The Questar definitely held it's own against the C-6 this morning. The seeing looked average-to-good so after I took a few captures with the Questar I continued with the C-6 for the rest of the morning. Now I wish I would have kept imaging with the Q too. I will be out there early for the transit. The shadow should pass just north of the GRS and should be a neat image. I think that happens around 0130 AM EDT.
Anyway, I like this comparison and it speaks well for the Questar because the Celestron C-6 is a really good scope! Both were imaged at f/15. The C-6 image was downsized to match the Questar's scale. The only thing that concerned me was the obvious grid pattern showing up on the Questar image. I capture at RAW16, so maybe that's playing into it.
