Hello all: Would you give me some summer observing ideas to post on the website besides the perseids in August? Thanks much all Kathleen McCarthy Warner SLAS webmaster
The summer Milky Way offers some great opportunities for tracking down the best of Barnard's "dark nebulae". You need a fairly dark sky, but Barnard discovered them visually with a 6" scope, IIRC. We saw some in 70mm binoculars at Binopalooza. Thanks to Dave Bennett for pointing this out. Chuck --- "Warner, Kathleen" <kwarner@acs.utah.edu> wrote:

My all time favorite summer object is M17, the Swan Nebula. It is especially nice in large aperture and with a UHC filter. Three less looked at objects include the Bug Nebula, NGC6302, the Blinking Planetary, NGC6826, and the Cat's Eye Nebula, NGC 6543. These are very nice planetaries. The Blinking Planetary will appear to flash as you look at and then away from the central star. Don't forget Kim Hyatt's Fairy Ring cluster at 20 hours 4 minutes and +38 degrees 20 minutes.

Brent, have you noticed that the "blinking" effect seems to lessen with increased aperture?
From my experience, the effect is most pronounced with 6-to-12 inches of aperture. Above that, the effect begins to dimminish.
I'd like to add that, with proper filters, planetaries in general are excellent targets for observers in light-polluted locations. The year our daughter was born found me at home virtually every night, yet that summer I managed to detect over 100 planetary nebula from my West Valley home, using a 10-inch Newt and LPR filters.

Chuck (and anyone else), Do you have an LPR filter that you prefer? dave Chuck Hards wrote:

I use three currently: Lumicon broadband (2") Celestron narrowband (1.25") Orion broadband (1.25") Lumcion OIII would probably be best for planetaries, however; the broadband works sufficiently well for ID purposes, especially on those "tiny blue dot" types. I'm not especially attached to any particular filter, and due to their relatively high price, I bought mine used. Chuck __________________________________________________ Do You Yahoo!?

Chuck, I have not noticed that effect. I have seen the blinking phenom in 8-22 inch scopes. I have noticed that once I knew why it blinked, it didn't blink as much. David, I use the Limicon oIII and the Lumicon UHC the most, but I also enjoy the Del Woods filter I got a long time ago. Brent --- Chuck Hards <chuckhards@yahoo.com> wrote:
