  1. Yeah phd 2. Thanks, I’ve been imaging for 3 years and never fully understood which number to take notice of.
  2. Ah thanks, yes it has the correct focal length and guide camera pixel size. Another daft question but which numbers do you go by, the number in brackets or the first number?
  3. I moved to Nina from apt before the latter had the autofocus capability. I won’t go back now it is excellent. I am still using version 1.10 as I found the nightly builds a bug fest.
  4. Hi folks, I’m sure this is a simple question for many people. How do I convert total rms error from my phd graph to meaningful error in arc seconds? Thus allowing me to compare it to the imaging cam imaging scale. Thank you
  5. I don’t think so, I started with a 72ED with the same camera and have progressed to a GT71. It was still the same. I thought it might be over saturation and or the high pixel count that is causing it. I found it annoying as it is very difficult to determine correct focus
  6. If I recall, the spikes looked straight when checked with my nb filters but with rgb filters the spikes would look wonky.
  7. I had the exact same issue with my 183mm although it is a Altair camera. I never got to the bottom of it and now use an electronic focuser.
  8. He has had my mount for 15 weeks now. Emails rarely answered, managed to speak with him 3 weeks ago and was told my mount was ready and just needed testing. I sent an email a couple of days ago asking for an update and no reply. Why advertise 4/5 turn around when he must know this won’t happen. I’ll be ringing tomorrow and if I don’t get answer I’ll be requesting a refund. I hope his work is better than the customer service.
  9. your Sii data looks very good. What is the outcome with the scratches?
  10. Look forward to the results. How long are your exposures and setup?
  11. Thanks I am about to purchase a new Oiii filter, my current cheap filter gives huge halos. I can’t decide between the 3.5 or the 6.
  12. Hi folks, I see there is a lot of discussion on here regarding different manufactures of filter but my question is are the new 3.5 nm filters worth the extra £££££ over the cheaper 6nm filters? I am looking to upgrade my cheap Oiii filter which is giving very bad halos. Thanks
