SV555 Deep Sky Photography Kit
The main advantage of having an OAG is that it uses the same optical path as your primary imaging camera. This avoids any issue with differential flexure that can occur when using a separate guide scope on top of your main telescope.
From precise tracking to a stable power hub, one complete kit lets you effortlessly capture the dazzling depths of space.

I have now actually been able to test the telescope! I am very happy with it! It is, as always, got that feeling of being built well. This is the telescope I should have always got in the first place. The stars look good, I have a slightly conical shape but I would pin this down to my camera or adapter rather than the telescope, probably sensor tilt or something along those lines. The filter drawer is a must but takes up a fair amount of the backfocus and the focus distance is really short, but at the end of the day it is a cheap telescope. I only got an hour on Orion and horsehead, and then rosette another hour, it’s fast optics got me quite a lot of data in that short time with narrowband. I am excited to get 10 or so hours on the Polaris IFN! It has brought the excitement back because it’s light, quick to setup and I can start imaging as soon as possible!
