NGC7822 and SH2-170

This was the last image taken with the Askar300 since the clouds rolled in at the end of October. I had to re-image the stars twice as the first set suffered from severe pinched optics at -15C. I had to put an additional dew heater at the back end of the scope over top the focuser to heat up the rear element. This seemed to work and minimized the effect of the pinched optics. The Cosmic Question Mark comprised of NGC 7822 and SH2-170 is a bright target which is visible all year round for 54 degrees north. To me the entire nebulae complex of NGC7822 looks like a primate skull. Two big eyes looking to the left? maybe I have been looking at he image for too long and started seeing things that are not there. Went with a "natural" colour compbination with the narrowband data. I see a lot of Hubble palate with this target so I thought of something different with this version. Hopefully some clear skies soon, going on nearly 4 months without a star.

CS to all

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.
