I have really gained an interest in lunar observing. In fact I am working through a training course on observing at the present time.  I need to get a barlow lense to use with my LPI.  Any comments or suggestions on the magnification?  Furthermore, if you have used a barlow do you find it dificult to image with the additional magnification?

Thanks

A barlow is a good addition for high magnification imaging.
It can be harder to get your object centered on the chip but is very possible.
you can use a 2x,3 x or 5x barlow but remember seeing conditions and transparency plays a big roll in high magnification imaging.
Meade offers several options in barlows and should have 1 to suit your needs.

I often use a 2x barlow for planetary imaging. It really helps to get the image scale you need to bring out details. I have tried stacking 2-2x barlows with some success.

I would suggest you get the highest quality barlow you can get for your budget. You might start with a 2x or 3x. At 4x I find that my polar alignment needs to be near perfect or else I start to see lots of image shift. I also find that focusing at 4x is really tricky.

I use the Meade 3x with great success.  I think you will find it very useful.
