Here's an article on imaging using a strobe wheel with the important point that real science is being done. You'll read that variations in the pulsar's output...
... If you used an [OIII] filter, then you were imagining the Loop, since there is no [OIII] emission in the nebula. You might have used a UHC-type filter...

... I have only successfully used the H-Beta and UHC filters to see Barnard's Loop with the unaided eye. It is invisible with the OIII filter. With the...

Howdy all; My notes are similar to David Knisely. It was never easy, but I could pick it out. I did not try the Deep Sky filter on it, because I did not have...
Thanks for the replies. Several friends of mine saw The California Nebula naked-eye at The East Coast Star Party in Coinjock NC two weekends ago, an easier...
Hello Group, I'm lucky enough to be one of 16 folks who will be using the 82" @ McDonald in Texas the nights of Nov 17th & 18th. I have compiled a list of...
... You think so? For me, BL is less difficult, though I'll admit that as I learn to see the CN, it becomes quicker to pick up each try. Mel Bartels...
Waiting and hoping this dreadfully overcast sky clears off in time for the transit tomorrow afternoon. At the moment 1.5 out of 3 forecasts seem semi- hopeful,...
Hi Kent, I used two 2-inch H-beta Filters to see Barnard´s Loop several times in the alps (fst 7m,0 to 7m,3) with both eyes. It works also with only one eye....
Hi Paul, I wonder if the brightest PN in the Andromeda galaxy would be visible in the 82" by blinking with an O-III filter? Kent ... From: "Paul Alsing"...

Hi Paul, I've got a few ideas for you: - Resolve G1 and G2 globulars of M31. - The central star of Abell 70 - magnitude 19.1 - and can you see a color...

Hi Paul, I know it is bright and boring but think about M77 in Cetus too.It is a relatively small (about 6' diameter) very bright galaxy with a Seyfert II...
Paul If the Davis Mountains were a few thousand miles higher I would suggest the Homunculus, but if you are up late enough you could try counting the stars in...
Hi Paul, I'd attempt to observe the twin cores of NGC 6240 (see http://www.skyhound.com/sh/archive/jun/NGC_6240.html). Clear skies, Greg -- Greg Crinklaw ...

Oops, I misremembered the right time of your for NGC 6240. Here are some other ideas: Look for fuzz surrounding CW Leo NGC 1535 has remarkable detail in my...
I will second the choice of NGC 1535. Although it was 21 years ago that I last observed visually this planetary nebula, the memory of that observation remains...
I strongly recommend NGC 1514 in Taurus. This is spectacular with an O-III filter in a big scope (it was in the 60" on Mt. Wilson), and it has an amazing...
Howdy all; Here is my observation of NGC 1535 with the Yard Scope. Because it is an alt-az scope, I can't determine the actual PA of the very faint star I...

... Interesting observation, Steve. I've not read of the pink colour in 1535 before. It's a bit surprising though because the [O III] emission in this PN is...

Observed Alessi 22 and Averi-Hunter 1 last night with my 12" Dob. Found using DSS image. Can't find out anything on these. Only place they show up is the...
