Wikipedia tells us that "Árvakr and Alsviðr in Norse Mythology are the horses which pull the sun, or Sól's chariot, across the sky each day. It is said that the gods fixed bellows underneath the two horses' shoulders to help cool them off as they rode "

So I am guessing that the Horsehead Nebula must be a mate of theirs

Taken on New Years Day 2021

Just one hour Ha and 25 mins Oiii ... synthetic green channel

I was going to wait until I had more data but ... its a lockdown Sunday and I'm bored

The main processing issue was the huge reflection of my Newts mirror round Alnitak which I think I have managed to tame ... the worst thing about the reflection is that it was bit offset which I assume means my scope wasn't very well collimated lol

Ordered two 20m repeater cables today so I can re site one of my scopes onto the lawn (if they work) as Orion and its glories is only unobstructed from the patio for a couple of hours a night

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.
