My first attempt at imaging the Orion Nebula using this equipment. Also the first clear morning in a while here in Yuma (post monsoon, I hope!) This area is Bortle 4 but I live near some businesses and street lights that make using a light pollution filter necessary. It also appears as though a field flattener would help.
