M42 from Bartlett Lake, AZ (Reprocessed)

This is a reprocess of my earlier M42 image taken from Bartlett Lake in AZ. The diffraction spikes are from stopping the lens down to f/7.1.

This image shows the true power of imaging at a dark sky site. Taken with a portable tracker and a stock DSLR, it handily shows more detail in the reflection nebula than the image I took from my Bortle 6 backyard with a light pollution filter - a 1.3 hour integration using a camera lens at f/7.1 outperforms a 3.4 hour integration using a cooled monochrome camera with filter wheel and an 80mm f/6 triplet! Dark skies are amazing!!

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.
