Another Leo triplet member, NGC 3628

 PRoblems again with DSS not detecting enough stars; didn't have many lights anyway and lost most of the R, G and B when stacking. Hence, very noisy image. Maybe I should use the lens corrector and make a smaller FOV?

Horsehead Nebula and one of a triplet

 Over a couple of nights I took subs of Barnard 33 The Horsehead Nebula in Orion and Messier 66, one of the members of the Leo Triplet of galaxies. Both images have around 100 mins on La,d 30 each of R, G and B.

Barnard 33 The Horsehead Nebula in Orion

Wikipedia: The Horsehead Nebula (also known as Barnard 33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. 

The dark cloud of dust and gas is a region in the Orion Molecular Cloud Complex where star formation is taking place. It is located in the constellation of Orion, which is prominent in the winter evening sky in the Northern Hemisphere and the summer evening sky in the Southern Hemisphere.

Colour images reveal a deep-red colour that originates from ionised hydrogen gas (Hα) predominantly behind the nebula, and caused by the nearby bright star Sigma Orionis. Magnetic fields channel the gases, leaving the nebula into streams, shown as foreground streaks against the background glow. A glowing strip of hydrogen gas marks the edge of the enormous cloud, and the densities of nearby stars are noticeably different on either side.

Heavy concentrations of dust in the Horsehead Nebula region and neighbouring Orion Nebula are localized into interstellar clouds, resulting in alternating sections of nearly complete opacity and transparency. The darkness of the Horsehead is caused mostly by thick dust blocking the light of stars behind it. The lower part of the Horsehead's neck casts a shadow to the left.The visible dark nebula emerging from the gaseous complex is an active site of the formation of "low-mass" stars. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming.

M66 in Leo

Wikipedia: Messier 66 or M66, also known as NGC 3627, is an intermediate spiral galaxy in the southern, equatorial half of Leo. It was discovered by French astronomer Charles Messieron March 1, 1780, who described it as "very long and very faint". This galaxy is a member of a small group of galaxies that includes M65 and NGC 3628, known as the Leo Triplet, or the M66 Group. 

M66 has a morphological classification of SABb, indicating a spiral shape with a weak bar feature and loosely wound arms. The isophotal axis ratio is 0.32, indicating that it is being viewed at an angle. M66 is receding from us with a heliocentric radial velocity of 696.3±12.7 km/s. It lies 31 million light-years away and is about 95 thousand light-years across with striking dust lanes and bright star clusters along sweeping spiral arms. As of 2018, five supernovae have been observed in M66: SN 2016cok, 2009hd, 1997bs, 1989B, and 1973R. The one detected in 2016, SN 2016cok was discovered by the All-Sky Survey Automated Survey for Supernovae, and it has been categorized as a Type IIp supernova.

M82 Cigar Galaxy in Ursa Major

 A beautifully clear, moonless night. Last session I had imaged Bode's Nebula, so I though I would do its companion, M82 tonight. Around 32 mins in RG and B and 102 mins in L, all at 1x1, gain 139.

Wikipedia:

Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major. A member of the M81 Group, it is about five times more luminous than the Milky Way and has a centre one hundred times more luminous. The starburst activity is thought to have been triggered by interaction with neighbouring galaxy M81. As the closest starburst galaxy to Earth, M82 is the prototypical example of this galaxy type. SN 2014J, a type Ia supernova, was discovered in the galaxy on 21 January 2014. In 2014, in studying M82, scientists discovered the brightest pulsar yet known, designated M82 X-2.

Bode's Galaxy in Ursa Major

 The previous night I had collected five hours of data on M106 to find that DSS couldn't find enough stars in the subs!!  I think it must be the contrast reducing effect of a full moon. I need to revisit that one to be sure.

Anyway, in order ot check it wasn't a problem with DSS, I took some more subs of M81 and then combined them with ones I took in April last year. So, around 5 hours of L and 40 mins each of R, G and B.

I must admit, I am quite pleased!
