Hello experts!
I already own and old SM90 but am tempted to purchase the following package (used, about $3,000):
- AR127 mm
- Coronado SM90 II (front etalon)
- Blocking Filter BF30
Is this a good combination/price? I was thinking about buying a new SM90 front etalon instead to DS, however, the price for the etalon alone is about $3,000. I am mainly interested in visual (prominences, filaments).
Thanks!
Frank

Seems a good price. You would have 2 SM90 etalons then so you could double stack?

Thank you Mark! That's what I thought, if I am not pleased with the views, I'll still be able to DS my SM90.
