I have reduced my classic scopes to almost a bare or bearable minimum.  I just had too many scopes, and most of them were not getting used.

I started a purge two years ago at about this time of year, and I may have completed it.  (maybe, I'm looking for a Sears 6345.)

My signature shows just about what is left.  I don't see any further reductions there.  Just about all of them give great views.

 

The first purge was started for 2 reasons:  1, to reduce my inventory; and 2, to buy an AT130EDT.

Well, I did buy the AT130, and it was excellent.  It gave great views, but it just didn't get used very much.  It left me wanting more aperture.

 

My 10" f/7 newt had enough aperture, but it was too heavy.  Rolling it down the driveway only gave me one window between the trees to view.  It was too much to take to an outreach, as it wouldn't fit in any of my vehicles.

I never had a SCT, so a few months ago I came across a Ultima C8.  It gave pretty good views, and found I liked the compact size.  It was more of experimentation, but I wanted something a little larger.

 

 I recently sold my AT130EDT only for the money to help fund a larger scope.  It may spend the rest of it's life taking photographs.

 

So now, I am thinking of maybe getting a Celestron 9.25, but there aren't any available at this time.  In the meantime, the remaining scopes are getting their turns.

"Have you look at a dob, lately?"

The design is old enough now to interest me and I'm having all kinds of fun.

My Coulter 8 inch 'Stumpy' started it, so much fun, like a giant Astroscan.

My latest one is a 20 inch f/5, let me repeat that, 500mm x 2500mm, and I'd

guess it's around 100lbs. It wasn't long ago a 20 inch f/5 would weigh over

a ton and need a permanent observatory.

I think Robert has an excellent idea. If I were ever to get another telescope (big if), it would be a 10” F5 collapsable or folding dob.

 

And yes, as my signature shows as well, I’ve done a major cleanup or clean out! It feels good.

I completely understand the “purge” thing and went through it several years ago. I was up to 23 scopes at one time but eventually sold off almost everything and have got it down to just a few of my favorite, most used scopes. I am EXTREMELY selective now in my purchases, (although the urge is still there for many). I’ve actually done more trading recently than buying/selling with someone local. Soo much less hassle than, tear down, wrapping, boxing, shipping, etc. IF I were to buy another, there would have to be very compelling reasons and one would HAVE to go so I don’t end right back where I was. Right now I am quite content with my TV Genesis and 74 Celestron C8, they are my two most used. They compliment each other and do all I need from them and I don’t see that changing anytime soon. 

 

Although another Criterion RV-6 would be nice. Then I’d have 500mm, 1200mm and 2000mm focal lengths, each with their own strengths to cover all of my viewing. 

 

Ive recently gotten into (vintage) binoculars (they take up way less room) but that’s another forum, lol.

 

Good luck on your quest.

I agree, I had a 10” Cave F6 and the views through it were truly amazing. It performed well on just about everything. It truly is the one scope I regret selling (view wise) but as Gary stated that size scope is/was a BEAST and the main reason it moved on.

Same here -- now, I can actually see the floors in my Man Cave and in the Shed.  I'm still down-sizing, but the choices get tougher as the total number shrinks!  I could get by without my RV-6, as the 826 has more capability without much hassle.  I don't use my C5 Astro often, but I might if we ever have normal weather again...  and, I like having at least one of each scope type -- it's my only SCT now.  The Hy-Score 457 is a nice display -- I have it set up to the left of the ultra-massive Tinsley for a David & Goliath presentation.  But my Tak FC-50 makes all my 50mm fracs redundant...

I've thinned things out too. But a 8-10 inch Dob should be considered. Recently sold my Z10 Dob because for me at 72 it was just over my comfort level to move and set up. I replaced it with a 8 inch f/5.9 Orion Dob. Good decision, its two components are well within my physical comfort zone. Had some of my best views of Jupiter and Saturn with the 8 inch just a few days ago plus I can easily load it into my car or truck for dark sky viewing.

Maybe 6 years ago, maybe more, I sent all my classic scopes to new homes. I liked the scopes but I wasn't using them and I felt they deserved more than just sitting on my shelf or in a corner. Since then, a few have come and gone, enjoyed for a while.

 

Now I own only one classic, my third 60 mm x 800mm Asshi-Pentax.  I really like these scopes, the mount and the optics are excellent.

 

But I have a new system, it'll probably be quite some time before I part with this one. I bought it from Chuck at the beginning of the pandemic and I'm still waiting to decide if I should have him ship it or if I will pick it on my way up to see our son in Lolo, Montana.  

 

As long as Chuck still has it, it's unlikely I'll give it away but stranger things have happened.

Yes an 8” does sound a lot more doable opposed to a 10”, as I’m just one year behind you Bill.

 

Thanks Charlie and Steve for the B-Day wishes.

Happy Birthday Terra!

 

I just sold TWO 10" Orion dobs (XT10), and a 10.1" Coulter red tube dob in about the last 3 weeks or so. About 1 a week. This size has hit a real popular mark nation wide. The solid OTA tube will fit across the back seat of most cars easy. A 12" size (XT12 or 12i) will NOT fit across the back seat of most anything including my full size pickup. 

 

Another aperture option is an 11"  CAT like the Celestron C11.   Going from 8" to 11" will give you some WOW factor and you get all the CAT compacting. The 9.25" has always been the odd ball for popularity and availability. 

 

A classic 10" dob is more likely to have a longer focal ratio and more likely to not fit in the back of a car - or even pickup seat. My Coulter red tube made a happy camper buyer.   I think I'm down to about 50+ over the last couple of years, from well over 100 'full' set ups not counting the parts is parts.  Thinking bout chicken now.

I have reached that point in which my collection of classics will remain as is for a long while. The milestone was the Sears 6336 (thanks again Barry) that completed my 1960s Sears refractors family group. Any other telescope coming in will require another going out and that will not happen in my classics department. At this stage in my life I am into smaller scopes. My two big ones, the RV6 and the Celestar 8 were a gift and a  cheap one respectively. The RV6 is on wheels and the C8 is thankfully an easy setup on it's wedgepod. A 10" Dob? Not unless someone comes in the night and deposits one on my driveway. I couldn't leave the poor thing out in the weather, could I?

 

Happy Birthday Terra & Many Clear Skies!

Here are some carts I've bought or built to make large telescopes pain free and

ready to observe in minutes. Even a small dob can be heavy.

All were or are a complete success except for the one under the brown tube

Coulter. This one was a wheeled base for a IV stand and wanted to roll when

moving the telescope in azimuth. 

The blue cart came from Harbor Freight.
