A dusty Veil Nebula (Robin Livermore)

A dusty Veil Nebula

Revision title: with added OIII data

I had a vague plan to shoot the Veil in broadband this summer, and was spurred on by seeing an image that showed off plenty of dust beyond the Western Veil. I'm afraid I can't remember or locate that image to give credit. Anyway, as a result I went big, and this is a 6 panel mosaic. I've only managed to gather a fairly paltry amount of data, but I used the only 2 moonless nights with any clear sky here in August, and the weather has been so poor for weeks, I just decided to finish and move on to other targets (if we get any clear nights in September!). One panel has only 20 minutes of data - less than half the other five, and maybe not really enough for the dithering and drizzle that I applied. But I can't really spot the difference after processing - if you want to guess which panel, please do!

The brightest part of the dust to the North West is catalogued as LDN864. The strange tadpole like thing to the south of it (which I also published separately) is LDN846. A nice spiral galaxy NGC7013 sits to the East, and above it an interesting shaped dust cloud, uncatalogued, perhaps reminiscent of the Ghost Nebula. As for the Veil, it's bright, so even in broadband it stands out well with starless processing. Perhaps unsurprisingly the Ha is stronger than the OIII though, so some of the blue filaments you would normally see are barely visible. I could look at supplementing this, maybe using old narrowband data, but I don't want to spoil the rest, so for now at least I'm happy with it as it is.

Final version is enhanced with 5h 28m of data from a dual narrowband version of the Veil I shot in 2021, but only the OIII in the Veil is enhanced.

Description: I had to do some masking to prevent the Veil blowing out too much when stretching the dust, and there was one little bit I wasn't happy with, so this revision just sorts that out

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.
