Baader FFC info?
I have been considering purchasing this unit for some time. However, the
pricetag seems a little high and I have some questions maybe someone can help address: Is the size of the FFC 2" or 1.25"? Do separate tubes have to be purchased to get each range of magnification, or are they included? Where is an on-line review available? What firms in the US have it at a good price? Thanks in advance, Rod |

The outer barrel fits into a 2" drawtube. It also has a female T2 thread (M42x0.75mm) at the telescope end. The camera side is T2 male. It might be necessary to screw it onto a 2" pushfit - T2 adapter for some magnification ranges, and directly insert it into the 2" focuser for others; where exactly it needs to be placed relative to the telescope's focal plane depends on the desired magnification ratio. See Baader's FFC usage diagrams he http://www.baader-planetarium.de/dow...ik.htm#english Do separate tubes have to be purchased to get each range of magnification, or are they included? You need to get additional tubes, but T2 extension tubes are "5$ a dozen", regular Ebay offers. Larger photographic shops used to stock these as well but all that trade has now gone to the net ... You can also use a T2-1.25" eyepiece adapter and then just use 1.25" extension tubes. No problem with that, except mechanical stability. Also, talk the vendor into making you a "good offer" Where is an on-line review available? I don't know. I'd also like to see a side-by-side comparison of the FFC, the TV PowerMate 5x and high-quality eyepiece projection. I'm not aware anyone has yet tried to do this. What firms in the US have it at a good price? Baader Accessories sell in the US via Company7, Astrophysics or buytelescopes.com. Their prices are usually quite close to the exchange rate, Baader sells at 598 EUR (includes 16% tax) so the US price will be between 600-700 USD. You might want to call Baader directly for a quote; They also sometimes offer "grade 2" (blemished, with slight coating irregularities, barrel scratches or a tiny bubble in the outer quarters) FFCs at somewhat discounted prices; if you happen to be in Germany in May next year visit the ATT astronomy trade fair in Essen, and be picky; it'd save you around 20%. No, it's not yet enough to pay for the flights Bye, FrankH. Thanks in advance, Rod |
