Nice shot Mark. I see you use the FZ20. It's my favorite camera. Which teleconverter are you using? I've had good luck with the Olympus tcon 14B, but I'm always interested in more power. -Kurt Horsley

Good point Steve. You're right.
Nice shots by the way. The bufflehead's are really beautiful ducks. We have quite a few of them in Texas this year.

A good focuser for the Orion ED80?

Posted By Kurt Horsley
I would recommend using the one that came with it. It's superbly smooth, and will carry several pounds. The fact that you can push/pull it by hand is not a problem, it's a characteristic of all crayford focusers. I use mine with a big SLR and haven't had any trouble at all. I keep hearing a lot of complaints, but just don't see the problem. Crayford focusers will never actually "focus lock" but they work fine.
Have you tried using the original yet? -Kurt Horsley
ps If you remove the original focuser, sell it to me.

Here...maybe this one looks better. Same photo. Photoshop can hide a lot of mistakes. -Kurt Horsley

A few set screw marks!!!

Posted By Kurt Horsley
If the optics are in good shape, it's still a good eyepiece. Probably worth at least $60. Upper and lower barrels are easily replaced. I've bought dozens of new ones for between $1 and $4, brand new/unused. I often replace barrels with "user" barrels and then replace the original when reselling. They're available for $1.25 from Bill Vorce at The Telescope Warehouse.
The eyepiece is still usable. -Kurt Horsley

Orion 80f/5 vs. Orion 100f/6 vs. Cel. 102f/5

Posted By Kurt Horsley
Hi John,
I've used all three scopes you mention, and they all work fairly well till around 15X, when the chromatism becomes too objectionable. Actually, stopping them down will help a lot, but the purple color will still accumulate on an exposure. I'm using the Orion 80ED now, and it's just superb. For the price, it can't be beat. And, it's an excellent scope for astronomy too. It holds up really well even at over 200X. With the exception of the Orion 80ED, I haven't found any of the "ED's" to be much better than a simple achromat. The 80ED is a true apochromat. If you can make the jump, you'll really appreciate an apochromat both for photography and astronomy.
I used the little 80 f/5 for years, and it was fun as long as you stay under 15X, which is usually not a problem for photography through the telescope. You can do a lot worse for the modest price they cost. -Kurt Horsley

Red-tailed hawk?

Posted By Kurt Horsley
You are correct Louis. It is a red-tailed hawk. Nice picture too. Sometimes back lighting just can't be avoided. But it doesn't detract too much from a good shot like this one. -Kurt Horsley
