Tonight’s “supermoon” on ABC Science

Today I’ve been interviewed in ABC Science about the “Supermoon” that we can enjoy tonight, 7th May 2020. For this we have used some of the images of the moon that my son and me have been taking during the last year.

I want to thank Genelle Weule for the excellent questions and for her great interest about astronomy and astrophotography.

Comet C/2020 F8 (SWAN) over Sydney

Comet C/2020 F8 (SWAN), Sydney, May the 4th, 2020, 5:15am

Image combining 10 x 2min exposures using an Optolong L-Pro filter, Skywatcher BD80, focal reducer Orion x0.8, ZWO ASI178MC. Mount Skywatcher AZ-EQ6 Pro mount, camera ZWO ASI120MM for guiding and ASIair for controlling everything.

Individual frames dark subtracted with Siril software, then I did the alignment on the comet manually in Photoshop (that is why stars are moved and blurry, as stacked with median), where I also played with the color/brightness/contrast.

The top image is the resulting color image, the bottom image is the greyscale image increasing the contrast to increase the visibility of the tail and the faintest features.
