A 6" or 8" newt on a 1.5" shaft mount is a steady scope and not much less portable than an 8" sct, and more portable than a 10" or larger sct. A 10" newt on a 1.5" shaft mount is starting to get a bit undermounted, but is comparable to a 10" sct for setup - easier in fact if the mount is on wheels and being rolled in and out of the house.

My 8" oc connoisseur is rock steady. It's also easy to transport, as the legs are aluminum and mount to the pier with thumbscrews from the outside.

My nexstar 9.25 is a pain to set up on the wedge in the field. Definitely less portable than my 10" f/6 newt on the Tak em-500 mount, and even more so on the njp. The em-500 is far steadier, though, so I prefer it for my bigger scopes. Of course, I also prefer vehicles I can sleep in, so most also have room for the larger scopes.

Nice scope. I have an 8" mirror I keep planning to put into a tube. However, I think it is an F12. I am thinking of just using a 8 foot 2x4 and get creative or build a folded refractor. Hmm does this require a new post

For visual observing, chuck the wedge in the comparisons...

And really, the comparison is between a Dob mounted Newtonian and a GEM...

I can setup my 25 inch F/5 Obsession without outside help. In fact, I prefer to do it by myself but with someone standing watch just in case. I cannot setup my 12.5 inch Meade RG without someone to help...

Comparing my 12.5 inch Dob to the 12.5 inch on a GEM, it's a no brainer, the Dob is a truss with a 19" x 20" foot print that it 28" tall with the upper cage is nested.

The world has changed in the last 30 years.

Well, there's that, and then there's the fact that my vehicle can't go over about 60mph on the freeway, and 35 up the grades! That didn't use to be a big deal, but now with everybody in their Lincoln Navigator SPUTES driving to Vegas at 90mph, I'd be squashed like a bug before I (or they) even knew it!

You have a VW van thing with a flatbed right? Driven a few old VW vans.. Slow does not describe the experience.. Glacial... Yea, it's not suitable for today's traffic ( really wasn't back then either) Still love to have one though.

If you think that is slow...

Back in the 70's when I was hauling hay, I had a loaded setup of doubles out of California City. Pulling out of Kramer Junction towards Adelanto on the 395, some guy with with a VW-Microbus towing an 8 or 10 foot box trailer passed me.

Of course I was not concerned about being crushed by an errant SUV driver.

VW still makes them, but VWoA doesn't import them

This one's even a 4x4:


I still have my 2001 Eurovan weekender. With the 201 hp V6, it's nothing like the old transporters on the grades:

In 1969 I was finishing up my army time in the DC area. To get around I bought a '58 VW bug. Top speed was 62 mph. Under no conditions would it go faster. Fortunately traffic on the Beltway didn't move very fast. I often wondered if VW chose that speed because it equals 100 kmh.

All I have left to do is fix the overdrive and the air conditioning and this will be my telescope transporter.
Its a superb automobile. Huge cargo area and a soft coil spring suspension. Very good on fuel 4cyl. My wife calls it "the banana".

Is that a ...? Never mind!

We had a Volvo sedan about that vintage for my daughter when she first got her license. Had over 200K miles on it when we got it. Great car. Probably saved her life when someone's tire blew on the freeway and they spun out in front of her.

My pickup is great for hauling that 12.5" Observatory Cave. I don't have to lift anything really. I used the cherry picker to lift the eq head, but I've been thinking about mounting one in the back of the truck so I have it with me all the time. Then, I'll just have to make it a bit more gutsy by either building a performance VW engine for it, or swapping in a Subaru or something.

I once saw a 67 VW crew cab with an Olds Toronado 454 cu in V8 and transaxle mounted under the bed. I bet it was hard keeping that one on the ground!

My days of wrestling big ,long and heavy Newts are over. My 12.5" F/8 was around 140lbs for just the OTA. Parks did a great job building the OTA around the Telescopics mirror, but it sure was heavy. This pic was taken in 1990. I waited for 2 years for Telescopics to build me a 12.5" F/8 OTA. After many calls to Telescopics and getting SKY&Tele on their butts i at least got the mirror and sent it off to Parks to build me the OTA. Telescopics closed the door soon after i got the mirror.

I had a 240 5speed a couple years ago, really liked that car. My next door neighbors son and daughter in law have it now. IpD springs, Bilstein shocks and VX cam. Still not fast, but a Ferrari compared to an old VW bus. My home built Lotus has 240 drivetrain. Motor , trans, rear diff, about 40 more HP than stock. Car weighs 1375 lbs curb.
My favorite slow car was my Fiat 850 sedan. 817 cc of sheer speed. It would do 80mph though. I did put my 6" F8 in there a couple of times.

I took a couple telescopes and camping gear up to RTMC in the back of my 31 Panel Delivery one year. With the overdrive (gear splitter, really), I could get up to 28mph on the mountain.
