Wow wow wow! New to the Newt Club, I set up last night in the hopes of just a few hours as the forecast was a bit hit and miss for my area, but really wanted to try and make a good first image, not just a test image. Ended up setting the big rig off for 5hrs worth of imaging and went to bed. Woke up with the scope parked and the entire imaging run complete including flip. Happy days. Checked the data when I got back from work and only had to toss 2 subs out of 150, looks like it was due to not settling after a dither. Guiding averaged 0.81" over the whole run, moderately balanced and there is some backlash developing in the mount, so happy days again. I took flats this time as well in the hopes of it calibrating out that nasty halo, and job done. Cropped in the edges where it didn't quite flip and frame itself properly, and here is my result...

It's 130x120s sub frames for 4hrs 20mins of exposure. Shot with the ASI533MC-Pro, UV/IR Cut, SW 250P Quattro @F/4, mounted on the EQ6-R Pro, guided OAG by ASI290MM-Mini, manual focus and sequenced by ASIAIR Plus. Stacked in DSS and processed with PS.

Yet to fit the EAF, properly collimate the scope, and properly seal it against light leaks, but I'm very pleased with this indeed. I'm amazed at how it's picked up those faint tidal arms with a relatively low integration time in a moderately light polluted sky!

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.
