hello

twice a year my telescope has a right to clean early October that took place ...

Here are some images of the operation that shows you the opening double octagon of the primary support, good practice  for this operation or exit the mirror easily without too much risk.

It takes around 4 liters of mixture to fill the mirror.

Clear sky.

Hello

Thanks Paul for the laughter.

625 mm is the optic diameter the blank is 630mm for 55mm tickness and weight 36 kg.

If you want what this telescope is capable to do it's here :

I'll bite. How did you get to 625mm?

If you say PM'ing Luc, I shall be most disappointed.

As a French Canadian I had the advantage of being able to read the first caption :)
