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.
This is a 2 panel mosaic of the North America and Pelican Nebula shot with a modified Nikon D5300 (plus Optolong L-eNhance filter), Astrotech AT65EDQ Telescope on a Sirius EQ-G Mount (Rowan Belt Modified). Each panel is a 50 x10minute stack of exposures at ISO 200, images were acquired with BackyardNIkon/Sequence Generator Pro, guiding performed with PHD2 (dithered every frame), editing performed in PixInsight.
This is a difficult target with moderate amounts of light pollution, from where my mount is setup I only get a ~2-3 hour window to shoot the nebula this time of year and give the light pollution in the area I really need to get 15 hours of integration or more. This is a stack of 87 x4 minute exposures for a little less than 6 hours total, if I get some clear skies during the new moon phase I want to get at least double that to bring the noise down and more of the details out. Nikon D5300 (modified) with an Astrotech AT65EDQ telescope on a Sirius EQ-G mount (Rowan Belt Modified). 87 x5 minute, ISO 400, calibrated with flats and bias, stacked, and edited in PixInsight with final edits in Photoshop.
