NGC 6888 | The Crescent

A deep view of the Crescent Nebula reveals not a crescent, but the full Wolf-Rayet bubble system of WR 136.

This is the first data I've captured after spending three days installing a Planewave L-350 mount to carry the CDK14. Balance issues are critical with this mount, and I'm likely to go back to completely reconfigure the setup and improve balance and polar alignment.

While I cannot shoot unguided at this time, with guiding I've gotten some of the sharpest subs in years here. Luckily our sharp Summer nights promptly started the night I turned the new mount on!

Ha and OIII where combined (Ha) / (Ha*.1+OIII*.9) / (OIII - Ha/10) for a roughly HOO mix. I shoot RGB stars but decided I liked these NB stars more.

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.
