Needle galaxies

There are a whole lot of galaxies in Virgo, and among them there are nice although small spiral one - NGC5364. This one and its neighbours I have chosen some time ago for a frame. Photons were collected at the end of April, 2016 from my suburban backyard - it is total 450 minutes of exposition (with 5 minutes single sub). There are several needle shaped galaxy also in the frame - these are viewed from the edge.

And the luminance channel only annotated (watch the 1.1 billion light years distant galaxy cluster to the right):

Hunt for TrES-3b exoplanet transit

Nights in June are very short in central Europe - not even three hours. Fortunately the TrES3-3b exoplanet minimum lasts only about hour and on the June, 5th I managed to record the minimum. The egzoplanet traversed between the star and us and it caused the very small star brigtness reduction - about 0.02 magnitude, that is near the limit of detection of my setup. But, eventually, exoplanet transit has been recorded:

Lightcurve

TrES3 star position
Gears used: TS130/910 refractor with 0.79x reducer, Atik383 mono camera with Baader L filter, EQ6 mount, OAG guided. Single exposure - 120 seconds.
So - exoplanet detected from the backyard - yay !

Clear skies!

Mixed location Whirlpool

160 minutes of luminance made in Zatom. 120 minutes of RGB made in Nieborowice. Some time for processing, and here it is - M51 - Whirlpool galaxy. One of the icons of night sky, impressive spiral galaxy seen en face together with its smaller company - NGC5195. And decorated with some stars plus a few fainter fuzzies.
