I observed the irregular galaxy IC2574 in Ursa Major the other night. Using 25x100 binoculars, I could glimpse only the northern part of this low surface...
I've had a few experiences over the years at big star parties that involve laptop light trespass and I'm wondering how to prevent it. Most recently, a fellow...
Howard; I changed the title of this thread. At some point, in some way, we need to get the word to people that blinded observers are not going to put up with...
Howard, I think I know the people you mentioned. When I walked by them on the spur road, I thought their laptop screen was way too bright because it was...
On the general topic of controlling stray-light emission from computers: As an enthusiastic software developer, I wrote a Macintosh program that in effect puts...
Has anyone tried to observe Gyulbudaghian's Nebula recently? I was at Cherry Springs State Park this weekend(8-30&31-08) and isolated PV Cep but was unable to...
James, I posted my negative result on Amastro one month ago. http://tech.groups.yahoo.com/group/amastro/message/21569 ...not seen in an 18-inch or a 25-inch...
As a enthusiastic visual only observer I have used my laptop track down 14th and 15th magnitude objects (visual, not blue magnitude). Maybe not 16th... but...
Thanks Steve, my new title somehow didn't stick with the email when I sent it, darn it. Anyway, I like the point Mel made about green lasers and how successful...
Tom, I do not really understand the physics of this object, but in my observation of PV Cep on Sunday I noticed a definate red color which Greg Crinklaw...
... Me too, Jeff. I can't see any of my keyboard. Sometimes when I have the screen brightness turned down too much, I find it unreadable. I also set my...
... I like what you say. And I can see how you'd say that 'most observers 'know'...' I have the same feeling too. Last survey I saw said that ~ 1/3 of star...
First off, the title for this email should be" And now a few words about the 2008 OSP..." Ok, I've gotten the laptop light trespass issue out of my system, so...
... The Markarian survey was done with a big objective-prism in front of a Maksutov (or Schmidt?) telescope. He looked for objects that were bright in the...

Hi Howard, However well meaning, you did the wrong thing.?NEVER complain to fellow Star Party attendees about the light they are giving off, or that they in...
As an Amastro moderator, I have the enviable task of monitoring each of these messages. I think the subject of laptop monitors at star parties is relevant...
IMHO, rubylith and Plexiglas aren't transparent enough. I don't mean that they don't let enough light through, but rather that they have a blurring effect....
Thanks Brian, that answers my question - it's the star like object, not the galaxy its inside of. Also good to know its now considered a BL Lacertae-type...
Sue, I have tried and agree with the Plexiglas "blurring". What I was very successful in doing was to sandwich a red light filtering material which is used in...
I just purchased red, 3 mm thickness plexiglass from Spheretec. I don't see any blurring at all and I can read the text well. I use it only for my scope drive...
This past weekend I had a negative observation using my 12.5" dob. Last year around this same time, I was able to detect it with this same scope. I also tried...
Hi ! I’ve tried it last night with my 22’’ at an observing site with a dark sky and under very good conditions … without success either. I wonder if...
I use 1/16" red transparent acrylic for my laptop. I got it from Sloan's Woodshop (Stock #997) (http://www.sloanswoodshop.com/acrylic%20sheets.htm) based on...
A likely nova has been reported independently by several amateurs. The position is close to: 17 57 32.9 -30 43 10 (J2000), and it is about mag 9. This is...

I saw a ever-so-slight brightening in the area of 2MASS-GC1 in Sagittarius last night with my 25" f/5 under a fairly dark (21.15 SQM). I had to rock the scope...
Kent, I know this globular has been in my field of view a number of times with my 20-inch and a friend's 24-inch, but I have yet to convince myself that I have...
