  1. That's good to hear. Hopefully everything will be ok with it so I don't have to return it! Oh yeah, I know the belt setup is not standard for the EAF but I appreciate you flagging it! I'm going to be connecting the EAF directly to the focuser in place of one of the adjustment knobs using the connectors provided.
  2. Thanks for the quick reply. Don't worry about checking the lengths if you have to take things apart. I'm sure I'll be able to figure it out when it turns up. 😄 I am a bit weary about having to permanently modify the bracket just to fit the EAF if I'm honest as once it's done I can't really return it if I'm not happy! I prefer things to fit right out of the box, haha. I wouldn't have minded if I could buy a separate bracket designed for the BDS.
  3. Sorry for bumping this but I've just ordered a ZWO EAF to be fitted on a BDS like in the first picture and I have a couple of questions. Am I right in thinking that the slot on the mounting bracket is too small for M6 screws and will need will need to be widened in some way? Also, can you remember how long the screws were that you used to fit the EAF to the focuser? Thanks!
  4. Wow, prices have really increased since I bought my Evolution 9.25 five years ago. It now costs nearly £1,100 more! Obviously it's not FLO's fault but I was surprised at how much prices have gone up.
  5. Thanks @geeklee and @Clarkey I'm using the native ZWO drive in APT and I had the "Manage gain" option ticked in the CCD settings tab. I think this means that I need to explicitly state the gain in the plan settings which I set at 100 (unity gain as far as I'm aware). I'd left the offset field blank in both the CCD settings and plan settings but I think should have set at around 50 as Clarkey says. I guess there's not much I can do about it now but at least I'll know for next time whenever that is, ha ha.
  6. Very nice. I can see the dark detail the extra data has brought out. It's a lovely image.
  7. Ah, trees. I ran into that problem the other night. I look forward to the result.
  8. Bortle 2! I'm jealous, ha ha. It's still a great capture and I'd love to see what would get with more time.
  9. One thing I completely forgot to mention in my original post but wanted to ask about is offset. I set the gain manually in APT but forgot to put an offset in my plan details. The FITS header shows an offset of 1 in my captures but I've read I should use a value of about 50. From what I can see using an offset that's too low can cause clipping. Will I have lost some detail by not setting the offset properly?
  10. Wow. I'd say that's a great image in general but for 10.5 minutes it's amazing! It puts my efforts to shame
  11. Thank you. Whatever my next target is I know I need to get a lot more data. I'm going to have to make a serious effort in learning to use layers and masks to get the most out of my images particularly when imaging objects like M42 where multiple exposure times might be needed for different areas. Time to start looking for some tutorials!
  12. I bought an ASI533MC last year and I finally managed to use it for DSO imaging on Tuesday night. I've messed around with my DSLR before but I found it fiddly and what data I did get seemed very noisy and hard to process so I never really got far with it. This was also my first real attempt at guiding and I'm not sure if it's uncovered an issue with the mount (large DEC backlash). Sky-Watcher Evostar 80ED DS-Pro with 0.85x reducer/flattener ZWO ASI533MC at -15c IDAS D2 filter HEQ5 Pro 28 x 120s lights (56 mins) - I lost M42 behind trees so I couldn't get anymore data Darks, flats and dark flats used Captured with Astro Photography Tool Stacked and light pollution\gradient removal in Astro Pixel Processor Levels and curves in Photoshop (I don't know how to do much else!) PHD2 guiding Bortle 7 I know it's only a short integration time and I've probably stretched too much so there's still a lot of noise. I need to find out how I can reduce the hot pixels and the halos around bright stars

    DSO Imaging

  14. It's very sporadic for me and sometimes I can go for long periods without setting up my scope. I've been trying to get a proper start in imaging but it's just not possible to do anything in the brighter spring/summer months as I usually have to be finished by midnight. I know I'll never be able to put the time in to capture anything like the stunning pictures posted here but what I do get will be mine. I actually love the early nights and I'm looking forward to September when I reckon I'll start to get some usable time with my new ASI533MC...weather permitting, of course.
