Re: 10 and 11 July Coronado PST Double Stack focusproblems

I think your tuning is way off.

Don't use the double stack until you have sorted the tuning in single stack.

If the focus is still off west when the tuning is right, I would say your penta prism in the PST is off.

Follow this iterative approach to find the root of the problem.

Re: Ca-k close ups from today

These are excellent Dennis! Your findings exactly mirror mine - the filters are very sensitive to tuning, and extra glass introduces more SA at CaK. The latter, in my case, along with seeing that is rarely better than 1" is one of the main reasons I've stuck with stopping down refractors to get...

Re: Solar limb AR 3729 5.7.2024.

Nice shot! I agree with Dennis. You might also want to try and sharpen at a smaller radius / kernel size, you will find you are blurring out some of the finer details sharpening at too large a radius, you can see this when the image is viewed full size.
