M83, a work in progress
Well the weather gods must have been smiling; finally clear skies so out came the astrophotography gear for my second attempted at M83. This image is an improvement on my last. Autoguiding work a lot better this time around using the ST-7/ED80 combination, focus was much better as well on the SCT. Dark frame and Flat frames were also taken for post-processing of images. I was not happy with the flat frame as it was more or les done by shining a light on the shed wall and taking an image. The finally result was an uneven flat frame which I think is evident in the final image.
Finally about the image: 8 x 5 minute exposure @ 800ASA with DSLR Focus, autoguide with ST-7. Dark and flat frame subtract and aligned with MaxDSLR. Cropped and processing with Photoshop. Reduce by 20% and converted to JPEG for uploading
