At the bottom of the tube you have a curved mirror. It just sits there. The light will come down the tube and hit the mirror. As soon as it does that it wants to go somewhere, so it bounces right back up again where it came from, except now it will be converging onto a small area because the mirror is curved.

If you did nothing else, that light would just head right on out of the tube to be lost forever.

So, at a point where the light reaches a much smaller size, let's say you have the hypothetical 8" mirror, and the light cone has now been shrunk to about 2" a few feet back up the tube, you would put a diagonal mirror in the path of that cone of light.

That small mirror, set at 45 to the light cone, will shift the light cone to the side of the tube. At that point, we would make a hole in the side of the tube for the light to get out.

We would attach a focuser to the hole, put an eyepiece in the focuser, and tweak it until the image was in focus.

And that, in a nutshell, is how a reflecting telescope functions.
I got to tell you buddy, that plainly clears that up for me, I finally understand. I didn't understand why the mirror was concaved but now I do. Thanks Keith, I really do appreciate you buddy.

Jupiter is at one of the best positions for viewing this season. I believe I read that it is peaking now to be the best in 50 years. Now might be a good time to take a look, even with binocs. You should be able to catch Io, Europa, Ganymede and Callisto if you mount your binocs on a tripod. They are the four main moons of Jupiter. There are somewhere around 60 moons all told, and as our observations of Jupiter get better, they seem to find ever more.
I did see the moon tonight and it was close to Jupiter, well it looked like it was. Last night it was over cast so seeing anything was out.

I had no idea there were 60 moons, it looks like they would collide, well, I forgot how huge Jupiter is. This is really neat learning about the things of outer space.

The Star Quartz product is (supposedly) capable of use on vertical surfaces as it is, I don't know what my problem was that day but I had to fight with it repeatedly to get it to stay in the joints of an 18" high tub surround.

The company said to pour-off some of the juice before mixing, this will thicken the product somewhat. I wish I had called them before I knew I had a problem with the product staying in place on a vertical. Hey wait! That doesn't make any sense.

I won't even get into the use of epoxies. What a PITA they are!

The urethane grouts have been around a few years by now (I'm guessing) and I haven't heard of any real issues with them. They are slightly harder to clean up when installing but not the end of the world. Just don't try to use them on a tile ceiling - gravity is not your friend.

The Snapstone grouts are super limited in color availability and may even be a little higher-priced for some reason. Assuming their grout is still made by Quartz Lock these days.

I heard back this morning from Bobby Fortney at Star Quartz...they have a distributor over in Vancouver!!! Good show!!!

I have given Bobby the precise details of the job and requested he let me know exactly what it is that I need. Then I'll call the guys in Vancouver and have it mailed over.

Once again, many thanks for this info Bud.

This morning I did the same as usual, lit one of the wood stoves. At the moment I am just burning scrap wood and it doesn't make a lot of heat, but after a couple of hours the house is up to 20C or so.

I was a little more impatient today as I wanted the temperature to get up faster so that it is nice and warm for tiling the kitchen counter. I lit the second wood stove. This is the first time I have had both of them running at the same time.

Good grief Charlie Brown, at least I know how to get the heat up in nothing flat in future if we ever need to. One small load (junk wood) in the second stove and it is cooking in here.

Wood stove has been on for about a week here.
Light it once in the morning and once in the evening, but that'll change soon enough...

That is what we do in the cabin. Small cabin...small wood stove. It takes only about 20 minutes to get the cabin toasty warm.

hehehe, sorry bout that,

I just heard our winter prediction and it is going to be warmer than usual and a lot dryer. For crying out loud we didn't get but maybe 4 inches of snow last year and none for a few years before. I love snow but for about two or three days and it needs to go away and usually does.

It has changed a lot since I was a kid, back then it got cold and stayed that way all winter not like today, we may see lower than 30F but usually not for long. Back then it would get down to 0 and stay for a while. We depended on the weather getting cold and staying cold because that is the only way we could keep the meat we processed from ruining, we didn't have electricity back out in the sticks.

When you are talking F, 32 is zero C. Where we are here, we seldom go below 0C. Most of the winter our daytime highs will get to 5C or better.

When you shift inland, then the temperatures start to drop. And the opposite is true in the summer.

Here we may get to 80F - rarely - but up in the interior of the province it goes way over that. The ocean moderates our temperatures very considerably.

Wow, your area sounds like the ideal temps year round, at least for me.

The first of the three counter tops is now down with thinset. A bit nerve wracking when everything needs to be just about so.

I have tried my best to make sure the tile is all level with its' neighbour, and I think it will pass inspection by the wife when she sees it.

Now awaiting a return email from Star Quartz as to precisely the product I need for grouting. I expect to hear tomorrow.

Perhaps that is why it is so popular with lots of folks Jim.

Considering how small this island is, it is surprising how many Americans have property here. I mean, there are several Gulf Islands here, most of which are much bigger than this one. They have all the facilites, things like roads, electricity, stores, schools and so on.

But aside from the Americans, there are property owners here from all across Canada. I would say for the most part, the bulk of the weekend type owners are from the surrounding area.

If I were younger I would be up there also, from what I have seen it is wonderful.

Judy and I went out tonight and looked at the moon and Jupiter. That is the clearest we have been able to see the moons around Jupiter but all we have were binoculars, the moon is so bright it hurts your eyes to look at. I can't wait until I can get a telescope.
