Description

I did a test with the Celestron C9 and a APM coma corrector 2.7 x,combined with ASI 1600 mm
So the focal lenght in total was 6345 mm.
It worked well,because whe have some very steady nights here,very dry also because of very high temperatures in Europe.

My target was M57,its so tiny  but with this length is showed lot of details,even see stars in the core and ring.

Greetings all !!
John
