Hello, does anyone know if my imaging train looks correct, and if it does, why am i still getting these coma errors?
Could it be incorrect backfocus? Searching the internet makes me think my dslr is 44mm, adding the t ring (even tried a 1mm spacer too) gets me to the required 55mm (assuming that's correct)
I have no idea how to solve this and i feel like I'm just throwing money down the drain fighting this in vien. Help would be much appreciated.

Reducer rotator for 72ed (needs this for extra distance to achieve focus, the reducer and adapter alone doesn't allow for enough outwards travel)

Is anyone here using the TS Photon 6" F4 newtonian? I'm about to purchase it but I have some doubts and questions:
1- Does it hold collimation well, at least in a single session?
2- Is it impossible to balance in DEC due to its small dovetail or is it possible but harder?
3- Is the focuser rigid enough or does it introduce tilt?
4- Will collimating it be a nightmare?
5- I'm really picky when it comes to coma, should I expect some coma on edges even while using the Skywatcher Aplanatic F4 CC?
6- All in all, do you advice me to buy it or have some other option in the same price range.
