I initially thought 180s would be about right (just guesstimate) but NINA told me I was blowing out a lot of pixels so I put it down to 120s. I started getting some RGB last night before the clouds and threatened rain and those were fine with 180s. Link to comment Share on other sites More sharing options...

Well, quite simply because I got it collimated (by Orion Optics) plus a fellow owner is talking to a Chinese fabricator about a focuser that should be a direct swap (like the feather touch but less than half the price) that should resolve the nasty focuser issues like the unnecessary (for AP anyway) extension tube and the inadequate compression fitment that you can't remove...

Brady Posted February 26, 2023 Share Posted February 26, 2023 Are you just using the statistics tab to check the pixels in NINA? Bob Dobber 1 Link to comment Share on other sites More sharing options...

It was also noticeably "hot" in the core too. Using the Nina stats is more technical than I normally am. I usually just rely on a bit of gut feel and experience (though I've not got heaps of the latter). Do you have an suggestions? Brady 1 Link to comment Share on other sites More sharing options...

Not really Rob, i use the same routine, although im not sure if your aware but the nina exposure calculator has now been made into a plug-in so not available in the latest software unless downloaded and installed yourself, im set up and ready for a clear to test...could be a while 😐 Bob Dobber 1 Link to comment Share on other sites More sharing options...

I generally just rely on a bit of commonsense, a bit of experience and some trial and error, but if there's something that is a bit more scientfic maybe I should take a look!
