Rosette Nebula 2018-11-10

Rosette Nebula

During the same night I imaged the Rosette nebula, acquiring 10 x 5 min, ISO 3200, with the Canon 1100D mod, Canon EF 200mm f/2.8 L II USM at f/6.3, HEQ5, with the IDAS LPS D2 filter clipped in. Compared to my previous attempts, I find this result a more natural, more smooth outcome.

A Gemini region – 2018-11-10

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.

Seagull Nebula

The same night I imaged the IC 2177, SH2-296 [nebula in Mon] Seagull Nebula, Sirály-köd, Sharpless 296, SH2-296 ø120′ [wiki] [simbad] 200mm, gathering 10x195sec at f/4 ISO 3200 with the Canon 1100D mod, Canon EF 200mm f/2.8 L II USM at f/x, HEQ5, using the IDAS LPS D2 clip in filter. For this one I also used my starheal.

California nebula – 2018-11-10

California nebula

I managed to dial down the chromatic problems (astigmatism?) of my Canon EF 200mm f/2.8 L II USM, by adjusting the lens’s mount, but it’s still bordering garbage for astrophotography’s needs.

I imaged NGC 1499, SH2-220 [nebula in Per] California nebula ø160′ [wiki] [simbad] 200mm, 400mm  on 2018-11-10, with the usual wide field rig, Canon 1100D mod, Canon EF 200mm f/2.8 L II USM at f/4.5, HEQ5, acquiring 21×90 sec of light at ISO 3200. An extra is the IDAS LPS D2 clip in filter.

The Moon – 2018-09-20

This is the first light of the ASI 120 MM camera, the most recent addition to my instruments. The Moon below is a mosaic made with the N 150/750 and through a Barlow lens.

Looking for Neptune – 2018-09-12

Neptune and Triton, I think

Neptune is not that hard to find, in theory. Add light blinding pollution, a not so accurate polar alignment and some passing clouds, and it becomes a PITA.

The other thing is, that IF the object I photographed is indeed Neptune AND Triton, the moon is off  compared to Stellarium. I intentionally photographed a reference star too, so I could put it on a map. However, the map itself is the DSS and some stars may have just moved away.

The gear: N 150/750, 2x Barlow and empty extension tubes, the ASI 224 MC camera, on the HEQ5 mount, in the city. 2018-09-11 22:26Z, ie 2018-09-12 1:26 local time.

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.).
