I have a R200SS telescope which is F4.
The secondary alignment is probably close to correct from the factory since the spider vanes are very thick and sturdy.
The primary is a little bit out of alignment because I bonked the end of the telescope and stars at one side of the image are a little crooked.
I will be using a coma corrector with it.
I use this scope for imaging only, so I expect that after whatever collimation I do, hanging the camera and filter wheel off the focuser is going to bend it a little bit.
Ideally I would like to finish up with a "star test", but the combined tube currents and seeing are just too bad to get the nice Airy disks. I would try using a Tri-Bahtinov mask or take images and use CCD inspector to look for coma / elongation.
To use the collimation kit requires I take off the imaging train and screw in a 42mm to 1.25" eyepiece adapter. It is about 1.5" tall, and I can't jam anything in further than that without hitting the coma corrector.
Primary is also marked with a donut. I don't wanna have to spot the secondary.
The two kits I am looks at are:
Farpoint 1.25" kit = Cheshire + laser
Astro Systems kit = sight tube + autocollimator
Which combo would work better given my situation? Or maybe just one tool, or none at all?
