M100 and surrounding galaxies

Conditions still less than ideal, but a shot at a new object anyway! It was too late at night when I did the original processing. I re-did it to bring up the faint fuzzies a bit better. I really should have integrated longer, but I was having cable hang-up issues I couldn't fix easily.

Date: 7 May 2012

Subject: M100 & surrounding galaxies

Scope: Meade 4501, 0.5x Antares telereducer

Filter: none

Mount: CG-5 (Synta motors)

Guiding: Orion ST80 + 0.5x Antares telereducer + DSI Ic + PHD

Camera: DSI IIc (cooled at 2 A, 6.0 V)

Acquisition: Nebulosity 3.0.3

Exposure: 19 x 300 s

Stacking: Neb 3, bias included, normalize first, align, 1.5 SD stack

Processing: Digital development with sharpening, power stretch and Keller stretch in N3, CS5 GradientXTerminator, levels, curves; Astronomy Tools noise reduction (space & deep space), color blotch reduction, star size reduction, local contrast enhance; CS5 feathered levels of background, healing brush to fix bad pixels.

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.
