I checked my reference and it looks like I was wrong about C/1911 N1 since it was bright in August 1911 (about mag 4). By the time the other 3 comets had come...
Wow! The encounter of 1941 could be unique! A photo of this would be rare from the south, but hope someone comes forward with it (if there is one). Neal...

Brian, I can find scarcely any info about Comet Cunningham once it entered the southern hemisphere. I do know that Bobone (Cordoba Observatory) located the...
Hi Larry and Dave and the rest, Thank's for answering my question. ... I guessed it was a well known feature. I've heard a lot about "dark lanes" in these...
Another well known example of a globular showing dark lanes is M92. I have seen these lanes quite a few times in telescopes ranging in size from 6" to 18". As...

These features might be dark nebulae _in front of_ star clusters and thus not directly involved with them. Since the background is so bright it is easy to...
There have been many times during the recent century when two comets have been visible naked eye during _almost_ the same period. These were C/1995 O1...
Timo, Thanks for the correction :) One way to find out if these dark lanes are foreground objects is to have a look at the spectral type of stars close to the...
Hi Dave! I remember this rare event well. I was about to hike the Inca trail in Peru when I trained my optics on Hale-Bopp, 22P/Kopff and the star cluster...
Hi everyone, I remember a few years back at TSP some of us had the chance to observe with the 82" Otto Struve scope at McDonald. One of the objects we looked...

I'm interested in visual observations of the central jet of M87. A google search turns up Jane Houston Jones' account of seeing it well through the 60 inch...
I was able to observe the jet in M87 in a 16-inch SCT from my high-desert Arizona site a few years ago. It's a fairly bright object, but of extremely low...

... The dark patches these guys found have _maximum_ size of ~15" only, and the total absorption is only ~0.5 mag. I'd bet these are not visual objects, and...
