Witch Head Nebula, IC 2118

I only posted this as an example of what can be done with very little exposure time and a whole lot of dew! I was travelling and didn't have my dew heater with me, and after two hours of imaging there was heavy dew buildup on the scope's objective lens. I had to throw away the 2nd half of the subs, which helped, but did not completely eliminate the effect of the dew on the final image. Despite all that, I'm pleasantly surprised at how this turned out.

The Witch Head Nebula is a very faint reflection nebula in Orion (abs. magnitude 13). It's illuminated by the supergiant star Rigel (outside the view of this image). In this image, some of the light from Rigel can be seen streaming toward the Witch's nose (upper right).

Clear skies!

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.
