Hi again, decided to update! My 8'' Dob arrived few days ago, and I got to test it yesterday! It has been very cloudy and rainy here, so I could only see some bits of the moon for a very short time before the clouds took over, but I am impressed (and my parents too!) 😃
But in case @johninderby is around (or anyone with more experience than me..), I might have few questions. To have enough "outward" focus with the 25 mm eyepiece to get sharp images, I needed to add the drawtube extension. Is that, kind of, normal (I noticed you use it with your 10'' dob)? If it is, then my intuition says that with shorter focal length (like 10 mm) eyepieces I need to focus more inward, is that correct? I did not collimate the dob, as it looked okay for now when following the manual instructions, and for star test, well, they were hiding behind the clouds... I also noticed you had nice handle attached to the tube, which I think would help a lot. Did you just drill screw holes to the tube or how is the handle attached? Will the screw ends affect to the image, I guess they should be painted black at least? The finder was okay, but I found it slightly difficult to use as the image is also upside down. Not sure if it would be easier if I get a finder that shows the sky as it is (to first pick object by naked eye, then from the finder and so on) or if it is just matter of learning, any suggestions/thoughts?
