Dear Yurij,
Here are the main characteristics of the 1.54m telescope in Bosque
Alegre.
The telescope has authomated motion from an office close to the telescope.
There are two focus: Newtonean f/5 with scale 26.78 "/mm
and a modified Cassegrain, Nasmyth f/19 with scale 6.7 "/mm
We have a multifunction spectrograph (actually of russian origin!)
which can be used to obtain direct images althoguh there is a
demagnification of 3. The FOV is 5.7 x 6.7 arc min
with a scale escale 19,87/mm , or 0,38 per pixel
So, the equivalent focal distance of the system (telescope + focal
reducer) is 10.38 m
Four filters are available (3 inch x 3 inch size). B, V, R, I
Best regards,
Diego
