Oof....that F15 looks mighty fine. I do wonder how it would compare with the 80mm F10 ED. https://www.firstlig...-telescope.html

 

However at half the price of the ED, I'd definitely give the F15 a shot. It's just a shame I'm more interested in a 4 inch and not 3 inch. I'm not so sure I'd be happy with less aperture than what my 90mm already gives me. It already sees a lot less use since I got my mak.

The Stellamira 80mm F10 is Long Pergn Taiwan and is very appealing. Strong r&p 2 speed focuser, rings, bar & sliding dewshield.

I was going to mention that one as well, but he said ~$700.  The Stellamira is 899 BP's.

Of the following three options, which would you choose and why:

 

1. Vixen made FirstScope 80mm in excellent shape

2. https://www.firstlig...-refractor.html

3. https://www.vixenopt...ope-p/26062.htm

 

If you wish to select an option not listed it has to be 80mm and no shorter than f/11 and cost no more than $700!

I had never heard of the Scopetech 80mm telescopes until I read this thread today, and after checking them out I ordered a F/15.  FLO in England is the only place I could find that has them for sale, and they actually had two in stock.  I paid $498 plus a not-too-bad $65 to ship it here.  I also got two Baader adapters that do away with the single screw drawtube clamp.  For such an interesting telescope, I think it's going to prove a bargain to me.  Very cool!

Congrats! I'd love to know what you think of it once it arrives. I had one in my cart for several days and saw them go from having 3 in stock to just 1 left. Made me wonder if this thread was to blame!! Alas, I ruled it out this evening so now I have to live vicariously through you mtminnesota!

 

Or... have you inspired me to take the plunge? I sure do go back and forth a lot about my next astronomy purchases!

Oh gee, I was eyeballing them too, but just as well as I don't think the price was right for me anyway.

Agreed, it was close but I kept coming back to the price/limitations just not quite making enough sense to pull the trigger. I'm super excited to hear from anyone who did buy one though. I think the TS 102ED will be more my speed when they're back in stock. I love to look at 80mm f/15's but have not been able to get over the hump to purchase.

80 mm f/15 1200 mm f.l., color blur ~2X Airy disc.  102 mm TS ED f/11 1100 mm f.l., color blur ~ 1.1X Airy disc.  Both scopes same length, 102 a little heavier, 102 > 0.5 magnitudes deeper, 27% better resolution, superb 2-speed R&P focuser.  What's to ponder about?

Daquad, not pondering between them — it’s both or one. Sometimes it’s not a competition and when it is, I usually just want bothgrin.gif

I would actually ponder between 80mm f15s or classic 76mm F15s

Got it.  I was referring to the posters in general.  Good luck with your choice.

If you are a somewhat serious observer (whatever that means), you should VERY seriously consider getting the 102/1122mm ED first. Then you could save up for a really nice, classic 76/1200 or 80/1200 achromat, and get that one, when a nice one shows up at a good price.

Let us know how you like the ScopeTech once you have it. I heard from FLO today that they've ordered more but have no idea when they might be back in stock. At least they're not gone forever...

I'll be interested to hear what you think of it. I used nothing but a 3" f16 Polarex from about 2003 until a few years ago when I stumbled across a Skylight 100mm f15. As I'm almost entirely a Solar System observer the Polarex suited me well and I could have happily used just that scope for decades more.

I'd like to give my impressions of it, but I've realized that I don't have room to store it in my current apartment.  I'm going to wait until I retire and move to the southwest in a year or two, where I can observe to my hearts content.  Until then, it will unfortunately stay in the unopened box.

This Takahashi FS60Q is an F10.  It has some pretty good reviews.  I received mine a week ago and just put it on the mount today.

I sure wish I could find a decent 80mm F10 achromatic doublet (not ED) with the ability to go 2" on the focuser. :(

 

Very best,

I meant to say that I won't be hurting for a telescope to use while the Scopetech 80mm waits in the box, but I see your point.

Hi Jon! If I may where did you find this information? Or is it a calculation of known data?

Thank you!

Hi,
I follow the topic closely. I consider a Carton 77mm f 1250 for purchase. Any comment on this refractor?
