Hey guys, on the other website I saw an ad that APM will be bringing out a cheaper ED doublet lens that you can replace your achros with. Now before starts freaking out over Chinese lenses or 6" ED doublet will be more like an achro thus not worth anyone's time   . I contacted Markus and he said that the lens will be made my LZOS and will use use OK-4 glass (the glass that people say is like FPL-52, while it is actually between FPL52 and 53, closer to FPL51 though  )

He announced that here in the Vendors section also. It was a suggestion I made to him when he was soliciting ideas a few weeks back. I figure some others probably recommended it also.

Hey you think a GM8 would hold a C6R?? ;-)

I think this is great. The most advanced triplets are really beyond what most visual observers need. A 6 inch f/8 refractor can be a great visual instrument for its size and weight. The tube doesn't need to be huge with a 4 inch focuser and the lens doesn't need perfect color correction.
The OK4 LOMO doublets sold by Stellarvue and others in the past have been excellent performers, I'd expect the same from LZOS

The number that I've heard was under 1k for the lens set. We'll see.

I doubt that cheap, APM doesn't have a price yet. Under $1k, maybe for FPL51 Chinese lenses (even then, I doubt $1k). The reason I doubt that is because the lenses are going to be sourced from LZOS...and also, you guys think a GM8 would be up to a task for a C6R for visual?

I don't think the GM8 would be very efficient for something as long and heavy as a 6 inch f/8 refractor, even if it is built light. I have a C925 on one, and it works fine for lunar and planetary imaging, but is pretty bouncy for focusing.

Anyone have a link? I'd like to keep track of this!
While my current C6 has a Chromacorr, I think replacing the doublet would probably be more effetive, particulary off-axis. Off-axis is of particular import to me-- I only use undriven alt-az mounts (hate gems).

Wow it looks like it sits pretty nicely!! I also have the pier extension for the GM8 so the height isn't an issue...

Hello All,
In 2 weeks I will be in Moscow visiting LZOS and discussing with them the new projects. We send ahead the optical layout and will ask for a rough price quote.
As soon we have news I will announce it on the vendor forum, keep your eyes open
thanks
Markus Ludes

Ok, for those who will be starting from scratch (estimated.)
(1) Used Celestron 6" F8 450.00
(2) APM Lens set 1000.00
(3) Moonlite Focuser 275.00
Total $1725.00 +/-
Not bad for a nice 6" LZOS doublet. Even if the lens
set is $1250, it would be good.

If you can be happy with the stock focuser (I wasn't, got the Moonlight) you could be getting an even better deal.

Again, I highly doubt the lens would be a thousand...even if it was a Chinese made FPL-51...but if it was that cheap....HOLY COW!!!!!!!!!!!!!!!!!!!!!! I will be all over that like flies on dukie!!!

If you replace the objective lens in a refractor, wouldn't it be beyond most people's experience to get it collimated? I can collimate a mirror but have never tried to collimate a refractor objective and the thought sort of scares me. Better a well collimated achro than a miscollimated ED or semi-apo or apo or whatever... but maybe I'm just being too cautious and maybe it would be quick and easy... I just am not sure...

And don't forget that you can probably sell the original achro set to recoup some dough... - j
