NGC 4536, 4527 and others – 2018-04-08

2018.04.15. admin

NGC 4527, NGC 4536

The known location, the known setup, after six month of unfavorable weather, with clear hours at impossible times for a working class hero – same field trip as before. I acquired 11×5 min of light at ISO 1600.

The main objects on the image, sorted by brightness:

NGC 4536 [galaxy in Vir] 10.4^m ø7.6′ [wiki] [simbad] 750mm, 1200mm
NGC 4527 [galaxy in Vir] 10.8^m ø6.2′ [wiki] [simbad] [photo-planner]
NGC 4533 [galaxy in Vir] 13.9^m ø2.1′ [wiki] [simbad] [photo-planner]
IC 3474 [galaxy in Vir] 14.91^m ø2.24′ [wiki] [simbad] [photo-planner]

The Leo Triplet, M65, M66 and NGC 3628

The known location, the known setup, after six month of unfavorable weather, with clear hours at impossible times for a working class hero. I acquired 16×5 min of light at ISO 1600.

The main objects on the image are, from left to right:

M 66, NGC 3627, Arp 16 [galaxy in Leo] Leo Triplet 2 9^m ø9.1′ [wiki] [simbad] 750mm

The Moon – 2018-01-31

2018.02.04. admin

hold moon

There is nothing special about this date, no eclipse was visible from most of Romania, I simply imaged the Moon. I used the MC 102/1300 plus the Canon 1100D mod for the disk (13 frames) and the Scopium webcam for the details. Enjoy.

When to, what to – photograph

You may already know my astronomy catalog search engine, the DSO. It includes all the catalogs we amateurs use: the Messier, Caldwell, NGC, IC, Arp, SH2, Collinder, Melotte, Abell planetaries, it even grabs the list of exoplanets from a wiki page to always be up to date. But this is not all. It includes some ugly formulae to know about the position of the Sun and the Moon, and do some math based on the geolocation of the user. The DSO however is more like a text mode tool, or an API. It is good to just look up what Messier 51 or NGC 7000 is. Anything more complex requires some heavy wizardry even I don’t master and need to look up in the help I fortunately did write.

NGC 281 Pacman Nebula

During the summer, I imaged the Pacman Nebula, NGC 281 [open cluster+nebula in Cas] 7^m ø25′ [wiki] [simbad] 750mm using the usual setup, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, guided by the resurrected gear, and acquired 25×5 min at ISO 1600.

The Large Magellanic Cloud – LMC

Large Magellanic Cloud

the LMC

The LMC is the largest of the satellite galaxies of the Milky Way. Its surface brightness is higher than that of our galaxy’s. The LMC hosts the most active starburst region known in the Local Group of galaxies, the Tarantula Nebula. I acquired 47×3 min, ISO 800 with a 50 mm f/1.8@f/4.5 on the Canon 1100D mod. During my visit to Namibia, the Magellanic Clouds’ position was the least favorable, thus the pictures aren’t the best. The orange hue on the raw image is due to the strong airglow we’ve encountered, there was no light pollution.
