9/5/2013 Great Lakes star Gaze 11 Gladwin MI new
      #6082575 - 09/15/13 06:29 PM

Thursday September 5, 2013 10PM to 3AM Friday K. Anderson GLSG11 Gladwin,MI w/ 17.5" f4.1 dob with 20mm 100AFOV & 40mm 70AFOV both w/ Paracorr II. The sky was perfectly clear, no clouds, cold with dew (issue with filters, telrad & eyepieces). No moon was present on this new moon night. Arrived and set up my tent in the twilight/dark next to Jon Blum, Dale Partin, & Bob Berta. Set up dob in the dark. Tonight's goal was observing all the Sagitarius objects listed in the Telrad "Best 300" pages 45 & 44. Also used p 69 of S&T pocket sky atlas. Naked eye able to see Milkyway, great rift, M31, C14 double cluster, Coathanger, M7, M8 Lagoon, M24, M45, Hyades, Perseus A cluster, but not M33. Typed from my hand written notes the day after observing.

20mm 100 AFOV Explore Scientific(0.95 deg TFOV, 105x, 4.2mm exit pupil) with 17.5" f4.1 Discovery Dob w/ Paracorr II most used tonight:
*M7 larger than TFOV (panning two TFOVs) and very bright
*M6
*Looked for M4 but it had already set behind the trees
*Could not find C68 near horizon
*M54
*M70
*M69
*SD79(NGC6528) and SD78(SG99/NGC6522) rememorable both very clear just above next to tip of Sagitarius teapot spout. First time I remember them looking so good and bright due to Gladwin's dark skies.
*HT88(R103/NGC6250)
*M8/NGC6530 (OIII best for bright nebulaee clear/dark lane, and dimmer nebulae filling view extending beyond the cluster, UB, Skyglow best for both nebulae/cluster, Unfiltered very hard to see Trifid).
*M20/M21 same view first time I have seen both in same view of this eyepiece just inside edge at 11 and 5 o'clock, M20 Trifid is faint and higher object (OIII, UB, Skyglow best for both Trifid nebulae/cluster, Unfiltered nebulae faint).
*M24/NGC6603 Very large requiring panning two TFOVs & bright.
*M28 small and bright
*M22 large and bright
*M13/NGC6207 in same view! M13 bright at 1 o'clock near edge and small dim/faint NGC6207 galaxy at 5 o'clock halway to center.
*Could not see/find HT99(R102/NGC6818) too low to ground
*M23
*M24/NGC6603 Very large requiring panning two TFOVs & bright.
*M25
*M18
*M17 very bright swan (OIII best, UB next best, Skyglow, Unfiltered still visible).
*M16 hard to find/confirm since looking for nebulae, but cluster was actually easy to find looking like an angle with arc of stars inside, and I drew a quick picture of it from memory. did not respond to dewed up OIII, UB, nor skyglow filters. Unfiltered looked best. since I was expecting a nebulae I initially thought it may have been NGC6604.
*M11 looked great! Very Bright Right angle cluster with one very bright star in the center.
*M26
*Could not find HT15(R94/NGC6712)
*C20(NGC7000) Nort American Latin america bright 3 star region (OIII best, UB, Skyglow, unfiltered)
*C33 (NGC6992/5) Eastern Viel had to pan to see whole thing (OIII best, UB, Skyglow, unfiltered)
*C34 (NGC6960) Western Viel had to pan to see whole thing (OIII best, UB, Skyglow, unfiltered)

40mm 70 AFOV Koenig University Optics (1.33 deg TFOV, 53x, 8.5mm exit pupil) with 17.5" f4.1 Discovery Dob w/ Paracorr:
*M24/NGC6603 Very large & bright.
*C33 (NGC6992/5) Eastern Viel curved and mottled had to pan to see whole thing (OIII best, UB next best, Skyglow, unfiltered still visible)
*C34 (NGC6960) Western Viel straight witches broom with star had to pan to see whole thing (OIII best, UB next best, Skyglow, unfiltered still visible)
*C20(NGC7000) Nort American Latin america bright 3 star region (OIII best, UB, Skyglow, unfiltered). Had to pan to see dim gulf of mexico.
*C63(NGC7293) Helix Nebulae large dim faint object. Last object found in my scope.

10mm 100 AFOV Ethos(0.48 deg TFOV, 210x, 2.1mm exit pupil) with 17.5" f4.1 Discovery Dob w/ Paracorr II:
*M13 very bright did not look for NGC6207 galaxy?

3.7mm 100 AFOV Ethos (0.19 deg TFOV, 568x, 0.8mm exit pupil) with 17.5" f4.1 Discovery Dob w/ Paracorr II:
*M13 filled view, stars not pinpoints, near zenith. Did not look for NGC6207 galaxy.
*Several Waxing Gibbous Moon Craters near terminator (Skyglow)

Jim Mosheck's 15" Dob:
*C33 (NGC6992/5) Eastern Viel curved and mottled and very nice (unfiltered?)
*C34 (NGC6960) Western Viel straight witches broom with star very nice and mottled (unfiltered?)

Steve Harvath's 6" Takakasky Reflector:
*C20(NGC7000) Nort American Latin america bright 3 star region (OIII).
*C33 (NGC6992/5) Eastern Viel curved (OIII)
*C34 (NGC6960) Western Viel straight witches broom with star (OIII)
*C63(NGC7293) Helix Nebulae large dim faint object.
*C62(NGC253) Sculptor galaxy nice and mottled
