M83.
Hi,
M83 was the first galaxy I imaged last year with my new setup.
Time to revisit, this image is just over 2.5 hours. I couldn't see any advantage in any more exposures, using an unmodded DSLR and the resolution if the 8" f/4 astrograph.
The stars are not as I would like, because some silly bugger left the mirror fan going and there's some flexure too. Having said that, the overall image is fairly clean.
Equipment.
8" Newtonian astrograph f/4. on Heq pro 5 mount. Orion mini guider.
Unmodded canon 1100D, baader coma corrector, cooler box.
19 x 8 minute subs, darks and flat frames applied.
Median stack in DSS, processed in PS7.
Cheers,
Justin.
