well ive just finished the images so you all can see what the fuss is about .
the more i use this lens the more i love it the bigma has been made redundent to walk around lens.
skywatcher ed80/600 f7.5 pro O.T.A
this image shows it all connected together what a beast
the focuser is all the way out which is at its C.F.D with the adapter of 21ft.
also notice the grayford focuser this is done by friction and not the wobbly (rack and pinion)
the rear end and i dont quit now how apature's work on scope but i supose the f/no. comes from 80 in 600= 7.5 but the apature is bigger than that ?
the important bit doublet ed glass flp53 and this makes a lot of differance
( i was going to get the f5 150/750 refractor which cames with motor triopd but i stoped my self no ed glass.)
are the bit that makes it all work camera adapter also nown as prime focus
tube etc.
note on this image far right eos m42 adapter then a little t-monunt then tube and finaly the direct slr mount which came with the scope.
are you still with me good next.
i dont now if i've done this next test right but it show the D.O.F this was 600mm C.F.D 21ft on the ruler the 20cm make is in focus so not a lot realy.
how sharp i here you say well this next image will answer that i can say nothing ells on the matter.
and finaly what's it all about to get image of birds or other wildlife .
this image was with the 2xtc and 50mm extention tube + camera adapter C.F.D about 10ft.
all this for £295.
