Stepping back to the Toucam with an Achromat

Last night was an Astronomers Dream. Perfect sky!

I wanted to compare the new DSI with the old Toucam so I spent a bit of time with each.

As hard as I tried, and as crisp as I could focus, somehow the El-Cheapo webcam Toucam still gives better stars and detail than the DSI.

Whereas, the DSI captures images in a far shorter time due to better sensitivity.

Not to be done with the experimenting, I also took the Toucam out of the ED80 and put it into the 120mm Achro guidescope to see how the Achro responds.
I found that due to the larger apature, the 120mm allowed me to get detail in a much shorter time which, in turn, reduced the amount of Amp Glow I normally battle with.

Below are 2 images taken with the Modified Toucam thru the Saxon 120mm f5 Achro, Astronomiks IR/UV filter and 0.6x FR.

Neither of them are fantastic, but it was fun experimenting

2. 47Tuc
