About this image

The best shot of M42, the Orion Nebula, that I've managed to get to date. Taken with a Canon 250D through a NexStar 6SE scope (150mm SCT, fl 1500mm, f/10). I stacked 19 images with DSS and processed with PS Elements. My telescope is on an alt-az mount, which is tricky for long exposure astrophotography. I took about double the number of images but had to reject a lot that were not tracked properly, showing elongated or distorted stars etc. Also, to minimise tracking issues I had to take short exposures at high ISO. This has resulted in a noisier image than I'd like. I'm pleased with the way it turned out though.
