Going the traditional route: This kind of telescope will always be a classic!
You are also a craftsman and the work looks excellent!

Wow, what a beauty! And in Tasco Red no less!

Do you have a paint code for that?

How did you find the hastings tube for prep? Were there many defects (dents, etc.) that had to be taken out?

Again, really nice! I like the 6" F10 size. They are still manageable (although not small) and have the nice classic long refractor look. If you don't have one already, I recommend a long FL Plossl (Meade 56mm, TV 55mm, etc.). They work really well, give huge fields, well corrected and not to large an exit pupil.

Clear skies,

Beautiful paint job and overall nice job! I also like the handle/finder mounts made out of aluminum square tubing. Great idea!

I have a Jaegers cemented 4" f/10 lens in a homemade tube and it is an excellent performer. False color is not objectionable, and the reasonably short tube is very easy to deal with.

Thanks, guys!

The color is actually orange (for some reason, it's called 'sparkle bomber orange'). I don't know if it's because it is powder-coating rather than traditional paint, but it has a lot of depth, and a certain amount of prismatic effect. I took the photos not long before sunset, so that may have made it look more red. If you look at the focuser photo, it shows the true color better.

As for the square aluminum tube, I was very pleased myself with how easy it was to shape, and the overall look when I was done with it. I wanted a metal handle between the wooden cradle rings, but didn't want to pay what they cost at Home Depot. Once I decided to use what I had, the design sort of followed from the shape of the tube, and my wanting to cut away the holes I had drilled in the square tube for some old project.

Oh! The Hastings tube was not bad, especially for the price. There's one small ding in the main tube, which nearly went away with the powder-coating. I did have to sand the ends a bit to get rid of the rough edges, but it was quite square, which had been a worry. Some lines also show (barely) along the tube, where the manufacturing (and more of my sanding) did not quite make it smooth. I'm almost glad it isn't perfect; this way, maybe I won't be quite as insane in how careful I am with it!

I was going to say exactly the same thing. I really like how that turned out! What an elegant way to turn a rather spartan, even ugly square tube into something attractive while still being very functional! Gives me some ideas... ...like how about putting hardwood inserts inside the tube, fer instance!

Love the red tube, too!

Wow! That turned out nice!

Is the 127mm lense? What size tubing did you buy for the dew sheild?

I like the idea of hardwood inserts, and will give that some thought. However, the opening in the handle actually seems to work as a rough finder; sort of a very poor man's Telrad. I plan to buy a G-11 to put this on, and I tend to push to objects. I want to see if I'm right about rough alignment with the handle (skies are supposed to clear tomorrow).

The tubing for the shield is 8-inch; the main tube is 7-inch, for the 6-inch lens. Dan Crawford originally thought he'd be able to make the cell take a 7-inch dew shield, but later wrote to say that 7.5-inches was the smallest he could get it. In the meantime, I had ordered and started finishing a 7-inch shield. I've attached a photo. If someone wants it, I'd be glad to pack it up and send it for the shipping cost. It's a 7-inch outer diameter pipe, with a .060 inch thick wall; nine inches long. Unpainted inside and out, but sanded with 320 grit. The cap was also made to use the solar filters I made for my 5-inch scopes. The photo doesn't show it, but the cap is made from a thin ring of birch plywood, with a thinner piece glued on the front.

This reminds me of another idea I had for a zero-power finder. And it might work in this case, too. I make a lot of my tubes out of plywood, so they're polygonal. Even with just a semi-gloss polyurethane on them, I can sight along the tube and line up on a bright star or planet by getting its reflection to converge with the sky view. So, you could probably do the same with your square tubing, even if you were to put inserts on the inside, by sighting along the outside faces.

I should note that this worked so well with my 12.5" f/23 Cassegrain that it was more than a year before I put a finder on it. Just sighting along the tube sides was enough to get the object in the field of view of a 28mm RKE at the Cass focus (the telrad in this pic was added later):

I keep reading and misreading your dew shield post. I think I can make use of the 7" dew shield if you have not gotten rid of it yet. PM for details.

I've built several other scopes, but they were all of the just-so-it-works style. Nothing very handsome. This one looks nice enough that my next project will be to build a well-padded, solid case for it. With wheels on one end. (The scope is pretty massive and unwieldy.)
