Imaging data:

Date: Nov 23,28 Dec 8,9 2010

Location: New Ringgold PA

Optics: Takahashi FSQ106 at f/5

Mount: Paramount ME

Camera/Filters: SBIG STL1000 Camera with Baader LRGBHa Filters

Guiding: Interal

Exposure: Luminance: 12x10 minutes R:12x10 min G:12x7 min B:12x10 min Ha:12X10 min all unbinned for a total of 9.4 hours

Processing: Image acquisition using CCD Autopilot. Initial processing was done using Maxim DL with subsequent processing using Photoshop. I combined the HA with both the Red and Luminance subs in Photoshop to create the Red and Luminance layers for this image to bring out more color and detail in the nebula.

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.
