M103 - Open Cluster

Link: http://kurt-zeppetello.blogspot.com/search?q=m103

Got another Messier Object on my quest of imaging all 110 objects (Messier Objects with an ED) with my Orion ED80. In addition stopped by the Double Cluster for a peak. M103 is located very close to Ruchbah, one of the five bright stars in the constellation Cassiopeia.

As a side note, I recently purchased the QHY-5L-II-M autoguider/planetary camera for autoguiding. So far I love this autoguider, it focuses really well on objects and quickly calibrates using PHD, even when moving on to different objects. See my recent post on the Autoguider at http://kurt-zeppetello.blogspot.com/2015/11/new-images-for-messier-quest.html.

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.
