m1

This image of M1, the crab nebula, was taken, in December 2007, from weymouth, Dorset, using an Orion Optics DX250 Newtonian reflector fitted with a SX MX5C one-shot colour ccd camera. It is the result of adding the best 90 x 60 second unguided exposures, taken over a number of imaging sessions. Image acquisition was achieved using AstroArt 3, which was also used for telescope control. Colour synthesis was performed on the individual images and a master L frame extracted from the resultant summed colour image. This master L frame was then background subtracted using the 'level' control in AA3 and slightly sharpened using a couple of cycles of Maximum Entropy deconvolution. An LRGB synthesis was then performed using a gaussian blurred master RGB frame. The image was then exported into PixInsight LE for curves and levels manipulation and gradient removal using 'Dynamic Background Extraction' mode. The image was saved as a Tiff file and finally exported into NEAT for slight further noise reduction and saving as a low-loss jpg file.

Any comments or advice greatly appreciated as usual.

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.
