Veil Nebula as seen over multiple sessions during the Summer of 2014. Data was collected starting at GSSP and through several nights at Montebello Open Space Preserve in July and August.

Total of 24 sub exposures for 8 hours of integration. Many near-overlapping frames made it difficult to properly align the images to eliminate transparency differences.

Stellarvue SV scope with SSF6 flattener, IDAS HEIUB-II filter with Pentax K10D (modified and cooled) dslr.

Calibrated with Maxim, Stacked in DSS, Processed in PixInsight.

PI work was pretty easy, given the clean source. Didn't need to do a lot of noise reduction, just a little in ACDNR. I normally use the Denoise tool, but the masking was proving too difficult for my skills with too many stars and the faint nebulosity. Tighted up the oblong stars with Deconvolution tool.

The oblong stars are my returning challenge regarding what might be flexure. Still trying to nail this once down and I may have to struggle through Calstar with this problem.

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.
