Here's my first jupiter of the year:

Jupiter and moons 2018-06-08-0512 UT

seeing was unusually good:

Jupiter 2018-06-08-0611_1 R-G-B

spent all last year tweaking equipment trying to get a good planetary image and got mush.  this year, first time out with older equipment i got lucky with good seeing, blowing away anything i did with my fine tuned rig last year :(

a few comparisons for imagers:
RGB camera up sampled 2x vs barlow:

RGB camera upsized x2

RGB camera 2x barlow

close, but very slight edge to the barlow

RGB camera barlowed 3x2 minute runs combined:

mono camera 1 minute x 2 each channel:

corrector fogged out before i could get a barlowed mono image :(

not shown: IR filter added little
adding small boxes closer to the edge in autostakkert, gave better peripheral detail
