Bravo chap!! 
Ps - put the 12" up on the PME, sell the 10" RCOS.. then your costs are not so extreme, and the results would be similar if not better given local sky conditions.... Just a thought..  |
Thanks Alex
Actually, im kidding, ive seen some very good close ups on refractors, and given the apature, must be much harder
Yes, ive considered putting the 12" up, but setting up everything again (image train adaptor hell, pointing map, FOV indicator, focus max etc) makes it just too hard on a whim, and the RCOS is soo stable.
The last time I tried the Meade, there was something very wrong with images (with the long image train, same as the RC plus a focuser, stupid long), havent worked that out yet, could be way past the back focus, whatever it is on an SCT, cant find out. Ive seen an image train that long on Astro anarcys site, but with a FR, seemed to be fine, although counter intuative (doesnt a FR reduce back focus?). Fitting the FR is more adaptor hell, its starting to get unwieldly and unstable
(the ST10/filter is way heavier than a QHY).
mmm, come to think of it, I must ask Stuart how he does it.
