Stargazerkelly1989 Posted September 6, 2020 Share Posted September 6, 2020 Hey there. I’m in need of some help, I took out my 12” Dobson last night to check out Saturn and Jupiter. I found Saturn and Jupiter very hazy. I don’t know if my telescope needs collimating? Any advice or tips? thanks Link to comment Share on other sites More sharing options...
John Posted September 6, 2020 Share Posted September 6, 2020 The seeing conditions were rather poor last night and these planets are low in the sky. I don't get great views with my 12 inch dob either at the moment (normally it's as sharp as a tack) so I use my refractors to view these planets currently which seem to do better. You can check your collimation by doing a star test on Polaris: https://popastro.com/documents/PA_jan-mar2009_p12-13_telescopetopics_startesting.pdf More likely than not though it's the seeing conditions and position of the planets that is the cause. Try using lower magnifications ? Link to comment Share on other sites More sharing options...
Stargazerkelly1989 Posted September 6, 2020 Author Share Posted September 6, 2020 Ah perfect. Yeh I’m pretty sure I have better views when planets are higher and winter skies seem to be better too. also. How do you clean your eyepieces? My brother put a finger smudge on one 😂😂 Link to comment Share on other sites More sharing options...
