I have heard William Optics FLT 91 Fluorostar is one of the best optic refractors of its league.
Can I use a 2.5x Televue Powermate (one of the best premium extenders) on William Optics FLT 91 Fluorostar (or say WO FLT 132), and use it to capture galaxies?
Plan to use it with ZWO ASI 2600mm camera.
I know it becomes slow with f/13 or so, but if I expose the subs to say 10 mins each (I have iOptron CEM70 mount), I can take care of the needed light.
Question is will it work optically well to capture galaxies with good clarity?
