Quote:I've seen the nebulosity without filters plenty of times.I've also tried filters. As often as not, especially with the O-III, the filter actually hurt the nebulosity, cutting it down to almost nothing. Not so much with the UHC, but I've only tried it once and it enhanced the nebulosity just a tad.

Quote:Can the nebulosity associated with the Pleaides be observed visually or is it only visible via AP? If it can be visually observed is the a particular filter that may help? I observe mostly under light polluted skies so I don't see it from here but I'd like to try from a real dark site.

I want to do more then just look.
Quote:Can the nebulosity associated with the Pleaides be observed visually
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
A man is a small thing, and the night is very large and full of wonders.
Quote:So if you think you see the nebula, check out the Hyades and other bright stars in the neighborhood, if they do not appear to look foggy, then I guess you have seen the nebula.

Quote:There are definitely many brighter areas which are not simply on the images (probably some groups of stars or just trick as one tends to put the bright patches around distinguished groups of stars). But some of the features seems to be real.
Quote:Quote:There are definitely many brighter areas which are not simply on the images (probably some groups of stars or just trick as one tends to put the bright patches around distinguished groups of stars). But some of the features seems to be real.Looking at that sketch, it seems that the Merope Nebula is unquestionably real. The others look to me like classic connect-the-bright-dots pseudo-nebulosity. The same illusion that caused Messier to see nebulosity in M40 and M73.
Quote:Then please explain to me why it is on nights of good transparency/seeing that this connect-the-bright-dots pseudo-nebulosity does not appear around other bright star groups like the Hyades.
