Jupiter: The First Try of WinJupos

This is my first try of WinJupos: a program, that eliminates an effect of the rotation of a planet (if the effect is quite small) and allows to combine images taken during some period of time to improve a quality of the resulting image.

Three clips taken on 17th of May (with SW15075OTAW + Tele Vue Barlow x3 (1.25") + Canon EOS 600D) were recorded at 21:56, 21:59, and 22:03 UT+3 (times correspond to the end of the recording of each clip).

Those clips were processed using AS!3 and Registax6 (15% of 3600 frames for each clip were stacked and sharpened with wavelets).
Then the resulting images were derotated and compiled into the final image with WinJupos.
Finally, the image was additionally sharpened in Registax6 and postprocessed in FITSwork4 and RawTherapee.

Saturn

SATURN from Kyiv on 18-Jun-2017.
Planet's altitude was about 15*.

Setup: Sky-Watcher 15075 OTAW / EQ5 + Barlow TeleVue x3 + Canon EOS 600D
Processing: PIPP (4 movies, 4500-5000 frames); AS!3 (RGB align, stacking, 15% of frames from each movie used to generate images); Registax6 (wavelets); WinJupos (4 images de-rotated and compiled together); Registax6 (again, wavelets)

The largest Saturn's moon Titan is barely seen in the following image (single movie, Titan is made brighter):

Comet C/2015 V2 (2)

Time: 2017-06-09 23:53 .. 2017-06-10 01:17 UT+3

Kyiv

Moon was full (99.9%) so the background was severely highlighted.

Setup: Sky Watcher 15075 OTAW on EQ5 with motor drives (no guiding); Canon EOS 600D

89 light frames 30s each; 21 offsets; 21 darks; 18 flats.

Processing: IRIS (calibration, stacking by the comet); postprocessing: FITStacker, FITSwork4, RawTherapee

North: up, West: to the right.

Animation (the same 89 frames; calibration and alignment: DeepSkyStacker; postprocessing: RawTherapee, FSViewer, VirtualDub)

Supernova SN 2017eaw (2)

Supernova SN 2017eaw in a galaxy NGC 6946 (Fireworks Galaxy) is still shining as billion suns (the supernova is marked by green dashes -- see the second picture beneath). The galaxy is distanced from us at approximately 22,000,000 light years.

Most of the stars in the picture (except the supernova) belongs to our Milky Way. An open star cluster NGC 6939 is visible in the upper right corner (a distance to it is about 4,000 light years).

A picture was taken in the night 27-28 of May 2017 from Kyiv.

Setup: Sky Watcher 15075 OTAW / EQ5 motorized (no guiding) + Canon EOS 600D @ ISO=1600.

There were 91 light frames in total @ Tv=30s (total exposure 45.5 min) plus 21 darks, 21 biases, and 10 flats.

This is a combo image: synthetic L-channel overlapped by RGB image.

Image size: 47,3x47,3 arcmin [nova.astrometry.net]
