which barlow lens for planetery imaging?
i have just ordered a dbk21 colour camera for my 8" mak/cass (f/l 2500mm) to do some planetery imaging. what setup should i use to project the image onto the chip?
i have been told i can use a barlow lens(2x or 3x). if so which one is better and why.
or i would need to buy an eyepiece adaptor. the thing is that my best eyepiece meade 5000 series 14mm i think will be too big to fit, so i would need to use my 10mm generic plossl which is nowhere near as clear as my meade 14mm. i also have a meade 5000 9mm, but conditions are usually not quite good enough to get a really clear image.
so which is the better option for imaging? adaptor or barlow?
thanks for any help.
