I heard there are back focus issues when imaging with a PST. Stacking the SM40 onto the PST may result in a very dark image. It means taking pictures will also be a challenge.

No, it's not easy. But, Yes, it's worth it.

As I mentioned before the focal point of PST is just a few millimeters above the 1.25" barrel, so be prepared for huge focus problems.

Photography with PST can only be done with eyepiece projection, or use low profile adapter for Toucam or use a barlow to push the focal point out.

I use the eyepiece projection method with the Scopetronix Digi-T. No problems so far...
