Arcturus

[Mandy D]

This is just a star field that I was using last night to focus the telescope prior to imaging the Moon, but I got some nice diffraction spikes on Arcturus, courtesy of my Skywatcher 200P.

Thank you! I think it has proved my 200P quite nicely.

I also use 200P and this is one of my favorite focusing starts Question: I have observed the same thing when I take a photo of a bright star, because it's hard to describe it, I encircled it:

Is this normal? Why is it just on one side? I always blamed collimation, I thought I'm doing this wrong and couldn't collimate properly. Is it actually a problem for imaging anything different than bright stars?

 

Thanks
