Sure, it's possible. Depending on your target. A black hole against a black target is hard to see. I go by the local high school at the end of the season and get as many of their schedule posters as I can. That shiny paper (the back is pure white) with a small aiming dot works great. I can get four or five aiming dots on that poster, and when I look at it through the scope, it's easy to see.
Believe it or not, my go-to spotting scope (for 100-200 yards) is the
Bushnell Sportview 20X60. Yeah, yeah, I know, cheap Bushnell, but when I go to the range, it's normally the Bushnell that gets the nod. My wife bought it for me several years ago as a Christmas present, and I use it constantly.
