The Horsehead Nebula

This was imaged on the 9th,11th and 12th of October 2015 at about 1030 UTC time very early in the morning at maximum altitude from my location at about 40 degrees . The sky was a 10 out of 9 with transparency at a 5 out of 5. It just is simply worth driving to a dark location even if 400 miles away one way. I stayed in a log cabin for a week at the Heppner OHV park in Oregon and had a great week of imaging. My only problem day was the last night on the 14th with the most amazing clear sky I have seen ; except for one major problem. Now what would that be?? The mirror lens completely frosted up and was also drenched in dew. All when the scope was tracking at its very best with 5 minute unguided subs. Normally in N.E. Oregon humidity is very, very low all night thus I did not bring my dew shield with me on my trip. This turned out to be a very bad idea and next time I will always carry it with me in my car from now on.

Additional data was collected on 111115 at The Chiefland Star Party in Chiefland Florida from 24 subs of 2 minutes each. I took advantage with The Horsehead up an additional 12 to 14 degrees in the sky. To bad I only had one clear night to shoot from. Well maybe next time I'll get additional data from a different site this winter.

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.
