If we're talking about the "golden years" time period (who came up with that term anyways?), I would stick with my SW120ED.  It is lightweight for its size and the views are great.  A 130mm apo would be better perhaps, but it would no doubt be heavier and therefore less desirable for me.

I am 53 years old and have been thinking about the sad day I may find my Tec 180FL difficult to mount.  I exercise and do small weight lifting so that I am able to manage the Tec as long as possible.  I figure if I observe every day I can, I am also getting good exercise just mounting the scope and carrying all my accessories.  I tell my wife and 2 children that I exercise for them so I may be around a long time but it is really for my scopes......  OK, of course, it is for both reasons!

 

Once I can no longer manage the Tec 180, I wonder if I will then try to get assistance to use it or find a way to keep it more permanently outside or just use my TV-140 more.  It is a Petzval design and gives beautiful flat views and is not too bad on the moon and planets.  It is only 15 pounds and very well-balanced because it is a Petzval.  It is very easy for me to manage and works quite well on lighter mounts.  I really enjoy using it.  Even the brighter DSO are enjoyable.

The TV-140 is the middle scope.

Due to orthopedic problems I faced a 25-pound maximum lift restriction as a young man in my 20's.  I decided at that time my favorite 25-pound scope was 6" apo.  You can ease the setup burden by going with a simple alt-az like Kent, but that one deadlift of the OTA weight remains.   I like using the Mach1 EQ mount because it splits in half and gets me below the 25-pound limit, a DM6 or T-rex alt-az head is under the limit too.

 

I've always thought when the 160 becomes too much I'll step down to a TEC140.  Or maybe even a lighter 6-inch, my AP160 is ~30 pounds.  I think the FS152 tubes are 22 pounds, some are even lighter.  

 

actually the 160 is often too much for my arthritis now, my "B" scope is a 120mm apo on a Tak Teegul mount.  Under dark skies it's a good DSO instrument, the heaviest component is only 12 pounds.

For me, this would be a light 4in doublet. Something like my former SW ED100 or Tak 100 DL.

Ideally ... a 40-inch, f/18.6 Alvan Clark refractor. wink.gif

 

Realistically, a TEC160FL.

If I could only own one scope and one refractor....I would choose to leave this cruel world.

Anyone know the times and locations of the refractor anonymous meetings?

Well, one scope AND a refractor.  My 6" APM ED doublet is about my limit for hefting a scope to the mounting rings.  I work out on a regular schedule, so the scope weight is not, and should not, be a problem for many years to come.  But I still like a larger aperture for those globs, nebulae and planetaries.  So a 10 -inch Newt on an equatorial is my other scope.  Weighs 10 pounds more than the 6" APO, but I don't have to lift it over my head.

If I had to have only one scope, and it had to be a refractor, I guess I'd opt for a 102-110 triplet APO. I could (and most importantly, would) use it well into my senior years due to its relatively light weight, yet reasonable aperture. The mount could be relatively light and portable. I could do visual, live video and astrophotography. I do come somewhat close here with my ED-110, so I have some user experience with this size scope, and it's all positive.

If I could have one scope and the refractor I would have an SCT 11 Edge HD on a AVX or better mount and the AT 130EDT refractor on the AVX. One scope and a refractor that is what I would have. But in the meantime I would stay with the Nexstar 8 SE and the AT 130 on the AVX

Lots of nice responses.  

What got me thinking is that I am 61+yo now and am looking at retiring soon (hopefully in 2 years).

We have been making life changes to get ready ... sold/downsized the house last year, moved to a location that is more

elderly-friendly.  

  My commute is killing me .. ~1hr each way  ... and I'm really starting to feel every pound of scope I have to lift as well.

 

Also, I'll be on a fixed income in a few years and I think my days of horse-trading scopes will be mostly behind me.  

I want to be done and settle in with a lifer scope (Hah!).

 

I've always been a one-scope guy and have taken to refractors (apos) ... for pure visual use.  My AT130 has been an awesome scope.  I bought it last Nov/Dec and to be honest, the optics have been way better than they have a right to be, given the price.

 

So this has been a thought experiment as I look for forwards towards my "golden" years.  

 

I think the sweet spot for me is around 130mm.  

Wow, your post sounds exactly like me... Too much commute time, and work stress

But I'm about 5 years behind you.

The good thing about the commute is having plenty of time to contemplate what scope[s] I'd like to have when it's time to downsize.

At this point i'm thinking either a good 10 inch Dobsonian, and a NP101, or maybe a C8 and my TMB130...

And these days, after 30 plus years of observing, If I can't see it from a dark sky in a good 10 inch, I'm not that interested in it.

If money were no object, I would choose a TEC160FL. It's big, oil spaced for fast cool down, and doesn't exceed my luggability tolerance. And it gives BREATHTAKING views.

My Takahashi FC-100 DC. The weight of the OTA is only 2.8 kg, and the quality of the fluorite doublet is fantastic.

Probably the TV-85, maybe the NP-101.  However, I had an NP and sold it.  I *have* the 85.

What would it be?

I don't understand this question. Define "own". Do you mean possession? Or are we talking about legal title? ;) 

 

Do I have any friends on this deserted fantasy island and can they have a scope?

 

Is there a NEAF on the island? What about a shop?

It's gotta be big, so my idea of astronomical nirvana is a 9" f15 on a mount I built...steampunk all the way.

It can't be too big or I'll never get out and use it. I'm only visual observer so a doublet is fine for less weight, less cost, and quicker cool down. So I'll go with something like the Stellarvue Access 102. A 4" is probably a good size for me that I'll use frequently. Plus I know I'll get good optics, good mechanics, and good tech support from the company.

Hi Rob

Our paths are uncannily similar: I'm 61 too ( born Feb 56), hope to retire by end of 2018, just downsized house in March, I have over a one hour each way commute plus further travel for work..

 

I've thought for a long while that a good 5" refractor hits the sweet spot as an all rounder scope. And just 2 weeks ago I was lucky enough to acquire my own dream "does it all" scope, a mint Tak FS128 F8 apo..I haven't even had first light yet, due to bad weather where I live, but I know it will thrill me and keep me busy with lunar, planets, doubles and clusters, ie those objects that interest me most. I will never afford a better scope in its aperture so I can stop looking at other scopes now and just enjoy observing.

 

It seems to me that your current scope might well fit all your needs, health permitting, for another 15 years. 

 

Whatever you decide, I wish you a long, healthy and starry retirement!

 

Dave

I feel a bit guilty - I retired at 51 blush.gif

 

I've used all 4 of my fracs on successive nights under the decent skies we have been blessed with recently in this part of the UK and I'd be mortified if I had to pick between them right now undecided.gif

 

Tonight it's the turn of the Tak FC-100DL cool.gif

TOA-130 would win for overall visual + AP use. For AP only, FSQ106EDX.

I've owned a TOA-130 before.  Too front heavy and, too heavy in general for my liking.

Maybe for AP but, for purely visual I would look elsewhere.

Dave,

  I am jealous.  I've always wanted to try a FS-128 but, have never seen one.  I've owned a few FS-102s. FC-100s, and an FS-152 but the 128 has eluded me.

To me, it's the perfect size/aperture.  I hope you keep it and enjoy it for many years.
