Total Exposure Time: 8 hours 4 panels of 2 hours each

June 2012; Inkom, ID

Comments: This region has fastinated me since I first imaged it in 2009. When I imaged Sh2-64 I immediately noticed a smoky or grey dust layer overlying the region . This layer had form and texture so I knew it was not a aberration of data processing and I figured it is a portion of the dark clouds cataloged as TGU (Tokyo Gakugei University) H279 P10,15,27 that I had defined. I also imaged other portions of the Milky Way in Serpens and also noticed some of this same dust cloud. This image above is a 4 panel mosiac, 2 hours per panel, showing this dust layer in better perspective. More exposure would be useful in reducing noise but alas, no time this month. I may add to this mosaic as time and weather permit.

This grey dust layer does take away from the overall contrast of the stars in this region, but I left the contrast purposely low so to better demonstrate this dust.

Some objects in this image are Sh2-64, LBN95, LBN96, LBN98, LDN588, vdB123, dark clouds TGU H279 P10, TGU H279 P15, and TGU H279 P27, and Sh2-69 way down in the lower right corner.

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.
