It's cheaper than a lodestar x2, has a much bigger FOV and technically is a hair ahead in QE as well. Why buy a lodestar?
Lodestar sensor is 6.45 x 4.75mm, 174MM is ~11.34 x ~7.12mm. ASI120mm is only 4.8mm x 3.6mm.
I'm wanting a high QE sensor that has the biggest chip I can get, to increase the odds of finding a guide star without rotating my OAG.
