[Aavso-photometry] DSI Pro

[Jeff Hopkins]

Several people have asked me questions about the DSI Pro.

If you purchase one, there are two versions the DSI (Color) and DSI 
Pro (Monochrome). There are also two new ones the DSI II (Color) and 
DSI II Pro (Monochrome). For photometry get the DSI Pro.

Do not get the filters unless you want to take color pictures. To use 
the DSI Pro for photometry I suggest replacing the face plate with a 
low profile one from ScopeStuff. This gets rid of the large holes 
where the filter slide goes. At the same time you can get a dark 
slide that makes taking darks easier. Look at the shutter item and 
you can order both the low profile face plate and shutter for a 
reduced price.

For BVRI photometry the ATIK filter wheel works well (also available 
from ScopeStuff).
