Gemini region

During the same night, I imaged the Gemini region containing:

LBN 844, SH2-248 [SNR in Gem] Jellyfish Nebula [bright] from shc, Medúza-köd  6m ø50′ [simbad] 135mm, 200mm, 400mm, 600mm, 750mm

NGC 2174, SH2-252 [nebula in Ori] Monkey Head Nebula, Majomfej-köd 6.8m ø20′ [wiki] [simbad] 600mm, 750mm

M 35, NGC 2168, Mel 41, Col 82 [open cluster in Gem] M. 35. Large open cluster, well defined and condensed towards centre. 5.1m ø28′ [wiki] [simbad] 750mm

Also on the image:

NGC 2158, Mel 40, Col 81 [open cluster in Gem] A very small Class II or globular cluster. Somewhat similar to NGC 2266. 8.6m ø5′ [wiki] [simbad] 750mm

IC 2156 [open cluster in Gem] [wiki] [simbad] [photo-planner]

IC 2157 [open cluster in Gem] 8.4m ø7′ [wiki] [simbad] [photo-planner]

LBN 843, SH2-247 [H II nebula in Tau] Sharpless 247, SH2-247 [midbright] from shc 8m ø9′ [simbad] [photo-planner]

LBN 845 [nebula in Gem] LBN brightness=4 ø20′ [simbad] [photo-planner]

I put together 5 framings to extend the corners, the main frame contains 16x90s ISO 3200, F/5, using the usual rig Canon 1100D mod, Canon EF 200mm f/2.8 L II USM at f/x, HEQ5 and the IDAS LPS D2 filter.

I think, the best observation night I’ve ever had in Europe, was the night of 2017-10-20, at the Curmături Cabin, in Alba County. There was some airglow, but not a cloud, steady seeing, 21.4m-21.8m sky (the lamp posts were turned off for us, and the few neighbors were kind enough to limit their outward shine), no wind, electricity from the power grid, negligible to no humidity (no dew heaters needed). Although only one night was usable for astrophotography.

I used my usual gear, the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, autoguider.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
