M44 and Fuzzies in the Background

The most important thing in trying to operate a Tak E series scope is the focus. This image is not quite there. After three years I have finally been able to collimate it and somewhat adjust for tilt. The ASI 294 is being operated in native un-binned mode which makes things more difficult. What I found was that what I thought was collimation and tilt was not quite collimation and tilt. Instead, most of the issue was focus. If you are not spot on with a hyperbolic Newtonian reflector your images are going to look like crap with different optical aberrations. The issue is compounded by the camera which has 2.45 micron pixels. If you can get a clean image with this combination you can probably tweak just about any rig available today. Very difficult scope to operate and coupled with a super small pixel camera, almost impossible. However, after some persistence, I am getting closer. The next image will be with full attention placed on focusing and hopefully it will be even better.

There are quite a few fuzzies in the background which are distant galaxies and are very faint. I went after these with the longer exposure, but the resolution is not quite there. I bet my Stowaway can do a better job on these items, or ultimately when I conquer the focusing and final tilt and collimation adjustments I will be able to better resolve these un-named glaxies.

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.
