Well originally I posted this on the "Beginning and Intermediate Imaging" forum, but seems like it isn't the ideal place because nobody answered me.
The day of the lunar eclipse I took some data of M42 with my new Explore Scientific ED127 refractor simply as an experiment to see how it worked, the brightest stars have some kind of flare and chromatic aberration, that's normal or my scope have bad optics? Or it's because I wasn't in good focus? I'm pretty fresh in this, it's my first refractor and was my first time trying to do deep space astrophotography, so I really don't know what to expect, the mount wasn't well polar aligned, the seeing that night was "normal" around here. This is a single 13s ISO 3200 capture with my Canon 70D and a crop of the same.
