2019-06-04 IC1805 The Heart Nebula

I imaged the Heart Nebula on November 20 and 26, 2017 from Buford Mt Conservation Area. I had not processed the image earlier because it has several issues, including flared stars at the edges and poor focus on the color frames. Since I have not re-imaged the object, and with the persistent bad weather, I decided to process the data.

IC1805 the Heart Nebula imaged with an 80 mm aperture, 480 mm focal length apochromat with 0.8x focal reducer for 384 mm focal length, QSI 683wsg-8 camera having Astrodon Gen II Ha filter, on a Celestron AVX mount, autoguided. Total exposure time of 5 hours. Processed in PixInsight.

Ha: 10 x 30 min

This color version is a total exposure time of 9 hours 20 min. Processed in PixInsight. Ha: 10 x 30 min; Lum: 8 x 10 min; R, G, B: 6 x 10 min

The dark clouds are dense gases and silicate dust in more advanced star forming stages. They are swept back by the “wind” from the central star cluster.

The small, black, round region below center is a “Bok Globule” (named for the Danish astronomer Bart Bock), which is the final stage of new star creation.
