Here from a week or so ago is globular cluster M3 in Canes Venaciti. Taken with the Atik One through the Equinox 80, this is from 15 x 5min luminance frames and 12 x 2min each of R, G and B, binned 2×2. The faint fuzzy at the right of the image is mag 13 spiral galaxy NGC5263.
Last night was the first opportunity I’ve had for a while of getting into the observatory, and it was a real pleasure to do so! Shown below is an image of bright globular cluster M3, situated in southern Canes Venatici, though not too far from from Arcturus. Taken with the Atik 460ex OSC though the MN190, it’s comprised of 15 x 3 min exposures. No flat or dark frames were used.
Another quick test of the polar alignment; I managed to capture 5 x 5min R, G and B frames with the Atik through the MN190 before the fog built up and obliterated the stars – I’ll collect some luminance frames later. Still it’s not too shabby!
23 x 5min luminance frames through a CLS filter taken and combined with the colour frames:
I started from scratch on Thursday evening with M3, trying to make sure I had decent flats and darks, and then did a series of LRGB exposures. This picture used 20 x 2min luminance frames, and 20 x 1min each of R G and B, binned 2×2. The frames were then processed and put together in ImagesPlus.
I’ve been promising myself I’d do it for ages, and have now finally done it – bought a “proper” CCD for taking pictures. I now have an Atik 314L+, and last night had the first opportunity of trying it out. These pictures are both simply monochrome images taken without a filter through the ED80, but I do have the filter wheel and LRGB filters, along with a hydrogen alpha filter to try out once I get the power supplies sorted out!
