Quote:Just think of the gasps (awe, astonishment, disbelief, who knows; they're refractor folk) when you mount that $8K refractor to the Newt/Dob as a finder scope....... at least they can console themselves that at $8K, the coloring should be minimal...unlike us poor dob folks, whose idea of coloring involves paper and crayons........

What would the point be? They would be such different scopes that the result would be obvious from the outset. Jon

Quote:But I think scopes, reflectors or refractors, with apertures less than about 3.5 inches will prove disappointing to most people in most observing situations.

Quote:I know this thread is mixed with both humorous and serious posts...This is a serious post... I own a refractor that cost someone about $4000 and I own a reflector that cost someone considerably more than $4000. I use them side by side. Comparing them to each other would be like doing a comparison between a 1000cc MV Augusta motorcycle and a Peterbuilt... If you want to go 175mph, the MV Augusta is a good choice. If you want to haul 30 tons over the mountains, I would go with the Peterbuilt...A formal comparison between the two is not really necessary to make this determination.Jon

Quote:With the current economic outlook, I'm not too excited about putting much new money into the hobby. So when I think about the money tied up in my refractor and GEM it occurs to me what an awesome 8" RFT I could make, starting with a Zambuto primary. I'd probably have money left over for an equatorial table. Optically it would offer wider field and aside from double stars it could probably do everything better and be a better grab-n-go.

Quote:When you say the 8 inch RFT could provide a wider field of view and be more portable, in comparison to what?
Quote:Hmmmm, I dunno. I've built quite a few RFTs and I was surprised how well my 6" f/8 achro performs in this role. Without the shadow of the secondary to fool with I can easily max-out the exit pupil. Also, nutt'n cools faster than my achro and for a big scope it's surprisingly easy to setup and put away. Okay, my LightBridge 16 comes in a close second, but I keep it outdoors, so that's cheating.

Quote: Quote:But I think scopes, reflectors or refractors, with apertures less than about 3.5 inches will prove disappointing to most people in most observing situations. For me, avoiding disappointment is a question of having reasonable expectations and sufficient understanding to choose the right scope for the task. My most recent love affair is with a "lowly" 80mm F/5 iOptron achromat. When I finally figured out I could replace the plastic focuser with a 2 inch Crayford from my parts box, I was in love. Sure, it can't do some of the things that a large Newtonian can but the it is also very true that the large Newtonian can't do some of the things this little scope does so well. The 31mm Nagler provides a full 6 degree TFoV at 13x with a 6.2mm exit pupil. For those who only want to observe small objects from a list, not a good scope. For those who are interesting in seeing the sky beyond what the old masters saw with their narrow field eyepieces and long focal length scopes, it's a whole new world...

Quote:Jon,My concern is for beginners who buy refractors hoping they will see galaxies and globular clusters high magnification images of the planets.There are two levels of disappointment founded perhaps on misrepresentaton by refractor marketers.One is the boat of hundreds of power magnification on department store refractors. This turns a lot of people away from astronomy because of the disappointments.The second is by manufacturers of decent quality, or high quality, refractors, who try to lead the beginner to think that a small refractor is a good first telescope. I think it is not, it is much too small and will lead to disappointment.A third case is that of experienced amateurs like yourself, who already have large reflectors, with their limited fields of view, and want a small refractor as an additional scope for wide field views. This is the kind of person a refractor can help.The first two cases are regrettable and it is about these that I am complaining.All the best, I always enjoy your posts,Bill
