Never waste time of obervation ! California Nebula in H alpha - 42 minutes

When cooking, some people don't like to waste and use everything (I do). That's the same for imaging time in asttrophoto !

A few weeks ago, I was imaging the Cassiopeia region (ie. from Navi to Schedar), but around 4h in the morning, the constellation was hiding behind the roof of the house. I took the opportunity of the time left before the sun rise to image an object 2 hours higher in the sky : the California Nebula.

With the required time to aim this target (Skyguider Pro... no GoTo :-), I could grab 42 minutes worth of exposures over 2 nights.

NGC1499 is distant of around 1000 to 1500 ly, and 70x17 ly long and wide. More or less.

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.
