Hello People, I just found this group whilst googling filters, so I hope you don't mind if I pop in and ask some questions? I shoot film through a Meade SCT...
Have have seen some very nice images done through higher transmition color filters on hypered tech pan and put together in a similar fashion to ccd images, and...
I have noted in other forums folks posting web cam images enhanced with IR pass filtering. I was curious first, how the filter does this. By reducing seeing ...
Hi, Kevin, I now make the Schuler filters and the IR72 filter would be ideal for getting the detail for Mars and then using the RGB from a webcam to colorize...
Hi Kevin... The IR filter you described will work fine on Mars (Jupiter is relly great in the IR). Only caution is that you will need to keep your exposures...
Thanks guys, I suppose I now have a use for this filter. I actually wouldn't use it with a web cam at least at first but rather an ST7XME. I needed a way to...
Kevin, Brian brings up a great point. The additional contrast you get with the NIR filter for Jupiter is due to methane, which occurs between 800 and 900 nm....
... order. ... back ... Astronomik's ... Kevin, I recently purchased an Astronomik Filter Holder and one each of the 1.25" and 2" drawers. I am very pleased...
Hi Don... The near IR stuff we can use with the sensors available on the amateur market pass a lot of interesting stuff in the 800-100nm range. Most of the...
I am going to try using Don's I series LRGB filters and a Baader IRPass filter on Mars, and want to increase the focal length of my system from its native...
I have now read that the TV powermates don't exhibit much in the way of amplification change when using different spacing. Unless others have contrary...
I seem to recall that TV publishes magnification vs spacing charts for their Barlows and Powermates. Perhaps you can check their website. Nevertheless that's...
Mark: You can see the spacing at this site. http://www.televue.com/engine/page.asp?ID=42- Regards, Eric. (México) -- In Astroimaging_filters@yahoogroups.com,...
it's that time of year again: the Fisherman's Wharf area in San Francisco has the Dungeness harvest beginning and in the wee hours of the morning we see the...
I have a basic question about imaging with filters and creating a color image. When using rgb filters, and combining them in Photoshop, the image comes out...
It looks unnatural as it is. The reason it looks that way, is that the you are arbitrarily assigning those very narrow wavelengths as red,green,blue, so the...
I think you actually have a good understanding of it by what you said. Now I'm going to ramble on like I always do. Feel free to stop reading :) You're not...
Hi all, I would like to send you my latest image of mars. Our new Astronomik Pro Planet IR 742 was used for this image. CS Gerd [Non-text portions of this...
Hi all, after some processing I´m happy to show the image from the posting before now in a color version: The attached image is a LRGB. The L part has imaged ...

Below is a link to an image of Mars at around 2am CDT (7 UT) this morning, October 29. The yellow dust storm everyone is talking about has just rotated into...
Hi Mark, Great image. I see you are using a manual Atik Filterwheel. Does manually rotate the Filterwheel mean a significant force ? due to the stops it has or...
Hi Rainer, thanks for the comment. The Atik wheel moves relatively smoothly once you get a bit of practice with it. It has a plastic or nylon bearing that the...
Great image and work with the IR Pass. I have yet to get out and give mine a whirl. I was worried it would be to much of a light reduction for any smaller...

Hi: In the 1014 message (former one), I posted a mosaic of Mars images, most of them including the last 2 taken with the Baader IR/pass filter. The other color...
