Description

Version A : Askar 130PHQ, ASI6200MM on AM5
Version B : Askar 80PHQx0.76, ASI2600MM on HAE43
Filter : both Antlia V-Pro LRGB

(Ver.B was integrated 2x Drizzle then StarAlignment to Ver.A)

I wanted to compare 80PHQ and 130PHQ (both really I love) at same time, same guiding accuracy.
130PHQ shows clearly better resolution at surrounding very small stars.

Ver.A Result L FWHM=3.28px(2.54arcsec)
Ver.B Result L FWHM=4.9px(3.8arcsec)
