The Bubble Nebula, The Lobster Claw Nebula and The M52 Cluster

So much happening in this region with the M52 Cluster, The Bubble Nebula NGC7635, the emission and reflection nebula NGC7538 and Sharpless 157 or otherwise known as The Lobster Claw Nebula.

This 4 degree x 2.65 degree image was captured during September of 2014 from my backyard observatory in Fremont Michigan and viewed here in Color using RGB + H-Alpha filters and processed with RGB and H-Alpha as luminance. The Hubble Palette version is using data from the color version for the naturally colored stars. In both cases I used data from a capture last year using my 12 inch Ritchey-Chrétien astrograph for the Bubble Nebula.

The equipment I use is the QHY11S Mono CCD and a Takahashi E180 Astrograph.

Total Integration Time 214 Minutes (not including the 26 hours from my old data)

Here is the data I used for the Bubble Nebula only (Color and Hubble Palette)

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.
