Time for a Review - Scope for later years.
One thing that I have learned through this opposition season is that my one good eye is not as good as it used to be. I have macular degeneration in my right eye, which yields a blurred grey distorted spot in my central vision, and it will not get better. This leaves me with my left eye for all things Astro, and it seems to be letting me down abit lately. It has floaters, and this can be distracting when looking through an EP. I find especially higher powered EPs a problem, I need long eye relief now.
So among my collection (which used to be much larger) I have been using my iStar 127mm f12 R30 refractor much more than my 8" Cassegrain, and 8" Newt; and I cannot really put my finger on why I prefer the iStar, maybe it's just easier (no collimation, no coma) and no stool required as with the Newt.. I should point out, I am visual only now, image processing is too hard with two eyes of different focal lengths (yeah, macular degeneration alters focal length).
I plan to reduce / revamp the collection to scopes that are easy to use, (no SCTs or other floppy mirror systems), do not require exotic collimation rituals, and are reasonably light to carry. I am giving up on long focal length, because it requires good eyes imho, and it usually means reduced brightness I find. I hate the idea of giving up the iStar, mostly because I built it around the very nice objective provided by Ales before they moved to the US. But the iStar is probably too long, for the years ahead. A nice f7 or f8 refractor might be a good compromise, maybe a Doublet (to keep the weight down) but with good apeture (150mm?).
Any suggestions or advice regarding re-equipping? Have you done this sort of thing?
PS, I work out of my observatory, so leaving something setup is no problem.
