Telescope: Skywatcher 8" f/5
Newtonian, stopped down with an off-axis mask
Focus: Prime focus with 2x Barlow
Camera: SAC7B, uncooled
Exposure: 166 AVI frames used
Date: 27th July 2003 (local time -
UT noted on image)
Processing: Acquired in K3CCDTools.
Aligned and stacked in Registax (resampled 4x). Exported as FITS and
wavelet processing done in Iris. Exported to Photoshop as RAW.
Final image is GRGB, ie the Green image is used as luminance as it had the
highest resolution. Resized to 0.5 for final image.
Seeing was quite good but with
intermittent cloud. My mirror and Barlow are probably not good enough
to give a higher resolution image.
