The internal stacking module dropped the bandpass below 0.5 Angstroms just as promised, and seeing surface granulation pop with that clarity is incredible. I spent a whole afternoon tweaking the pressure tuner to chase Doppler shifts on a prominence.

The pressure tuner is a game changer for dialing in those really subtle Doppler shifts. Paired with the lowered bandpass on my 130mm, the surface detail is just incredible now.

Finally got it installed on my Lunt 152, and the pressure tuner makes dialing in Doppler shifts incredibly smooth. The difference in surface detail between single and double stack is honestly night and day.
