M34, NGC1039 Open Cluster

Messier 34 NGC1039 is a lovely open cluster in the constellation Perseus some 1,500 light years distant, with an estimated 400 member stars. It subtends about 35', one moon diameter, giving it a radius of about 7 light years.

From a paper: SPECTROSCOPY OF STARS IN THE GALACTIC CLUSTER NGC 1039 (M 34) PHILIP A. IANNA° The Ohio State University Received March 23,1970

The brightst members of this cluster are B-type main-sequence stars (B V). B-type stars are extremely luminous and blue. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K.

I had some extra time in the early evening and decided to finished data collection that I started a few years ago still only a few frames six each RGB for (18) total. This combines data from 2012 taken while camping at 9.000' with remote observatory data taken more recently. All integration used the home made 8" F/2.6 astrograph.

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.
