NGC 7023

Here is the 'Iris' Nebula imaged in 2006 using my MX5C camera.

I managed to get a couple of hours observing in and decided to image ngc 7023, a bright nebula in Cepheus, known as the 'Iris nebula'. This nebula is big, 18' x 18', has a magnitude of 7.0 and a surface brightness of 10.3, so it's reasonably visible through the eyepiece. It's also near, only 1.3kLy away.

My image consists of 45 x 60 second unguided exposures acquired and processed in AstroArt 3, taken through my 10" Newtonian / MX5-C combination.

Because it's big and only just fits on my ccd chip I took batches of 5 exposures at a time, adjusting the image for any drift in between and then processed each batch before coregistering the resultant 9 images to form the final image. This method may have slightly degraded the sharpness of the final product but it did mean I didn't have to worry about the image drifting around too much. Maybe I should just move on to autoguiding - or get a bigger camera!

There was noticeably less light gradients to cope with when imaging overhead, though.

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.
