Messing with 3X Teleconverter/DSLR

Hi all.  For a couple years now I have been happily shooting the moon with my A77ii + Minolta 400/4.5 + 2X TC.    I recently picked up a rather odd duck - a 3X Kenko TC.   Still have not had a great seeing night - but I am satisfied it will be used instead of 2X - it also opens up the possibility of stacking it with my 1.4X (my 1.4 + 2X cannot be stacked with each other) and gives me enough reach that I can compare my 400/4.5 with my 300/2.8. 

Jury still out pending a great seeing night!   

Here are two stacked photos from last night - first with 300/2.8 @1260mm and second with 400/4.5 @ 1680mm.  (3X + 1.4X = 4.2X magnification)

Files open to 100% size.

 

Very best regards

 

Mike
