89% waxing, gibbous Moon with AstroDMx Capture for Linux

Four overlapping panes of the Moon were captured as 2500 frame SER files at maximum resolution of 1280 x 960, using AstroDMx Capture for Linux, running on a Debian laptop, with an f/5, Skywatcher Explorer 130 P-DS OTA Newtonian and a QHY-5L-II-M camera, fitted with a 2" adapter and a 13% transmission neutral density filter, mounted on a Celestron AVX, EQ, GOTO mount. The best 40% of the frames in each SER file were stacked in Autostakkert! running in Wine. Each of the four resulting images was wavelet processed in Registax 5.1 running in Wine and the resulting images were stitched in Microsoft ICE also running in Wine. The final Mosaic image was processed in the Gimp 2.9. Click on the image and click again to get a closer view.

80% waxing, gibbous Moon with AstroDMx Capture for Linux

A Skywatcher Explorer 130 P-DS OTA Newtonian and a QHY-5L-II-M camera were mounted on a Star Discovery AZ GOTO Mount. AstroDMx Capture for Linux was used with Debian Linux to capture 4 overlapping 1500 frame SER files of the Moon at maximum resolution. The best 50% of the captured frames were stacked in Autostakkert! 3 running in Wine. The three resulting panes were wavelet processed in Registax 5.1 and then stitched into a 4 panel mosaic in Microsoft ICE, also running in Wine. The final image was processed in the Gimp.

The Orion nebula with AstroDMx Capture for Linux

100 x 5s, 16 bit Tiff files were captured of The Orion nebula with UHC filter with 100 matching dark-frames, using AstroDMx Capture for Linux with an f/5, Skywatcher Explorer 130 P-DS OTA Newtonian and a QHY-5L-II-M camera, mounted on a Celestron AVX, EQ, GOTO mount. The images were stacked and dark-frame corrected in Deep Sky Stacker running in Wine. The final image was processed in the Gimp 2.9.

Star Party at the National Botanic Garden of Wales Sat. November 25

The afternoon activities were only attended by few children, but they were able to view the Moon through telescopes and in the early evening.  By dusk we had  at least 70 children and 60 adults.  and between the occasional light rain showers further Moon views were possible.  There were several films shown on the big screen, Brian Spinks did one talk for the youngsters and another for adults.  There were plenty of Telescopes on display and lots of displays of Meteorites and other objects. Jim and Anne Startup helped show one of our members how to use his scope.  Andrew Sprott was there with his displays as was Phil with the SAS ones.  And Alison and Megan helped out with their activities.  A very successful evening.

31% waxing, crescent Moon with AstroDMx Capture for Linux and a QHY-5L-II-M camera

A Skywatcher Explorer 130 P-DS OTA Newtonian and a QHY-5L-II-M camera were mounted on a Star Discovery AZ GOTO Mount. AstroDMx Capture for Linux was used with Ubuntu 17.10 to capture 2 x 1500 frame SER files at maximum resolution. The two SER files overlapped. Autostakkert 3 was used to stack the best 80% of the frames in each SER file and Registax 5.1 was used to wavelet process the two resulting overlapping panes. The two panes were stitched into a single image using Microsoft ICE. All three programs were running in Wine. The final image was post processed in the Gimp 2.9. Click on the image to get a closer view.

M2 and M27 with AstroDMx Capture for Linux and a QHY-5L-II-M

16 bit Tiff files were captured of M27(50 images) with UHC filter and M2(80 images) with LP filter, with matching dark-frames, using AstroDMx Capture for Linux with an f/5, Skywatcher Explorer 130 P-DS OTA Newtonian and a QHY-5L-II-M camera, mounted on a Celestron AVX, EQ, GOTO mount. The images were stacked and dark-frame corrected in Deep Sky Stacker running in Wine. Fits files were produced and processed in ESA, ESO, NASA Fits Liberator software running in Wine. The final output Tiff images were post processed in the Gimp 2.9.
