Dob and collimation
Hi all.
I have 10" collapsible dob.
Tonight (northern Tas) was clear sky but slightly dewy.
When I tried to focus, I could sharpen my eyepiece but kept getting "staring" for the want of a better term. It was like beams of light coming off everything I was looking at. Quite frustrating really. Also, I could see rainbow colours when trying to focus on Mars and Jupiter.
Does this mean collimation is out?
I was using my 2 X Barlow at times. What are ideal eyepieces to use?
Another thing I had was that my eyes couldn't focus too long in the eyepiece when searching for stuff. Maybe too much outside light around me? I am in my back yard. No streetlights but do have lights from next door.
I hope this all makes sense. I can clarify if need be.
