So just a word of warning - if you expect to spend $7K on an APO, be prepared to spend $5 - $10K on a mount and $2K - $10K on a CCD, it all depends on what your are planning to do with your gear (i.e. how dim will be the targets you wish to image). This will determine the precision and capabilities of the mount and possibly the imaging camera you will require. Then there is the matter of guiding - requiring mounting for a side by side or piggy backed second OTA and camera - or an On or Off axis guider plus camera. Then there is control and image acquisition and processing software, precision focusers and other equipment.

At the high end - life ain't cheap!
