Hi fellow group members, I am finally posting one of my images, I have been waiting till I get one that I am especially pleased with. Imaged with an LX-90 and...
... Hi Iver, That's a really nice image of M51! There are a few unsharp-mask rings around some stars that you might want to clean up, but that's a very minor...
I decided to revisit imaging with my LX200. http://www.makos.darkhorizons.org/Astronomy/pages/m57a.htm Looks like the light pollution is getting worse, or...
Hi Paul, thanks for looking, I use a web cam for guiding that way I don't need to take darks! I'm eager to get that USB2+SXV guider,it's a chore to find a...
How is focusing going to be accomplished? The NexStar GPS11 has the Fastar option that allows you to remove the secondary mirror and replace it with a...
Do any of you folks have any experience taking film images with an SCT? I've been imaging with my TV101, but I would like a little more focal length. I've got...
In a message dated 7/10/2004 12:37:20 PM Pacific Daylight Time, ... I have tried imaging with my C9.25 (fl=2450mm). It is F10. I think it is just too darn...
Hi Richard. Try the 11 with the focal reducer, at least one time. The 11 has a much bigger primary baffle. The RC is still the same size but you might get ...

I used an 8" f6 newt for a bit. What a pain. Collimation has to be SPOT ON for any decent images. I managed to get some images out of it, but consistency was...

I've used both. Check out: http://www.santangeli.net/lxd55.htm for an older page on using a 10" LXD55. I just picked up an 8 inch too that I actually plan on...
An aside... I've pretty much decided that my next project is going to be an ultra lightweight 16" F4 newtonian to put on top of my AP900 for imaging. It will...
Hi All, Thought we should move this discussion off TAC. I put together a web page with some photos of the camera dissection to remove the filter, and a couple...

OK, this makes me wonder how it now performs at night as an IR "picture taker". Not in a telescope but as a "see in the dark" kind of thing.??? ... Phil...
Hi Phil, Is dark current a significant problem with this camera? I thought that Canon somehow managed to lower the noise level to a very low level allowing...
In a message dated 7/13/2004 4:28:09 PM Pacific Daylight Time, ... PC, I'll try the same shot after dark tonight. Although the is a street light in the...
Get a person in the picture -- that should be very interesting :) Thanks for posting the pics, Phil! Paul ... From: pterzian@... [mailto:pterzian@...] ...
Didn't Sony initially have a problem with their IR night-shot stuff apparently seeing through peoples Clothing? I'm not suggesting an experiment or anything......
Make sure a "warm body" is in the picture. Dog, person, etc. That is the real test.. Whether it can see in the dark better than "you" can. Cooling the...
Heh, heh... That was the videocams. Certain kinds of material were transparent to it. When the material was wet it was even better. In later models they...
I have been experimenting with dry ice cooling to improve the dark current noise of the Canon Rebel sensor. This idea uses a stainless steel sprayer with some...
That is pretty interesting. I assume that you just let the cold CO2 spray against the chip. It evaps and no wetness, very very neat. ... Phil Chambers...
I decided to revisit M17 using my HX916 http://www.makos.darkhorizons.org/Astronomy/pages/m17.htm Click on the image for full size. Cheers !! --Ivor...
