I just got a 10” SkyWatcher solid tube dob from gumtree. This was not planned but the deal was too good to pass. I am coming from AP, refractor-only background (and GOTO mounts) so this is all very new to me.
I cleaned everything and washed the primary mirror as per instructions on IIS as it was covered in (dog?) hair. The next step is the collimation. I tried with a film cap but I am not sure what I am doing and I don't think I did a good job. I am looking at getting a tool for this. I read lots of positive about the
Orion Collimating Eyepiece.
Is this still a good choice for collimating both mirrors?
Is there any advantage in also getting a cheap laser collimator at the same time (to save postage)? I assume that the cheap laser collimators may need collimation themselves but that does not look too difficult.
What other "essentials" should I be looking at?
Fan for cooling down the mirror?
Observing chair?
Thank you in advance
