NGC4565 - The Needle Galaxy

It has been a slow late winter/early spring for imaging here. I spent most clear nights in March working on the big scope and collecting data for this project. I really am enjoying going after edge on galaxies lately. This is the first project having my camera set to 0 gain. Honestly I have not seen much difference compared to my last couple projects at gain 1600. But the math does say it is better. The only thing I did notice is horizontal banding in the calibration frames and the stacks for each channel. The banding was barely there, maybe a few ADU above the background. So after processing it is not visible.

I was a little bummed to pour over 18hr into H-alpha data for this and not really get anything. Meaning there really isn't much H-alpha data in the galaxy like we see in face on spirals. Though the whole galaxy does show up. Just no HA pockets of gas or jets.

Seeing was all over the map on this one with nightly averages from 2.09"->4.36" (taken via SBIG SBS SM-2 monitor). Actually the last night I was collecting data the first have was hovering around 1.2" and at times a touch below 1". Ever since I got this seeing monitor, I realized my scope is likely the limiting factor and not the location. So I am continuing to improve this 12" to produce the best raw data I can. To that end, I have acquired a small CNC machine to cut custom aluminum parts. First big project is a one-piece spider similar to what AstroBackyard makes, but bigger and beefier.

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.
