The differences in telescope performance can be quite subtle. Using an APS-C DSLR, you may not ever notice a difference. The same goes for a KAF8300 sensor which doesn’t have a high blue QE. If you were using a QHY183 with its minuscule pixels and high blue QE, this is where the TSA will likely begin to shine.
