NGC 5873


Step 1

Move mouse over sketch to simulate sliding in the OIII filter.

Observation Notes:

I got my first look at this diminutive planetary nebula through Eric Graff's 6" f/6 reflector. He was using a filter slider with an OIII filter in one slot. By sliding the filter in and out, it was possible to see which "star" was actually the nebula. He let me borrow the filter and slider so I could make a sketch at my scope. The star at the center of the sketch (also noted by hash marks) is the planetary nebula. Moving your mouse over the sketch will simulate the blinking effect. It looked like the nebula may have exhibited some dimension, but the seeing wasn't the greatest, so I couldn't be sure.

Wohoo! You did it! That is an awesome animation, my friend; it captures the view just perfectly. I've been itching to get my scope out under the stars but other obligations and finicky weather have kept me away. *grumbles*

Thanks for the update!


P.S. "breezy"? Hah!

Howdy Eric,

Any excuse for a rollover graphic, eh? =)

"other obligations" and "finicky weather" have been the name of the game over here too. I've decided to start making more observations outside my front door to help scratch the observing itch more often. Not that I'll be searching for the tough little boogers you go after from my front yard...

And yeah...maybe Fujita Category 3 would better describe conditions, but the winds by 1 AM were a smidge better than the Cat 5 gusts we had earlier in the evening =)
