M16, Eagle Nebula, BAD!

About everything that could go wrong with this image did go wrong: clouds, wind, out of focus, clouds, thunderstorm, clouds, poor guiding, not enough time on target, clouds. Nevertheless, I'm trying to frame tighter without the focal reducer and in between the clouds it looks like the mount can probably handle this if conditions are better.

Date: 24 Jul 2012

Subject: M16, Eagle Nebula

Scope: AT8IN (no focal reduction!)

Filter: none

Mount: CG-5 (Synta motors)

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

Camera: DSI IIc

Acquisition: Nebulosity 3.0.8

Exposure: 2 x 300 s (yes, that's all I got before clouds and focus shift REALLY wrecked things)

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

Processing: auto color balance, digital development with sharpening, Keller stretch, power stretch. In separate layer, GREYCStoration. To the denoised layer in CS5, Astronomy Tools deep space & space noise reduction. To the "sharp" layer, AT local contrast enhance. Combine with Gaussian blurred layer mask. Saturation boost.

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.
