Processing information:

This image was taken with a prototype of an on-axis guider, which has a mirror that reflects the visual image light to the camera at a 90 degree angle, while allowing IR light to pass through to the inline guider. It works well and gives a very good FOV for the guide camera.

Date: May 30 - June 8, 2011

Location: New Ringgold PA

Optics: Hyperion f/8 12.5 inch, FL 2540 mm

Mount: Paramount ME

Camera: Apogee U8300

Guiding: ST-402 on Innovations Foresight On-Axis Guider

Exposure: LRGB: L:23x10min R:17x7 min, G:14x5 min, B:18x8 min

Processing: Image acquisition using CCD Autopilot. Initial processing was done using Maxim DL with subsequent processing with Photoshop.

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.
