M46 - with 81% moon - with cropped option

Last night defied all forecasts and remained clear for most of the evening, so I was greedy to make best use of the opportunity, and imaged four different objects in one night, just to see how I got on! This is the first of those images, with only 34 subs taken. The gradients, even with PixInsight's amazing tools, were very tough with strange banding across the image background, which I can only put down to the sky being bathed in moonlight - well I hope it is that! I also think that the RASA at f2 is drawing in so much light that this exacerbates the background issue that I'm referring to... I want to keep using this telescope but the reality is now that I'm in galaxy season, I need to go back to the RC. It's pretty much full moon now but I'm going to have a crack at M63 tonight, if I can.

I am pleased to have caught so many objects (7) in one frame, including a very small extra planetary nebula (directly south of the M46 cluster and the planetary nebula NGC 2438, and just to the right of those). Thanks everyone....

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.
