagine that's not as simple with a OSC camera?
  15. Thanks again everyone for the really positive and helpful comments. I think... as I said my wallet does not thank you, haha. I'm getting more and more tempted to go for it, especially as I watch some processing videos. It seems that a lot of my previous experience with OSC DSLR is directly applicable and it just needs some other extra steps. Thanks, especially for the kind words on the DSLR images! The setup I'm looking at grabbing would be something like this: ZWO ASI 1600MM-Pro USB 3.0 Mono, EFW7 Filter Wheel, 31mm LRGB & Ha/SII/OIII Filters
