Another great video. Thank you. Hopefully, either NINA or Hocus Focus will adopt FocusMax's approach whereby it will select a start based on your brightness-selected criteria, plate solve and slew, conduct the autofocus run, then slew back to the target and resume imaging. Relying on finding a suitable start within the imaging FOV doesn't seem like the best approach, and certainly not if it means have to do the back and forth manually. The current way always seemed clunky and I spent a lot of time looking for a way to make it do what F'Max does.
I've never even heard of FocusMax. I'll have to look into it, though I don't shoot enough NB to make it a priority right now. You're absolutely right, though. The NINA way is a little clunky for that type of focusing. NINA offers a lot, but it needs to streamline both its image processing and focus routines. I am sure it'll get there in time, though.
Great video. Very helpful. I have very different results with narrowband (3nm) focusing from my bortle 8.5. 8 seconds is totally fine for me…I get consistently good results, even without parfocal filters (I have 2 Antlia 3nm and one Chroma 3nm). I’m generally shooting pretty wide, 180mm-300mm, for what that’s worth.
I think your focal length may have something to do with your speed in focusing the NB filters. What is the F ratio of your telescope/s? With the SCT at F6.9 I am happy if I can get that Sii to focus reliably in 60 seconds. But probably if I pointed it at some brighter stars I might have more lucky. The one I was using when I shot this was mag 2. Wait...no, I wish I had written it down. It could have been a little dimmer. Main thing is use as bright a star as possible anyway.
I came here to say the same thing. I'm wondering what focal ratio/length the author of this video is shooting at. I shoot at f5.6 and have never needed to go longer than 8-10seconds at unity gain on my 2600mm with Chroma 3nm filters.
I have bought the Player one Uranus camera for DSO. In the past I used a canon DSLR. What would you suggest for bin gain and offset I have a tri color filter as a starting point.
Congratulations! I am sure you'll like that camera. In general, shoot at unity gain (the place where noise is minimized). That's around 210. Maybe go to 220 to be sure you have crossed into unity.

You got me curious so I just looked up FocusMax. Looks nice but at $200 for a license I think I'll stick with NINA.
I am still using SGP but these function are also available there. Thanks for the tips!

@@NevadaDesertSkies I was a using a Celestron C8 at 1240 FL and F 6.9 with the reducer. It would have helped to focus on brighter stars, for sure.
