NGC 4111
NGC 4111 is a lenticular galaxy in the constellation Canes Venatici. It is located at a distance of circa 50 million light years from Earth, which, given its apparent dimensions, means that NGC 4111 is about 55,000 light years across. It was discovered by William Herschel in 1788.
L = 21 * 1200 sec. bin1, R = 13 * 1000 sec. bin2, G = 13 * 1100 sec. bin2, B = 15 * 1200 sec. bin2.

NGC 4414
NGC 4414 is an unbarred spiral galaxy about 62 million light-years away in the constellation Coma Berenices. It is a flocculent spiral galaxy, with short segments of spiral structure but without the dramatic well-defined spiral arms of a grand design spiral.
NGC 4414 is also a very isolated galaxy without signs of past interactions with other galaxies and despite not being a starburst galaxy shows a high density and richness of gas - both atomic and molecular, with the former extending far beyond its optical disk.
L = 62 * 900 sec. bin1, R = 15 * 1000 sec. bin2, G = 15 * 1100 sec. bin2, B = 15 * 1200 sec. bin2.

M 95
Messier 95, also known as M95 or NGC 3351, is a barred spiral galaxy located about 33 million light-years away in the zodiac constellation Leo. It was discovered by Pierre Méchain in 1781, and catalogued by fellow French astronomer Charles Messier four days later.
L = 30 * 1200 sec. bin1, Ha = 10 * 1800 sec. bin1, R = 11 * 1000 sec. bin2, G = 11 * 1100 sec. bin2, B = 11 * 1200 sec. bin2.
