Hi , I have A problem with my Stellalyra 6" F12 Telescope , you can see a huge Diffraction Around Venus I searched how to fix it but i couldn't Find A solation I Tried to collimate The Telescope but The Diffraction still There
Problem with Classical Cassegrain Telescope
Is the image shown processed in any way, say by unsharp-mask (it looks that way)? Because if it is than it is just the processing at fault, not your telescope.

no this is not A processing Fault Because it is Visible During Imaging (I can see The Diffraction with SharpCap and FireCapture )
I don't think the ring has anything to do with collimation but a lot more with the acquisition process, typically the focusing may not be accurate enough. Try to image the Moon and we should be a much firmer ground there (Venus is notoriously a tricky subject to get right).

Need advice for collimation of Skywatcher 200P
Hi, I've recently got a Skywatcher F4 200P reflector used but have some problems collimating it. I used ocal for collimation inside room, but after I take it out and put on the mount, I find stars are always not satisfying. I tried the next night...
Collimation issues with reflector telescopes may help diagnose diffraction problems.
