NGC 3718 with NGC 3729
Posted: Tue Mar 29, 2022 2:19 pm
I know: again a capture?? 
We had a streak of clear nights here, so I could work on my list. This was on there: NGC 3718 (on the right) with NGC 3729.
A nice pair at around 59 million lightyear which is part of the Ursa Major Cluster.
NGC 3718 is thought to got his particular shape due to gravitational interaction with NGC 3729 in the far past.
The small cluster of 5 galaxies below NGC 3718 is called Hickson 56 and is around 400 million lightyears.
It was a tough capture though and processing due to the position. It's in a part of the sky where somehow the light pollution here is not in my favour.
But it is what it is, so I'm happy with the result
Bortle 6/7
Meade LX200 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Baader IR/UV Cut filter
Baader Neodymium Skyglow filter
