I'm putting way too much time into this project. But, hey, I'm having fun. :) I got more shots of Pluto tonight and have now posted two versions. First, two images of Pluto taken last night one hour apart: http://users.wirelessbeehive.com/~paw/temp/hour.jpg Second, two images, one taken last night and the one on the right taken tonight: http://users.wirelessbeehive.com/~paw/temp/day.jpg All images are screen saves of raw (unreduced) FIT files. I found that if I reduce the images Pluto becomes too faint to see. I'm thinking I'm going to try this again but with much longer exposures so I can reduce them but still have Pluto visible. Now a question for those using Chuck's cross-eye technique to view these pairs. When you view them do you see a single dot or two dots floating above the background field of stars? I see a single dot for the 1 hour pair but 2 when I look at the 1 day pair. And now with dawn approaching it's off to bed. Hopefully my eyes will uncross by the time I get up this afternoon. :) Carpe Noctem! patrick On 13 Jul 2010, at 09:27, Dunn, David wrote:
Thanks for posting this. I am able to see the dark nebula and the star that was near it when I saw it off to the upper left.
Thanks. Dave

Hi Dave,
Your thread about Pluto prompted me to shoot a few images of Pluto tonight.
Here are two shot's taken 1 hour apart. Pluto does move between the the two shots but not very much. I did not mark Pluto's position in case some folks want to try to find it by using Chucks "cross eyed" method (that method worked for me but then I knew where to look).

But I've also posted an annotated image:

All images are shot with the C-14 operating at f/5.5 and ST-10 binned 2x2 and chilled to -10. Clear filter. 15 second exposure.

Did anyone else take a look a Pluto last week? Sky and Tel had an article about it crossing in front of a dark nebula last week. I was up at Monte Cristo so I took a look at it through several telescopes. On Wednesday night I saw it through both my 16" at 156X and through Ron Vanderhule's 25". In my 16" it was barely there. It was not far from a 14.5 mag star. Using averted vision I was barely able to see them. Through Ron's 25" they were bright and easy to see. Pluto was slightly brighter than the star. I thought it was neat to see Pluto without needing to take or draw a picture and then look again a day later. I also took at look at it on Thursday night through OAS's BOB (18.5"). Pluto had moved to where the star was.
