M33 Triangulum galaxy in LRGB

What should be first light with my new ASI 294MM Pro camera is now a second light. The first night, I only had two hours of luminance data before the clouds rolled in. But the subs were really beautiful. So last night, I wanted to collect all other stuff that is needed for an LRGB image. But how life goes, conditions again were by far not perfect. There was a really strong wind and it was fighting against my 8" Newtonian scope with its dew shield on it all through the night. It was hard to keep the guiding under 2,5 arcseconds the whole time which was the worst I ever had. But I did not give up and ended up with some data. Never would I expect to get a reasonable image from that data.

But I was really surprised how wrong I could be. I processed this image of M33. If you have a closer look, the stars show some fringes of all kinds of colors due to the movement of the air and the scope. But I expected this to be much worse. In fact, I am quite happy with the result and if you do not pixel peep this data, it looks really nice.

The new camera is mindblowing. Compared to the ASI183MM it is a huge step up in the right direction and it fits my 8" f/4 really well. Although there are now new problems to fix, I am really happy with my purchase.

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.
