Re: [ATM] Purpose of baffles/shrouds

["Peter" <peter@kitgear.com>]

Tom,

Good idea regarding the pics.

I just uploaded two pics which I think will describe the concept. The
focuser tube will be at least 9" long with 2 movable baffles to allow me to
optimize contrast. It will be similar to the same way an SCT looks upwards
toward the secondary.

Please let me know what you think?

Peter

A picture's worth a thousand words.  Can you post a simple layout
diagram...kind of like what James Lerch just did?

Thanks in advance.
