My 80ED arrived!
Posted 05 November 2003 - 10:44 PM
The appearance is almost identical to my 100mm SkyView Pro refractor. The 100's tube rings fit the 80 perfectly, so I was able to pop the ED on my SkyView Pro mount. The dew shield fits around the objective perfectly; the 100's dew shield never quite made it all the way against the lens cell. But anyway, on to the important stuff!
I popped in my little collimation eyepiece, and as expected, the ED was out of collimation. (If you don't know by now, this scope doesn't have an adjustable lens cell.) I simply loosened the 3 screws (very slightly) attaching the focuser to the tube, wiggled the focuser until the collimation was right, and re-tightened the screws. I didn't have to use shims or anything. When I looked down the tube from the objective end just to double-check, everything appeared concentric.
Once it got dark, I brought everything outside. It's remarkable that the sky was mostly clear! There were a few clouds, but nothing that interfered with observing. I looked at Mars, and MAN was the seeing poor!! After the scope cooled down a bit & the seeing improved, I began checking out Mars with different magnifications. First of all, I didn't see a trace of chromatic aberration. I was shocked at the difference between what I saw & what I had been seeing through the 100mm achro! My top magnification is 200x; I used a University Optics 6mm Ortho with a Celestron Ultima Barlow. Mars appeared a whole lot sharper than it had through the 100mm at 200x.
I also took a look at Vega. At high powers, I did see a very, very slight trace of false color. But it certainly wasn't anything to complain about.
The Moon looked spectacular! Again, absolutely no Hendrix effect (purple haze) around it.
The Double-Double split up very cleanly. I could even make out all 4 stars at around 54x. Albireo looked beautiful, and so did Gamma Andromedae.
I glanced at the Double Cluster, but the Moon was way too bright to really see much. I also took a quick peek at the Ring Nebula. I was surprised at how well I could see it, considering I was using an 80mm instrument under a nearly full Moon! But it was pretty faint. I can't wait to see these DSOs when the Moon isn't around.
Finally, I LOVE the Crayford focuser! This thing is so smooth it seems like you could almost breathe on it to adjust the focus.
I give this little scope an A+. I can't wait to see Saturn & Jupiter through it!

My ED80 arrived about three weeks ago. It was purchased second hand but unused from a gentleman in Minnesota who had ordered it through Company Seven.
This morning, arising at 4AM, was the first time I had the combination of clear sky and time to leisurely use the scope. What follows is the first journal entry I have written-up since obtaining this scope. To sum up the entry, the performance of this scope is very aesthetically pleasing.
11/8/03 4-6AM EST;
Saturn on a slightly unsteady night readily shows cassini at 85X and, in moments of steadiness, show a beautiful view at 150X (48X) per inch. Even at nearly 100X per inch, in moments of steadiness, the view was good; no bleeding of detail, no haze in the anzae or cassini. No loss of detail, just more spread out and dimmer. No chromatic aberration.
Jupiter shows 2 belts, the GRS, darkened poles, hints of detail within the 2 belts. [This, only 30 to 40 degrees above the horizon and close enough to the roof of the house to be getting some thermal disturbance this 35 degree morning.] No chromatic aberration.
At 85X castor is easy but not pretty this evening. Earlier, immediately upon bringing the scope out of the house and looking at Polaris at 150X, despite a 30 degree differential (drop) in temperature, Polaris showed an airy disk, diffraction ring and hazy fuzz. Thirty minutes later, it showed only the disk and ring; no haze, no fuzz.
Eyepieces used are UO orthos (12.5, 7 and 4mm).
By the way, the jinx is broken. When the scope arrived it was a clear sky.

I still haven't been able to push the power up to 200x yet on planets; it gets kind of hard to focus. I hope that's just due to seeing being bad. I get a slightly clearer image at 187.6x, and at 150x, everything is nice & sharp.
I wish the Moon would go away so I can try some deep space objects!

I sent you some messages - did you get them because nothing appears in my sent items folder? I might have done it wrong.

I guess I should mention that when I cranked up to 200x the first time, it was on Mars. Due to Mars's shrinking size & the fact that my scope may have not had sufficient time to cool down, I'm thinking that's why it appeared a little "mushy" at 200x. I glanced at Saturn at 200x the other night, but it was pretty low in the sky.
It's a beautiful, clear night, so I'm gonna be going outside soon! I'll see what else this little scope can do for me. This time I'll let the scope sit for a while & cool down.

Never mind...I waited too long!! @#$%^&* clouds!!
I think my last 3 weekends have been spoiled by weather!!

Saturn was near the zenith and the seeing was excellent, so it really blew my socks off! I saw at least 2 bands on the planet, and maybe some subtle shading in different areas. The rings were magnificent. The Cassini Division was so sharp & easy to see. I could also see differences in shading around the rings.
Jupiter was just rising above my neighbor's house. Once it got a little higher & cleared all the really turbulent air, I watched Callisto's shadow move across the planet. There were several cloud bands visible on Jupiter. Also, there was no sign of chromatic aberration around it.
I was able to crank the power up to 200x; both planets (especially Saturn, since it was so high) remained sharp at this power. (200x is as high as I can go; I used a 6mm UO HD Orthoscopic with a Celestron Ultima Barlow.)
I also glimpsed a 5th star in the Trapezium! I think this is the first time I've been able to see it with 100% certainty. The Orion Nebula itself, even with the gibbous moon nearby, was quite a sight to see.
This scope is wonderful! I can't say enough about it!
(By the way, when I said, "I can see a 1st/2nd magnitude star with an airy disk around it" in the post a couple of spots above, I meant diffraction ring! I just realized my error! :o )

Everybody has been buzzing about this scope. I am happy to read such a great report on it.

I checked out the site and see that they are in Germany. They offer a mid sized inexpensive refractor as well as what looks like a 5" mak. I think the refractor was reviewed by one of the members. Hope this helps.

I figured out the total cost of my setup, and the number approaches $1900!!
Mistake #1) you know the total cost of your setup (new).
Mistake #1a) you know the total cost of your setup (used).
Mistake #2) the wife knows the total cost of your setup (new).
Mistake #2a) the wife knows the total cost of your setup (used).
Just wait Bill, just wait.
