SCT Reversed and Inverted, So What About the Star Chart

Hi,

I have a question that may be embarrassing, but here goes any way.  First of all I have a new mount, camera, filter wheel and optical tube ordered (3 month wait...ugh). I am trying to plan ahead and was looking at the back focus requirements for the new camera, etc. etc.  The new telescope is an Celestron EdgeHD SCT, I mainly do photometry, the diagrams for the new camera were showing the camera attached straight through the telescope for showing the back focus distance.  That makes the image reversed and inverted. SO that got me to thinking...

I have always used the diagonal with my current camera (very small and light) so that the images are only reversed. To be honest about it I never really thought about before, but...Is that the right way? Is there a better way?  My concern is the new camera and filter wheel will be too heavy for this configuration. Is there a way to generate a star chart that is reversed AND inverted so I can easily match it to the image taken WITHOUT the diagonal?

generate a star chart that is reversed ....

Darrell,

Look carefully at the various options VSP present you when ordering a star chart, you can have them any way you like.

Also, you can use the acquisition software ( well, most of them allows that) to present the pictures anyway you like.

Good luck,

Damien
