Hello Friends!
It's been a while, Unfortunatly souther Arizona has had a cloudy few months with little rain. Making it an extreamly unproductive summer. However, the skies are starting to clear up and I excited to start sharing some new stuff. Here is my first post of the Crescsnt, although I've imaged this many times most of it is still in the working process. Thanks to the Optolong L-eNhance I was able to capture a very nice image of the nebula that showed plenty of detail with very little processing needed!
