NGC 1499 in Pentax 150mm f6 SLR lens

Lying approximately 1000 LY from earth in the neighboring Orion arm of the Milky Way, NGC 1499 is 100 LY long and 60 LY wide. It is a glowing emission nebula comprising mainly of Hydrogen, which is energised by the bright star Xi Persei or 'Menkib' a blue giant.

Captured using my 2/3 mono CCD chip camera attached to an old Pentax 150mm SLR zoom lens, this image represents just over 4 hours integration with 5m subs. Gathered in Meade Envisage, calibrated and stacked in ASTAP and processed with Startools 1.8 alpha, using a standard workflow.

I'm pleased with the amount of detail, although surprised at the amount of noise - much due to a 99.7% moon, which tends to gradients in my Optolong L-eNhance filter. I could have swapped this out for separate Ha and OIII NB filters but wanted to try a single longer integration.

B

Description: This version contains top 60% of frames based on quality, as determined automatically by ASTAP. There appears to be less noise, which allowed a bit more deconvolution in Startools

C

Description: Another version with reduced stretch using non-linear DDP. The image feels smoother, although noise is still prevalent.

D

Description: Following a really helpful suggestion by @Lee, I have blended two versions (a brighter linear stretch with smoother DDP stretch) in Startools to produce this composite, which I think is the best compromise between brightness and contrast.

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.
