Another test image, this one for testing guiding with long exposure. I know it's not the best Crescent Nebula you had ever saw, but still, 300s exposures is a first for me. I will revisit this target later.

I was also using a GSO coma corrector, and I didn't liked it, so 'm sending it back to change it to a Sky-Watcher one
