I always have a story to tell! I very rarely use the Nikon D800 for astrophotography, but I have been waiting for an opportunity to image this galaxy with it, because I really liked the idea of a widefield view. After all, with my other cameras it tends to fill the frame. Anyway, I set out to take 60 subs of it at 6 minutes long each, but alas the wireless timer failed [as per normal - it does not like this camera, so I have ordered a different one], and so I actually got only 30 subs. Also, the vast majority of them were in my worst light polluted zone, and so bad was it that pretty much 20 subs of the object were almost 'whited-out'. When I stacked them the laptop crashed - they are massive files - but it worked the second time round. Then the stack had such a bad gradient from the light pollution I feared it was impossible to process this, even with DBE in PixInsight. But, after some effort, I am pleased I have got what I did. I really like the full frame Nikon and it holds the colour of the stars well, even the larger ones - far more than my Canon 700Da. If only I had a modified version of the D800 too! I may try imaging this again when it moves into a better area of the sky - but I took my opportunity on Monday because I knew the weather was closing in. Needless to write, I used my 3" refractor for this - my Skywatcher ED 80. 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.
