Nope Paul, they are too expensive. This was just a trial after the idea of using the Toucams original IR lens plopped into the adaptor was posted in here.

I used an ED80 and .65 focal Reducer
Individually focused? I don't get the question unless you mean did I re-focus on each object. No I didn't, focus was perfect on each one so I didn't have to re-focus. I always check focus on each object. The only time I had to re-focus was after taking the IR filter out.
Also, none of the images above have been processed yet. Just raw data stacked. I usually clean the stars up during processing.
