California Nebula Mosaic in Ha (Deep Sky West (Lloyd))

California Nebula Mosaic in Ha

Experimental image. A 2-panel mosaic of the California Nebula in Ha only. The framing is not one that I've seen too often so hopefully it's a somewhat unique perspective. This framing is primarily due to the camera/scope combination and limited time. For now, as a good friend recently told me, mosaics are way more cost effective than the big chip camera that I covet...so here it is...

The weather at SRO has been decidedly uncooperative for a couple of weeks with the exception of last night and fortunately this target is placed so that it can be imaged nearly the entire night. Thus, this incomplete mosaic of 8x1800 and 5x1800. Our usual standard for this imaging set up is at least 16x1800 in Ha, but given the brightness of the target there was something to work with. No flats were applied.

I used the standard approach to creating the mosaic with StarAlignment and GMM. I also used DrizzleIntegration just for kicks. Fortunately, the panels lined up very well in this case (plus there are only 2....a much more ambitious 9-panel mosaic is still in the works).

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.
