IC 1805 & Sh2-199, Heart & Soul Nebulae, Quantaray OSC Hα, 31 Oct 2015 False Color Animation

The animation will require about 5 seconds to start

Realized I could get the Heart & Soul Nebulae together with the Quantaray zoom lens set at 90 mm, so this is my attempt. Good conditions on Halloween night. Had a lot of trouble getting a good plate solve and getting good focus; you have to find a bright star to focus with this lens and the Hα filter. Eventually I plate solved with my finder to get close, then used that to get a bright star in the field of my imaging camera. I started getting drift/differential flexure near the meridian (I had gone to bed so wasn’t around to fix it). This image greatly benefitted from 3x drizzle stacking in Deep Sky Stacker.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
