Focal Reducers
Hi everyone,
I own a celestron cpc 800 telescope which is f/10. I also own a focal reducer which reduces the scope to f/6.3. I was wondering if there are any other focal reducers available for reducing my focal length further say to f/4.
Also has anyone thought of putting focal reducers in series? I don't expect it to work and I don't want to buy multiple reducers to experiment to see what happens but interesting to know if anyone would know the outcome of doing this.
Anyway would be interested to find out about the above.
Regards,
Tom
