M17 in Hubble Palette crop

Known as The Omega or Swan Nebula and also The Checkmark, Horseshoe and Lobster Nebula.

This is a crop of the original. Not nearly enough data and the object was less than 20 degrees above the horizon when I got the remainding SII data but it will have to suffice for this year

I didn't think I'd be able to add any color at all this year but last night I was blessed with a few hours of clear sky which allowed me to complete this and complete another project I have been working on. Now we are back to cloudy and cold conditions once again.

Captured over 3 nights early October 2012 shot at native resolution (F5.5)

Total Exposure time 5 hours.

Location: Fremont, Michigan

Date of Shoot 1st, 3rd and 8th October 2012

All exposures unbinned

H-Alpha 3nm 8 x 20 min

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.
