M97 and M108

M97(Owl Nebula) and M108 in Ursa Major.

M97 - The owl nebula is a Planetary Nebula and is one of the only 4 of this type in the Messier catalog. This is the blue/red object on top left of the frame. This is one of the fainter object (at >Mag10) to photograph.

The planetary nebula (a misnomer with nothing to do with Planets) is formed when a smaller mass star (like roughly the size of our sun) runs out of fuel and dies. The outer layer of the swollen star are blown off creating the halo leaving behind a hot/dense white dwarf.

There is an even fainter halo that is not visible here but can be imaged with longer integration time in narrowband wavelenght.

On the Bottom right is another Messier object (seperated by only 50 arc minute ) is a spiral galaxy almost seen edge on. Though it looks closer to M97, they are not physically close. The M97 is in our galaxy and M108 is a completely different galaxy.

After multiple months, we had 3 clear nights! I had my Takahashi + 1.6x extender loaded, I could go after multiple target fields and this one fit nicely.

Equipment: Takahashi FSQ106ED + 1.6 extender making it a F8/800mm FL scope/AP900 Mount/FLI HP8300 with Baader LRGB filters.

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.
