Hi all, I have an APM LZOS 130/780 refractor with a collimatable lens cell.
I've never used it for visual and dont plan to, ever. It's setup with a Nightcrawler focusser and cooled camera, filter wheel, OAG etc virtually permanently attached.
I'm suspicious of the scopes collimation, but I'm so often battling tilt and spacing it's really hard to tell.
Whenever I search on refractor collimation what comes back seems oriented to those doing visual observing and so recommend star test with high power eyepiece using Polaris (which incidentally isn't an option where I live) which would entail setting scope up for visual first and second doing that dance of laying on the ground checking and then up and tweaking screws and back and finding it's the wrong way and back and back all while mosqitos buzz and the brief periods of clear sky dissappear (spent a lot of time doing this with an SCT for planetary)... and presumably a camera is as good as an eye anyway right?
So can I check collimation via the camera view as well as with an eyepiece (what should I be looking for and best approach) and is there a good approach for collimating a refractor indoors when it's raining so I dont waste imaging time?
Really appreciate any advice I can get here.
