Hello, I have been using medium to lower focal lengths for a few years and wanted to get into the realm of high focal lengths for deep sky. I know that its usually more expensive then high focal length planetary, but I am willing to spend a few thous...
APOD features deep sky astronomy content; high focal length telescopes useful for similar imaging.
As noted elsewhere, I’m in the early stages of trying to make the transition from what has mostly been “electronically assisted astronomy” to producing some nice images. So I present last night’s effort here for input, with particular regard to acqui...
APOD showcases deep sky objects like M 63; relevant to transitioning deep sky imager.
