Hi there,
I've had my Dob for a few months now, and been out in the garden as much as possible enjoying the night skies as much as the clouds let me.
Really loving the views you can get through 10" of aperture compared to what my old Tasco use to give me (had it from being a kid).
The only issue I'm having is it struggles to hold collimation, I have to recollimate every time I set up. I take the scope off the mount every time I move it outside, and back inside when I'm done, placing it very steadily every time I put it down. After collimating it I make sure I see the perfect doughnut in an unfocused star, so I hope I am collimating it correctly.
From what I read these Dobs seems to hold collimation pretty good, and shouldn't need it every use. Just wondering if I could be doing anything wrong - and hoping its nothing wrong with the scope itself!
Quick note, I dont think its this but it concerns me everytime - I tighten the primary mirror knobs finger tight every time, not too tight as I dont want to 'pinch' the mirror - Should I maybe try tightening harder? Or is it easy to pinch the mirror?
Thanks for your help in advance!
