PN ngc246, Galaxies ngc1232 & ngc1365
Hello,
We’ve enjoyed a couple of clear nights with good seeing recently and I had the opportunity to use the C9.25 and ST7 to image a few DSO’s; Planetary Nebula NGC246 in Cetus, Galaxy NGC1232 in Eridanus and Galaxy NGC1365 in Fornax. The images were self guided using the dual chip of the ST7 (TC211). I had problems finding bright guide stars for the self guiding chip, so was only able to capture Luminance data – RGB filters would have swamped the faint guide stars.
The last quarter Moon was a bit of a challenge, but the relatively small size of the ST7 chip (756x510) meant that gradients weren’t a real issue.
C9.25 with F6.3 Reducer/Corrector.
NGC246. 10x5 minute subs.
NGC1232. 8x15 minute subs.
NGC1356. 6x10 minute subs.
ST7E CCD camera.
Thanks for looking.
Cheers
Dennis
