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...
We are excited about the upcoming ECCAI. All last minute details are coming together, and we are additionally pleased to announce that well over $4,000 in door...
Richard, the scope really does hold promise, but requires some work and patience, as we both found. First, one absolutely needs to attach an electronic...
Greetings, I recently bought a used ST8-XE and CFW8-A. Included in the deal was an Astronomik Ha filter with the markings "Astronomik Profi Ha CCD 000372". Is...
Hi there, I´ll be on a bike-trip across france for the coming three weeks. I will stop my membership of this group for this time. If anyone has a question ...
I recently obtained the Astrodon 6nm OIII and SII filters to accompany my Ha, which is also an Astrodon 6nm. The camera I use is a ST-2000XM. My first attempts...
Hi, Phil, I can tell you what people are doing with the ST2000XM big brother, the STL11000XM on longer focal length scopes like 12 - 20" RCs or SCTs. Our...
Hi All, I was out trying to take LRGB/Ha images last night. What happend is that in the blue and green chanels had LARGE reflections around them. What is the...
My mirror seems to be flopping around more than it used to. I'm worried that the retaining ring may be coming loose. I'd like to pull the primary but I forgot...
If you don't get a reply here, perhaps you can visit the SCT users group. I know I read through a great proceedure once, but I did not save it. The gent had...
Thanks but I found just what I needed on the C-11 Group (go figure! LOL). ... From: Kevin To: Astroimaging_filters@yahoogroups.com Sent: Monday, October 09,...
just discovered over the weekend and has been in a good number of images taken of IC1396 over the past few years, but apparently no one ever noticed it...

Thought I'd share "first light" with my very crude spectrograph; basicall a DSLR shooting into a shoebox with a slit at one end and a diffraction grating...
