Distance from earth: Approx. 36 +/- 5 million ly
Constellation: Leo
Telescope: Sky-Watcher Explorer-200PDS Newton
Camera: Canon EOS 550D
Exposure: 25x 25s @ ISO1600, no darks or flats
Filters: None

This is the second picture taken with this new setup (although the Canon DSLR isn’t new, it’s my old buddy).
I’m amazed at what can be shown with such short exposures!
Still on my wishlist: coma corrector and IDAS-LPS P2 filter (I wish I never sold this one!).

Note: There is a supernova, it goes by the name of sn2013am, visible in M65 (the upper right galaxy).

A.k.a.: Double Cluster
Type: Open Cluster
Distance from earth: Approx. 7.500 ly
Constellation: Perseus
Telescope: Sky-Watcher Explorer-200PDS Newton
Camera: Canon EOS 550D
Exposure: 50x 60s @ ISO800, no darks or flats
Filters: None
Additional accessories: None

This is the first picture taken with this new setup.
Much better looking compared to my very first Double Cluster photo, taken over 2.5 years ago.

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

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).
