Last night was the first moon-free chance I’ve had for a while to use the Atik 460ex, so I turned it on to M1, the Crab Nebula. Taken through the MN190, this image is comprised of 18 x 3min exposures, and processed in ImagesPlus 5.0. I’d have liked more photons, but a very uncooperative bank of cloud rolled in and cut the session short! I used a CLS filter because of the light pollution I have, but I need to experiment shooting without the filter to see if I can get better colour balance and saturation.
An image of M1, the Crab Nebula, taken with the Atik 314L+ with LRGB filters through the MN190. This was put together using 12 x 5 min luminance exposures (CLS filter) and 12 x 1 min, binned 2 x 2, for R, G and B. I was quite pleasantly surprised by the amount of colour in the stars I picked up, so decided to turn it from science into art by pushing the saturation way too high. It’s quite pretty though 🙂
Both images were taken through the LX200R without focal reducer using my Canon 400D with CLS filter. In both cases, dark, flat and bias frames were used to calibrate the light frames in Images Plus.
First up is M38, a large, bright open cluster in Auriga. This is a stack of 25 x 3min frames at ISO 800, and although I seem to have lost colour in the stars, the background light pollution gradient that I’ve been plagued with recently is conspicuously absent. Focus was also slightly off, which makes the stars seem slightly more bloated than they should be.
