NGC 7822 - Cosmic Question Mark Nebula

I have wanted to break the 100 hour mark on a project for a while now, and I've finally done it! Here's 109 hours of exposure on the center of the huge Cosmic Question Mark Nebula, shot over nine hot August nights with my twin rigs. This image was processed in the classic SHO Hubble palette and finished with RGB stars.

The Oiii data was shot at my brothers house in a B7 suburban area and the rest from home in B9, bang in the middle of Houston. I had previously only shot from B9, or B1-4, and was shocked at how much better it was shooting from just 30 miles away in B7. It made a massive difference on the Oiii channel.

Each master channel was processed with 2x drizzle and finished with Bill Blanshan's brilliant new star reduction scripts for PixInsight. Those are free and highly recommended. He's got a pair of informative videos about both the Star Reduction and Screen Stars scripts that were helpful.

Clear skies,
Chris

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.
