#43 - Friday, June 17, 2016

I should have known better than to go out when the moon was up and bright.  But alas, I went out anyway.  I had the bug.  I tried a few objects, but all were too dim to see behind the bright white light of the moon.  I imaged M101, but it came out rather dim and the background light was terrible.  I also imaged M81, but those came out terrible too.  I tried for a few others, but couldn’t really find them.  I also tried for the Blinking Planetary Nebula, which was quite bright, but too bright, actually, to see any of its detail.

14x30s, ISO-3200, no flat

It was so bright, in fact, that the image above was exactly how it came out of DSS – usually, those are too dark to see the actual object (that’s why the background is so dark).  I didn’t look at this one visually – I should have.  Next time.

I also tried to image some planets as a consolation prize (I was able to stay out late because it was a Friday night, and I stayed out till like 2 AM), but the C11 is terrible at planets, its aperture is too big.  Maybe I should get like an off-axis small aperture for it to decrease the amount of area for badly-bent light rays to enter, to put it in layman’s terms.  I couldn’t even really get them to focus in the eyepiece (the seeing was also probably bad).
