Supernova SN 2017eaw

Supernova SN 2017eaw in Fireworks galaxy (NGC 6946). 

The supernova is marked by green dashes (to the upper-right from the galaxy).

Other stars (visible in the picture) belong to our own galaxy, Milky Way.

Captured near local midnight 20-21 May 2017 from Kyiv.

Setup: SkyWatcher 15075OTAW/EQ5 motorized (no guiding), Canon EOS 600D

95x30s ISO=1600

Processing: IRIS, FITStacker, RawTherapee, FITSwork4

Moon and Jupiter near Conjunction

Moon and Jupiter 10-Apr-2017 at ~22:50 (UT+3) from Kyiv.
To the left and below Jupiter is θ Virginis.
The four Galilean moons are lined up: Io, Ganymede, Europa, Callisto.

This is a combination of three different exposures: 1/2s for Jovian moons, 1/128s for Jupiter itself, and 1/640s for Moon.

The camera [Canon EOS 600 D + EF-S f/4-5.6 55-250 IS II] was mounted on EQ5 with motor drives.

Comet 41P (TGK) Remastered

Images of a comet 41P in my previous post were processed with DeepSkyStacker. It is a very good program to get a quick-and-dirty result of an astrosession. Hovewer, I always got a better output with another free astrosoftware: IRIS. I've never tried to process comet's images yet with IRIS so it is my first attempt to use the special comet-tracking functionality of it.

I reprocessed the same set of frames as in my previous post: 50 frames x 30s, taken at ISO 800 using Canon EOS 600D attached to SkyWatcher 15075 Newtonian on top of motorized EQ5 mount (no guiding). I used 19 dark and 19 offset frames for calibration.

The frames were captured between 23:23 and 23:54 local Kyiv time (UT+3) on 2 Apr 2017.

I should say that IRIS gave a less noisy picture; comet's coma is seen better. In general, the image looks "softer" and "more natural".

A size of the cropped image is 45x45 arcminutes.
