The Missing Messiers
Posted: Sat Jul 11, 2020 4:02 pm
Working on processing the final dozen Messiers, got them all last night. Will post in groups as processing progresses. First group, in order of acquisition, M62, M28, M69, M70 . All a bunch of globs in the far southern summer sky, usually in the muck of summer haze and a dozen or so degrees above the horizon. Of this group, M62 seems to be a fine cluster, if it was only 40 degrees higher in the sky, I would point the Bigdog at it.
All imaged in my AT80LEAPO doublet at f6, 480mm efl, 10 to 20 one minute subs thru ASI1600MC-cool OSC , gain 200, offset 50, temp -16C, UV/IR filter. Overkill for guiding with 2500mm efl Bigdog, well at least it had something to do last night. All images center 25% crop of full frame.
Clear skies,
Steve
