Description

Last week I was performing a few tests with my Celestron C 9.25 and a Astro-Phisics focal reducer just to check if they fit together.

Unfortunately there was a lot of turbulence and passing veils so the FWHM is huge (about 4.5 pixel)

Despite this problems this test are not so bad do I decided to publish this picture.

Is a Ha RGB composition.

All the pictures was without any guide
