M 84, M 86 and more

by on May.25, 2012, under Messier Objects, NGC Objects

This is only a small part of the Virgo cluster of galaxies, which contains about 1500 galaxies in total.
In this image, the following galaxies are easily spotted, from right to left: M84, M86 with NGC 4402 above, NGC 4425, NGC 4438, NGC 4435, NGC 4461, NGC 4458 and NGC 4473 in the far left, upper corner.
Close inspection will reveal even more smaller and fuzzy galaxies.

Type: Spiral Galaxy
Distance from earth: ranging anywhere between 50.000.000 and 60.000.000 ly, and beyond
Constellation: Virgo
Telescope: Robtics 115mm triplet apo @ F/6.9
Camera: Atik 383L+ monochrome
Exposure: single 600s shot, no darks
Filters: Hutech IDAS LPS-P2
Additional accessories: Robtics field flattener, Starlight Xpress USB filter wheel

This is actually the very first image taken with the new (secondhand) Atik 383L+ monochrome camera and the Starlight Xpress filter wheel.
It was just a test, because I wanted to see how deep it could go. I think it’s a great start, considering it’s only a single shot.

A.k.a. Whirlpool Galaxy
A.k.a. NGC 5194
A.k.a. Arp 85
Type: Spiral Galaxy
Distance from earth: Approx. 23.000.000 ly
Constellation: Canus Venatici (Hunting Dogs)
Telescope: Robtics 115mm triplet apo @ F/6.9
Camera: Atik 383L+ monochrome
Exposure: 8x 600s + 1x 600s dark

The smaller, interacting galaxy is known as NGC 5195. Both galaxies are also referred to as M51a and M51b (the last one being the smaller galaxy).
