Lobster Claw, Bubble, Cave, 4 panel mosaic (rflinn68)

Lobster Claw, Bubble, Cave, 4 panel mosaic

There are so many beautiful regions of dust, gas, and open clusters in the constellations of Cepheus and Cassiopeia. Even though this is a four panel mosaic shot with a 350mm focal length scope, it's still really just a small taste of all the different things in this area of the sky.

In the upper right of this mosaic is Sh2-155, the Cave Nebula. Below it in the middle-right portion is Sh2-154 with the small open cluster NGC 7419 just under it. The bright nebula near the bottom, left of center, is the Lobster Claw Nebula, or Sh2-157. Open Cluster NGC 7510 is in upper right part of the Lobster Claw. Just above and slightly to the left of the Lobster Claw is NGC 7635, the Bubble Nebula. Above and to the left of the Bubble is Open Cluster M52. The small bright nebula just left of center is NGC 7538.

This was shot over 4 or 5 nights from July 6th to July 12th. It is 30X600s per panel with the William Optics Star71 and SBIG STF-8300M set at -10C. I wish I could have cooled the sensor a bit more, but this was all the camera would do with the heat I was seeing then.

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.
