NGC 4565

NGC 4565, the Needle Galaxy, is a beautiful edge on spiral approximately 43 million light years from earth. This is the first target captured with my SW Quattro 300P newtonian, taking advantage of my recent mount upgrade to swing a larger scope. With this addition I have maxed out my travel image capacity with the scope, mount, tripod and counterweights exceeding 200 lbs. Batteries, cases and miscellaneous gear take the to total over 300.

So far I am really enjoying the Quattro as with the matching coma corrector the scope is producing a very well corrected field across the entire frame on my 1600MM. Finally the stars have a nice profile and color saturation I never could get with the C11 I used previously for galaxies. The speed of the Quattro (F4) is also a big help as my imaging time is quite limited. I did make a mistake on my initial Lum subs as gain 0 for 60 seconds did not swamp the higher read noise. As a result I had to clip the background a bit hard to remove some nasty fixed pattern noise. Switching to gain 50/60s fixed that issue, but to late for this image.

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.
