Last night I was looking at the Orion planetary J 320 with my 10" in a suburban sky and am a bit confused. There seems to be an involved star, and I don't...
Hi Kent, I have a color image of J 320 that I pulled off the internet years ago and it shows a bright knot near the edge of the main disk of this PN. If the...

Jonckheere (the 'J' of the J 320 name) was a double-star observer, and picked this up as a nebulous double star. It is simply a bi-lobed planetary with a...

That link appears to be "dead" but the link below link will probably supply anything you ever wanted to know about J320 ...
Hi Folks It could be argued that the Burnham's Celestial Handbook series is the most frequently consulted English language field guide available. As valuable...
Hoo-boy, Dave! That is EXACTLY the question I posed on the Cloudy Nights forum a few months back. You see, I too thought it would be a great project to...
Well, there probably is the need, but the undertaking would be enormous and very time consuming. If I were to do something like this, I would have to allocate...

There is of course the Night Sky Observers Guide. Any sign of volume 3 yet ? Tony Buckley [Non-text portions of this message have been removed]...
I presume that what David Riddle is talking about is _not_ 'Night Sky Observer's Guide', or Luginbuhl & Skiff, Hartung, Lorenzin, et al, but something really...

Tony; I was the speaker at the astronomy club in Sierra Vista, Arizona last month. I sat next to Bob Kepple and he said that version 3, the southern sky, will ...
What might be interesting is a poll here on who actually still uses Burnhams. I know I have it but have not looked at it for years as it is so dated. I think...
Regarding the poll of who still refers to Burnham's Celestial Handbook I'll have to say the books have collected cob webs on my bookshelf for years. I rarely,...
... This very question has been asked many times in different forums. I think Brian Skiff has at one time considered the task of updating Burnham, but...
... I used it a few months ago for actual observing information; I use it every couple of months for reference/historical information. -- Brian Tung...
Greetings: Maybe what is not needed is an updating/revision of Burnham's, but something in the spirit of the three volumes. Sure, Burnham's has a lot of...
The problem is that many objects could easily fill a separate book, and some (Crab Nebula, Orion Nebula and Sirius) already have their own volume. Leo "Sure,...

... Precessing the 1950 coordinates to 2000.0 is easy, once someone's done the data entry. And that's likely to be good enough except perhaps for Proxima...

Hello all; For well over a decade I observed the objects from Burnham's and three years ago completed observing all the deep sky objects north of -40 degrees ...
Amateur Astronomy Mailing ListIn regards to Night Sky Observers Guide Vol 3. I was sent a pre release copy to read and remark on and for those of us inte...
Thank you, Fred. You said it better than I did! I didn't mean to suggest a literal rewriting of the classic series. However, there seems to be a call for a...
I have not used my Burnham's for several years. I used to use it a lot up until about 15 or so years ago. Now I do most of my planning using the internet or...
... and ... For the charm, love, and enthusiasm, I would keep all of Burnham's original text. Updates would be in the form of factual correction (for example,...
I have been reading a lot about dark adaptation and doing so, dark adaptation curves for rods and cones. I am especially interested in the rods. I have only...
Jan, I don't know if this has been investigated (it probably has), but I suspect the "differential adaptation" from steady-state at say 22 mag/arcsec^2 to 27...
Why in the world would one wish to tramper with (and likely detract seriously from) a period classic? Would you wish to do the same for the works of Webb,...
