My recommendation would be to go for a series of Plossl e/p's. They are available in sets which give you a decent range of powers, and are normally reasonably priced. You may find them packaged with a set of filters, but don't be fooled by a bunch of pretty colours unless you know what the filters are for.

Stick with the e/p's first.

You may find that one manufacturer provides several different brands - which may well be differently priced. So do a little homework first before you lay out your gold.

Here are two 32mm Plossl's apparently from the same factory. Just different brand names on the barrels.

This one is a true economy e/p...the RK stands for Robert Kellner who designed the original versions of them many years ago.

They do an OK job, but with modern Plossl's and the very small price difference, I would be inclined to standardize if possible.

A large part of the difference in these e/p's is in the number of elements each one has. The greater the number of elements, usually the better the view. And, of course, the price will climb.

Here's a big 2" e/p, 38mm focal length with the little 6.4 for a size comparison.

I do have the magazines here with the impact story well written up...let me see what I can find and I'll get you more details. As the comet approached Jupiter, the extreme pull that Jupiter exerted on the comet literally pulled it to pieces.

That is really interesting, I hope you can find that article. I am really enjoying these tips and information about our solar system. Thanks buddy, I do appreciate your time and talent.

I have the tips in a file now and can read your tips until I can get the book.

I'm recovering OK from the dentist yesterday, and feeling more like doing some more work.

Going to have a go at assembling the door, so if that works out OK there should be a pic up later on. So far it's not looking too bad.

Then while that is drying, I'll get back on the kitchen cabinetry...which is taking far too long. Last time I will be making any round cabinets I can tell you!

Speaking of telescopes . . .

A local professor built and maintains a fantastic DIY observatory: the Abbey Ridge Observatory.

If you're interested in kicking your skygazing hobby to the next level with your own observatory, check out this link showing how he built it (it's actually a fun read even you don't want to build an observatory): http://www.davelane.ca/aro/phaseone.html

Quote:
The observatory is housed in a Technical Innovations 10-foot Home-Dome and uses a Celestron C14 SCT mounted on a Losmandy Titan german equatorial mount controlled by a SiTech controller. An SBIG ST8XME CCD camera with Optec IFW filter wheel and TCF focuser are used to image the heavens. We also have a Boltwood Cloud sensor.

Round cabinets? As in not just somewhat curved, but actually round? That sounds like it would involve some complicated joinery.

Will they be used as an island (sorry if you already mentioned this, I have trouble keeping up with this thread :D)? I can't picture any way to wall mount round cabinets. Unless the kitchen itself is round, which I wouldn't put past you.

Most interesting indeed.

We have the same telescope out here at the Vancouver Island University. The scope is actually owned by one of our astronomy club members along with his SBIG camera, Kendrick dew removal goodies and so on.

I designed the observatory several years ago with a roll on/ roll off roof. At the present time the club is building a 20" (half meter) telescope which we hope will be used in public outreach.

The kitchen counter itself is based on a portion of a circle. It is slightly less than half a circle, so it is indeed very round. There will be no wall mounted overhead cabinets, only floor mounted units with this one.

I could have made it octagonal, which would have made the cabinet making far easier. But why do that when you can spend twice the money and take five times as long to do it this way?

Ah - but just think of all the money and time you're saving by building circular cabinets instead of spherical ones!

Oh my stars, (sorry) you designed an observatory? I was right, there isn't anything you can't do, buddy, I am impressed to say the least.

Judy just looked up the observatory here in Chattanooga at the University of Tennessee and we are going to try to make it to see it here soon.

Building the radius cabinets would be fun, just plane ole cabinets are boring to build. I hope you get over the soreness and pain quickly. We are looking forward to your pictures, when you feel better.

Ah so...never thought of it that way.

Where do you suppose I could get a quote on these?

Well Jim, it was like this.

We were forming a registered society, the Nanaimo Astronomy Society for the record, and it was suggested that it might be a good idea to build an observatory.

So I said...well, tell me what you need this building to do and I'll draw it up for you. I took the plans to the next meeting, and the rest is history as they say. We were able to use a small piece of land at one of the campuses on Nanaimo, and over the course of the summer, we constructed a perfectly serviceable observatory. I houses a 14" Schmidt-Cassegrain scope with every bell & whistle known to mankind. It has a roll on/ roll off roof, and it has a warm room where the computer sits to control the scope with.

The whole setup has been used to take some spectacular astro photos with. If I can find a pic I'll put it up, if not maybe I can give a link to the club website.

Wow, I have drawn many house plans but nothing like that, I wouldn't have a clue where to even start. Having a huge part in something of that magnitude is just too cool. We would love to see pictures if you can find them.

If you promise not to tell anyone...it was the easiest building I ever had to design. Except for the moving roof part. But we figured it out.
