Dear friends:
Looking for recomendation!
I do have a LX90 8" and do like it very much, every time I have had opportunity for using it I had enjoy it very much.
I been lately in the photoastronomy and looking in to it I would like to pigy back a Series 5000 127 apochromatic telescope with a Canon 30D camera.
My question are;
1.- would the LX90 8" be able to handle the series 5000/Camera in the back, if not what can I do or how big of an apochromatic telescope it can handle?
2.- what kind of precautions should I need to have in mind. ( I understand that a well balance needs to be done)
3.- Is there any specific recomendation from someone else lessons learn?

Thanks to all in advance  for their attention and comments back.

For the weight of the 127 I think it will be to much for the 8 inch.
The 80 mm APO should work well on it and should balance out well.
I would use the Losmandy rail and rings to be sure you get a good stable mounting.
Just be sute to get a good balance and I think you will be ok.

Mark thanks for your comment.
How big do you think I can go, you say 80 will be OK can I go 90 or even 100?
Yes I understand that balance will be critical, and I had thought in that, so what ever final desition I make I will take your comment about balance.

Gracias
Miguel.

I think 80 mm is as big as you can go but you may be able to go a tad bigger.
From what people have told me they wouldnt add to much more to it.
