I was numb like when you injure yourself bad.

I did get some daytime images afterwards and it seems like it's OK.

Rain in forcast around here from now until the end of time, so I decided to take it apart.

It cracked two of the three oak blocks I used to mount the lens cell. It scraped the finish off of the front of the lens cell in a couple of places.

It craked my wooden 7" OD / 5" ID step down ring I had made. So I am going to make another.


On the plus side, I leanred a few things building the step down the first time and can do it better this time around, making it stronger, giving it even firther collimate capabilities, and maybe, just maybe a little better looking.

exact same thing this morning, by the time I figured out focus and got it on some stars, my sucker hole was gone.


UUHHGGG


You know what? I never drop'd a scope in my life til yesterday. 1st time mounting it on the Atlas, boom, hard on the concrete. UUHHGGG

I was able to get some sharp daytime images afterwards though. I feel like such a dummy right now.

The bulk of the scope makes it hard to get the dove tail seated squarely, and it tumbled right out of my hands.





Are you tellin me you dropped your new 8".....On the cement?

Just another reason why I never remove my 6"f/15 from its mount. Why?

It takes three people to mount my OTA.
At star parties that I have to go to, I leave both guide scopes on the OTA, and the 200mm wide field cameras attachment. HUfffff.

I only pray all is well. With both, you and the scope..

yes, hard right on the concrete. UUHHGG


Seems to have survived.


I was doing it by myself, which it is do-able. But I cannot use the same technique used on my 6"'rs.

It is just difficult to get those long tubes lined up for the dovetail. I though I had it, then it tumbled out of my hands. The scope is slated for permanent installation thank goodness.

Good, very good.

I guess the real good thing that came from all this(I'm the optimist), is that you can make it better, with the knowledge you aquired the first time round.....Even better.

It payed to dig in, cause you found some serious damage with the wood parts......

That can be fixed. A fractured lens is all together another issue......
