Re: Test Quark chromosphere
One correction tho. You say you need an expensive ERF above 80mm, which I assume you mean front mounted. This is not correct.
I only use a 2inch Baader UV/IR rejection filter in front of my diagonal with my 120mm SW Esprit APO refractor.
It's when you go beyond 120mm, that you need to start using a front mounted ERF.

Re: Test Quark chromosphere
Hello, thank you for your comments.
I do not master the English language is an automatic translation ...
I know that up to 80 mm this is not a difficulty not to use a
ERF filter. 120mm but I have a doubt. If you use the Quark to 120mm with just an IR cut is that it works!
I will report on my page, but with the usual caveats ...
Best Regards,
Jef

Yes. From 80mm till 120mm you can use a UV/IR rejection filter in front of the diagonal.
For larger aperture refractor you will need a front mounted ERF filter.
It's stated also in the manual.
