Good Morning Everybody,
I recently bought a GSO 12" Dob and have some start issues that I hope you may have an answer for:
- 9x50 finder scope brings only blurry images - can this be focused?
- no focus achievable when using 1.25" 2xBarlow and EP`s shorter than 15mm - but 5xPowermate and 25mm works great
- imagages (visual) appear yellowish
- 2" GSO 30mm EP very blurry closer to edges
Thanks in advance!
Cheers
