Manufactures of good long focaL length refractors
      #5652757 - 01/30/13 04:51 PM

Are there any makers of decent long focal ratio refractors left? If so, who? What would you suggest?

Thank
Bart

Surely you have heard of this:

D&G

I have a 5" f/12 and it's quite excellent. Took over a year to arrive though.

I have even seen a 5" F12 triplet

then there is ISTAR who makes long focus achromats.

Trying searching on Google. You would be amazed what you can find

These are definitely beauties. The maker is a member of the refractors forum. You can check the buzz on them over there.

Very nice. But, all are out of my price range. I forgot to include "reasonably priced" in my question....

You buy a reasonably priced telescope you get optics that are reasonably good.

I suggest you try the Surplus Shed and buy a Jeagers 4" F15 lens for $100 and then get some tubing and focuser and get crafty. Otherwise, you will just have to go without.

Sorry, but it is the sad truth. Well, unless you get lucky on Craiglsist and find a great deal.

I got to know Richard 2 years ago at Neaf. He brought two refractors with him. He sold one, took orders, and had to move the other before he went back to England. I could kick myself now. I think he finally got $695.

Johann, I just bought one of the remaining Jaegers 4 inch f15 lenses two weeks ago. It got a premium and not a second and it was priced at 150 bucks, but with the sale of 30 percent off I did get it for ~100. Thet were going fast though and I just checked the Shed a few minutes ago and no more 4 inches were for sale, not even seconds.

That's interesing Terra. I ordered the 103mm Jaegers objective, SKU L10607J, from Surplus Shed on Friday 1/25. My price was $149 and I had a code for 30% off.

I look now and that SKU is unavailable. I've not received any notification of it not being available, but I've also not received a shipping notification.

My goal is to make my own F/15 refractor.

The 103mm F15's seem to be very good as a lot, never heard any complaints and I have two good ones. I did have trouble witha couple of 82mm lenses. Fred did exchange them.

I'm a total newb in the world of DIY long F/ refractors. Is there a 101 website that you'd recommend to someone that want's to build their own? Are good lenses no longer available? Where does one get a good lens? Sorry for my simple questions.....

You can find lots of good information in the Refractors forum and also the DIY/ATM forum. Be forewarned though, a lot of the folks over in Refractors are into modern short focal length ed apos, but there are some of us long tube achro freaks there too.

I have a short focal length scope and I've very happy with it. I'm simply at the point of wanting to have a long focal length achromat to see what that's like. And if I can make one for relatively little money, so much the better.

If you purchase a lens-in-cell (e.g. I-Star, D&G, or sometimes Surplus Shed) then you mainly need a focuser. These are nice:

Crawford Machine

Then if you can build a long, square box, or get a piece of metal tubing that fits the focuser and lens cell, you are set to go. (Still need a huge mount of course).

Do some searches in the ATM forum and you will find a lot of options.

and here once again found through google

I think you can handle it from here.

also we are going to get slammed soon for being out of context for not talking about classic telescopes.

The f10 and f13 Antares are discontinued. The f15 was well discussed on CN at one time as well, and those have been unavailable for even longer.

Not too many choices. The 103mm SS lenses seem to be gone now. Still some 82mm F15's left, the replacement 83 that Fred sent is really superb. Finally got a good 45 minutes of nice clear sky a little while ago. The 103mm F15 Jaegers is really good. GRS was clearly visible along with lots of festoons.
