Quote:I just got the STT-8300M and self-guiding filter wheel FW8-STT. I opted to go for Astrodon filters. imho they are higher quality than the Baader filters.

Quote:Quote:STT-8300M with integrated OAGThanks Jerry; to confirm, you mean self-guided filter wheel with Baader filters, correct? Also if you can elaborate what issues you encountered with it and how you fixed them. Technical details will be appreciated. Regards
Quote:I have looked at the Astrodon filters, which for what I can see are more narrow than these narrow bands. They are also more expensive, and they require longer exposures.
Quote:I am not sure what all the problems were with the original filter wheel, but it was swapped out and the firmware update several times and now it works flawlessly.

Quote:I would like to add one more comment about the STT-8300 self guiding filter wheel. If you'r telescope is not 100% collimated, you will have serious problems finding a guide star. Mine was MOSTLY collimated but a bit off and I kept on having difficulty finding guide stars. After very accuaratly collimating using CCD Inspector. I now find it much easier to find guide stars.
Quote:OK. Here goes... the face plate tha contains self guiding filter wheel has an STL thread. If your APO Refractor field flatner has a built in t-thread like my TV60is, then you have a problem. You need to fabricate a special adapter to step down from STL to T thread size.But since your focuser accepts 2" nose piece, then you have nothing to worry about, everything you need is included in the box. Also. In the future you might want to make a customer adapter to thread directly onto your focuser for a more secure connection. How that is done depends on the focuser you have. mmalik, I'm abroad now. Traveling back home tomorrow. If I remember, I will provide you with pictures.Jerry, I have the most horrible skies you can imagine for this hobby but I'm so stubborn and just keep on at it. Also, I too had filter wheel problems initially in the form of filter wheel failed to initialize errors. But after a couple of firmware updates, the errors have mostly gone away. I still get the occasional error when I first try to connect to the camera, that usually happens if I try to connect while the camera is still initializing. Its best to wait a bit after powering on the camera till all the filter wheel movement stops then connect in software.
