Well I have owned two TV-85's so very familiar with the scope(check out my review on my blog).

Nice video! I am new to this and I really like the idea of getting a refractor for super high-quality visual astronomy. The argument on all these forums seems to be the bigger aperture equals better viewing. If I can purchase 120 mm refractor, can I not then just use a 2x Barlow lens to get the focal length needed for some deep space viewing? I am trying to accomplish getting one telescope that does it all. Any advice would be greatly appreciated. Cheers, Phil P.S. I am not likely to do high end Astro photography but may like to take a picture or two in the future…
@AVTAstro3 жыл бұрын
Hi, funny that you should ask because I'm planning my next video around the subject of "if I could only own 1 scope"! Beck to your question. Usually the bigger the aperture yes the bigger the view. And you are correct that you can get a bigger view with a 2x Barlow or in fact just with a shorter focal length eyepiece. Issue is that when you increase the magnification the image brightness goes down. A high quality refractor will be an awesome scope, but do keep in mind that it can only be as awesome as a 120mm can be(I say this owning the best 102mm and 130mm in the world. Amazing scopes but still only a 4" and 5"!). If you are more into looking at the moon and planets 120mm might be all that you need. If you are more into smaller deep sky objects than in all honesty you are very likely to want a larger scope eventually. The best solution is honestly not 1 scope. Its at least 2!!! 1 wide field, like a 80mm-102mm APO and the other a light bucket(8"+) for the small stuff!!!

you did not mention the major feature of the other scopes why they perform the way they do. the FSQ106 Takahashi is a Quadruplet, (4 lens) which flattens the field with that 4th lens while the triplet tightens the stars and your images will have brighter but also tight stars with the HDR contrast. A televue Quadruplet will perform similarly well. That's a HUGE difference to a doublet and a major advantage to even a triplet. What you pay for a Takahashi is the workmanship where most scopes are performing at 98% or more. You get what you pay for while other brands will have a variation in the manufacturing and workmanship. Pick up a Skywatcher or some other brand and the scopes will be sometimes luck of the draw on fitment, finish and performance.
