Discovered What Was Wrong With All My Telescopes
I bought three Maks in the last five years, and their images on planets weren't quite as crisp as what I expected. My SCT wasn't that crisp either. Neither were my little refractors. There always seemed to be a soft spot with some slight glare to the side of the planet - but I was really pushing them at high power.
So I kept checking for dirt of the objectives, and on the various diagonals - including a TeleVue one.
Thus earlier this year, I mounted my 4" Vixen APO, which I know is my best telescope and - I got the same result. Maybe, I surmised, I just have lousy atmopheric conditions in this new place I've moved into.
But I found out the cause of all this poor performance the other day. I went for an eye test, and I have moderate cataracts.
Finally, the mystery was solved - how about that?
Cheers,
Renato
