Utah Astrophotography
Heart and Soul
Over the last month I've been cranking away on my telescope, weather has been cooperative during nights when the moon is up of course. So I've been using my Optolong L-enhance filter with my Nikon D5300, collecting 10 minute exposure after 10 minute exposure. I've collected quite a bit of data on several targets, finally finished a 3 panel mosaic of the Heart and Soul Nebula. Not perfect, still learning how to properly combine bi-color shots with Pixinsight and the Oiii response from a DSLR is very very difficult to integrate. This is a notoriously tough target for a DSLR as well, especially narrowband and especially during a full moon.
All in all this is 25 hours of exposure, 3 panels shot with a Nikon D5300 (modified) and Astrotech AT65EDQ telescope on a Sirius EQ-G mount. Each panel is a stack of 50 x 10 minute exposures at ISO 200. All the calibration, stacking, background extraction, stretching, channel combination, and curves manipulation was done in PixInsight. A slight star size reduction was performed in Photoshop.
