No, I actually didn't look for them. But web pages often tend to get updated with delays. Ask Alpine, if they already have gotten some of then from Baader. If...

Nice results and a great story Marco. That sensor you have is working very well. Too bad that the humidity got you. That's a big sensor very close to the...
Details available here: http://www.astronomik.com/english/enghome.html I paid 260 Euros for mine for a certified >90% transmission at Ha. Here is an...
hello all, I wonder if someone could do a simple photo test for me. Use a simple point and shoot type of digital camera, take a picture of the horizon, be...
Just looking to see what people are using for astroimaging? I have a meade DSI camera and color camera, but was thinking about getting into this end of the...
Hi, Orion is now offering a new Skyglow filter as an imaging filter. They are still offering their regular Skyglow. I suspect that the higher cost imaging...

Hi, I ordered and received a Baader 35nm bandpass Ha filter. While most are interested in narrowband Ha filters, my interest in this filter was to be used as a...
You got what you have payed for: http://www.baader-planetarium.de/zubehoer/okularseitiges_zubeh/farbfilter.htm#halpha-ccd There is nowhere a claim by Baader...
I am a little mystified at what your gripe is with Baader. You order a 35nm filter on the strength of the curve of a 45nm filter, and you are surprised that...
Then complain at Alpine that they (and not Baader) linked the 35 nm Halpha filter entry: http://www.alpineastro.com/filters/filters.htm#H-Alpha to a probably...

Hi John, I saw the 45nm on the Alpine chart, but thought it a typo at the time of order. In any event, the group now has an independent transmission...
Yes, I saw the earlier post, the smudged one should clean up fine. I have the 7nm Baader Ha and it does a fantastic job.Good luck anyway.John H. [Non-text...
Hi Richard C, yeah, it may be the water. More likely the scotch, vbg. If my testing just brings complaints, I can solve that quickly. If needed I now have a...

Hi Samir, very nice. How do you calibrate your spectrometer to know the exact bandpass center spectral line and width? Is there anyway you can determine the...
Hi, I just received the older version of the Baader 45nm bandpass Ha filter and transmission tested it. Unfortunately for my application it is still skewed to...
Ha is easy. I just take a spectrogram of the Sun. It has a prominent notch at Ha, so there cannot be much quibbling. I get the Angstroms/pixel from the rest of...
