Astrosurfing on this rainy nite tonite, I ran accross this apparently up and coming site and found some neat stuff such as 8/10" open newts with zambuto...
I have read 4.5nm narrow band filters may not work well with fast focal ratios. Can anyone tell me if the Custom Scientific 4.5nm Ha, OIII and SUII will work...
Keith, Assuming your scope has excellent color correction, then thickness dominates how parfocal your filter set is. On the average, I measure about 2 - 3...
Morning All! Likely another silly question from a new imager here. I have an SBIG STL-11000 camera with CLRGB & Ha filters from Custom Scientific. SBIG ...
We are pleased to announce that we have completed our speaker list and program schedule for the East Coast Conference on Astronomical Imaging, taking place on...
Dear fellow imaging enthusiasts: As you probably know, after the hugely successful AIC in California last November, a few imagers from Pennsylvania (Jim Misti,...
Perhaps the upcomming 2-4 day Imaging Conference in Suffern NY next week at the Northeast Astronomy Forum is a factor. Perhaps folks are opting for that...
Yea--lots of reasons, I guess. We went out on a limb--but even if it crashes and burns and we have to pull the plug, we can at least say we tried! Take care, ...
Hi Everyone, It is time for me to pick up some filters for my imaging setup. I am currently using an SBIG ST-2000 and a unmodified Canon Rebel XT-350 for ...
Brian, parfocal filters are not necessary, but sure make life easier. This is especially true if you do narrowband imaging and can focus on a green or clear...
Don, Please see body for questions and comments Brian ... H- ... Understood. The AstroDon filters are parafocal at f5 without issues. ... signal ... perhaps ...

After a long period of use, I have discovered that my Ha and my RGB set of filters are quite dirty. I tried in many ways to clean them, but stripes and halos...
Hi all, I have an LXD55 with Schmidt-Newton 10" + Orion 80ED. I autoguide so I can do 2 min exposure at 1000mm focal. I want to do faulse color images of...
Sorry, I forget to say that my Cameras are DSI-Pro and Toucam Pro B&W. Ludo France http://www.astrosurf.com/astro-jaugey LUDOVIC JAUGEY - J629922/users/PS A...
Hi Ludo, I'm not an expert, but most of the false colour pictures of Nebulae that I've seen have been H alpha/ O III or H alpha/ OIII / SII. I think that...
I have an SBIG ST2000ME (which only has about 25% QE at the Ha wavelength). I have the CFW-8 filter wheel with the standard SBIG LRGB filters. I am looking...
Did you mean the ST2000XM? That's the imager I use. I just started using the Astronomik 13nm Ha filter. I've tried several others but this one is the easiest...
... the ... I've taken a lot of images using 3nm custom scientific narrowband filters on the following scopes/lenses: FSQ106 (f/5) FCT76 with reducer (f/4.2...
Hi, I do have one small addition: Our latest Astronomik filters have 11,5nm FWHM instead of 13nm before. This offers you the same number of guiding stars and a...
Tried out a 12nm H-alpha filter at my home base and found it too wide for the light pollution I have. Awaiting a 6nm Astronomik filter that I expect will do a...
Thanks. What is the thickness of your filters? (From what you said I assume your 11.5nm Ha, your LRGB and your other narrow band filters are all the same,...
Hi, all of our filters have a thickness of 1mm. All filters of the CCD line are parfocal. (Upon request we can also supply parfocal filters for systems as fast...
Just caught this thread. Since I just started imaging with a new Epsilon 180 I've just begun to image with all 3 6 nm Astrodons in an STL11000 at f/2.8....
Keith, I just remembered that you mentioned already having CS 50 mm 4.5 nm OIII and SII for your STL11000. I've been told, but have not tested this myself,...
Don I am using the astrodon 6nm in my e180 too. Initial resuls are encouraging but I am still in the initial stages of deployment and have been sorting out...
