It's pretty quiet!!! Does everyone have clear skies? I've been fogged in since Dec. 24th but finally got one clear night before it started to snow again. I...
That is a nice shot of M97. I have yet to image<br>that one...hopefully in the next few days. We<br>are in the clear for today but not tonight:<br>30+ mph wind...
Well it might be warm down here but the skies have not been clear. Here are a couple of peeks into the Milkyway. I intended to look at Eta Carinae with the...
Well, it has been snowing and cold here for<br>days. I am beginning to ask myself if there<br>really are stars up there! Maybe next week<br>will be better for...
Three new images taken on February 4, 2000.<br>It was a pretty good evening for seeing<br>even though a front was due through the area<br>later in the evening....
Hi John, good images (as we now expect from you). Your data on NGC3893 says 5/5sec exposures - obviously 5 mins, as you say in the message.<br>Glad the snow ...
It was clear the evening that the CFW8<br>filter wheel arrived at the house, so I<br>had to play. Here is the first image<br>taken RGB through the ST7 (non-E...
John and the group, I've been gone for a couple of weeks and I'm pleasantly surprised with the excellent images that have been posted lately. For a first RGB...
The issue about ratios is an interesting one.<br>When I got the filter wheel with the included<br>filters, they recommended in their manual<br>(yes...I read a...
John, yes. Colour adds a dimension which is very seductive. Guess I'll be going that way as soon as I get my permanent telescope pier set up. Colour filters...
Oh yeah I am addicted! ;-)<br><br>The saga and the infatuation continues. <br>Last night was clear and calm though lit<br>by the first quarter moon. I managed...
John-<br><br>Your images are wonderful! I love the Horsehead. <br>Also, your sketches are great. I got started on them and couldn't quit! You're right, Serena,...
Thanks Norrene, I have been bitten by the color<br>bug, so that is the route I will be going for<br>the next generation of images. Doing color<br>work is so ...
Hi John,<br>Can you tell us about the relative advantages of RGB versus CMY filters? The matter was raised on the Starlight message board and the response was ...
Hello everyone,<br><br>Yes - I saw the post on the SXpress board, but it<br>did not really get to the heart of the matter.<br>The issue of RGB vs. CMY is...
John, thanks for the thorough explanation. Of course you have raised the other thing I had at the back of my question: LRGB. So will you be saying that you ...
Hi Serena,<br><br>For color LRGB work one only needs the color data<br>to match the luminance data. The "brightness"<br>data is not required from the RGB data...
John and Serena,<br><br>I used True Technology RGB filters for many of the LRGB images on my web site. In fact, when I purchased the SBIG filter wheel I ...
Interesting. I like the SBIG's for their built-in<br>IR blocking as well: that is a real benefit. <br>Their clear filter allows for parfocal LRGB<br>imaging ...
John,<br><br>I managed to find my TT sheet and specs. are as follows. Red filter 610-720nm (SBIG 612-670), green filter 490-590 (SBIG 488-574) and blue filter...
Hi Cal, <br>Thanks for the details. Yep - we have clear skies<br>here tonight, but a big bright Moon will be<br>smothering the faint fuzzies I'm after. In...
I'm trying out a 4" f/5 refractor for those wide shots I couldn't get through my Schmidt-Cass and finally got a clear night to image M81. I think it's on the...
Thank you Serena for commenting on M81. I managed to get a shot of M106. Unfortunately, haze moved in during the color images and the light from town ...
Nice image there Cal. Who made the refractor?<br>Could you tell us the details on the scope:<br>lens system, etc. Just curious. I am <br>looking to get a wide ...
Well an interesting story this:<br>I was out imaging on the night of March 24-25<br>until about 10:30pm local. Sue, my spouse,<br>went into labor with our...
John,<br><br>First I'd like to congratulate you on your new baby girl. I have two girls myself. They like to pal around with me in the observatory which is ...
John,<br><br>First I'd like to congratulate you on your new baby girl. I have two girls myself. They like to pal around with me in the observatory which is ...
I took this image before the clouds rolled in last night. I hope I can get some RGB frames before I move on to another object. I'm amazed at the detail I can...
