DSI Pro image size

[middy]

The specs for the DSI Pro state an image size of 510 x 492.

Using Envisage, if I save the individual images they are 648 x 489.

The dark frame produced by Envisage is 508 x 489, which makes it difficult to use an external program to apply darks to the individual frames.

Does anyone know what is going on here?

I found the answer. It is all to do with the DSI Pro having non-square pixels and the software applying a multiplication factor to get the correct aspect ratio.

Aye, it's a pain isn't it
