Nova Cassiopeiae 2021

I love events in the sky, and the nova in Cassiopeia qualifies. Unfortunately it isn't well positioned for observers outside of the far north. In Austin it clears the muck on the northeaster horizon about an hour before astronomical dawn. Once again I took advantage of the Optolong L-eNhance filter to cut through light pollution.

I'm not where I want to be in processing the final image, but this blinking GIF version was fun to make and subject appropriate. Nova V1405 Cas has very photogenic company including the M52 open cluster and the Bubble Nebula, NGC 7635.

Can you find the blinking (solely to indicate its position) nova? A larger size GIF animation is linked.

The image has 60 minutes of 3 minute light data integrated from a William Optics RedCat 250/51 mm telescope, Optolong L-eNhance filter, ZWO ASI-533 MC camera cooled to -10C. Processed in PixInsight, Topaz DeNoise, and Photoshop.
