Sadr in Ha

Captured over 2 nights a day before and a day after the full moom. I wanted to test out the mosaic feature in the latest V2 update to the ASIair pro. A simple and easy feature to use. select you target of choice, set 2x2 / 3x3 ect for framing of the mosaic, export as a plan. Set plan with the filter, number of images and duration. Done. Result is 24 x 5 minute Ha exposures in a 2 x 2 pane mosaic with a 25% overlap. Processed with pixinsight, calibrated and Histogram transormation stretch and EZ de noise. 2 verions one with and one without stars.

The Pleiades is always a favourite from Autumn to spring, 2020 saw a few different compositions. from a conjunction with Venus to an unfinished multi panel mosaic.

 

Lunar Mosaic

This is my first attempt of a lunar mosaic imaging with the 90mm refractor. Using the prevoiusly mentioned DSLR avi capture programme. Thursday evening saw an hour or so of clear skies just before the low moon drifted behind the roof of the house. Using the amazing live view zoom mode I am capturing HD avi movies and utilising registax 6 to process and stack. I used the same wavelet setting on each of the 5 images. A few pixels were removed from the sides to remove unwanted artifacts and colour fringing from the stack.

camera was set to Iso 800 and 1/60th sec exposure.

I think it came out alright.
