NGC 1499 California Nebula

I needed this one. Too many of my recent projects have not turned out as I hoped. I was not expecting a lot from this data set. I was shooting a much bigger project, and I needed a target to finish off the night so I set up NGC1499 in SGP as an afterthought.

This is an HSS image taken through my 200mm NikkorQ lens. This lens dates from the 1970s I think, but it produces fairly good images wide open at f4. Of all my eBay lenses purchased when I got into this hobby, this lens is my favourite.

There is a very circular arc near the upper left of this nebula which I thought was a lens artifact. However the same arc appears in NGC1499 images taken by others. I wonder if this arc is something real or just the human mind trying to see a circle where there is not one?

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.
