Re: Anybody using MFT bodies for astrophotography?

Big thx for all the info. So ive been doing much reading and i think a refractor is what i will get the most out of. One last question, if i get a faster shorter model like a 90/500, wont using a 2x barlow essentially crop the center 40% or so, mostly cutting out the outer field curvature?

In a way that seems effectively what using a smaller sensor does no? And its funny you mention that Panny feature, i was just talking to my son about video stacking last night. GX7 video is pretty crisp for only 1080p and ETC gives another whopping 2.6 crop.

So if my above barlow assumption is correct, should i use a barlow on a wider scope or just get a longer fl and eliminate extra glass? If i know i want the reach anyway the longer seems best.

I read the words
'You form a line to formalize the former lies.'
And I finally saw the truth
Something so profound and now it's sitting there
Surrounded by the garbage and the stains
Another victim of the refuse
Now I've been saying this for years
But you don't comprehend it
I fight hell and I fight fear
Because I understand it
Androgyny and insults
You try so hard to be difficult
You want to win the war?
Know what you're fighting for"
