So I made this post after the last one made me question my choices and the title was no longer descriptive of the problem.
Firstly, I only have two reversed Kellner eyepieces so far, the ones that came with the telescope (6", F=1200mm), giving me the magnifications of 48x (for the 25mm) and 120x (for the 10mm one).
I mostly use the telescope for observing DSOs, and while I thought I wanted a zoom, I understand that they are not that great for DSOs due to the FOV. So now I am completely clueless... I was suggested on the other topic that I should buy a fixed focal length eyepiece (around 15mm).
I know how to calculate magnifications, AFOV and TFOV, but I am happy with whatever clarification you might want to add for a newbie like me. What I don't know, is what is the best eyepiece for what I want (observing DSOs) in my budget.
- Celestron zoom eyepiece 8-24mm
- Meade zoom 8-24mm
- APM Ultra flat field 15mm (65°)
- and if after I chose an eyepiece, I have money left, a Barlow maybe?
So I am happy with whatever review or other suggestions you might have!!!
Other considerations: I live in Romania (that's the reason why I have to choose between these zooms - they are the only ones available here under my budget), but I will gladly search here for any eyepieces you suggest that are available elsewhere. Also, no local astronomy club for me to ask there for advice (the closest is 7th away by train)
Thanks you so much in advance!!
