I have owned an Astrscan for over 30 years. It has flown with me to many vacation destinations in an airliner overhead compartment. I truly have an emotional attachment to it.
But, as has been pointed out by some previous posters, do no expect much from planets. My husband and I recently took the Cherry Bomb apart to clean and collimate it. This was an ordeal.
Expand your deep sky object list though. Yesterday, one of my observing friends said he saw all parts of the Veil Nebula near Cygnus in one eyepiece view with an Astroscan. This was in south no-light-pollution Texas, but still.
Regarding the 28mm RKE: guard it with your life! An awesome eyepiece.
Thank you for some insight into your Cherry Bomb, as you call it! The Astroscan really is a unique scope. When I first saw it in person, I thought how wild the shape was, that it just wobbles back and forth on the stand like a floating ball. It doesn't tip over and is very user friendly, honestly much bigger than I thought it would be as well! That's amazing your friend was able to see the Veil Nebula! That must have taken some skill actually finding it on the Astroscan, even in the dark skies. I can barely see the Orion Nebula and Andromeda Galaxy from where I am. They both appear as a very slight, dim cloud, but wow what an amazing sight! My wife and I camped in the Utah wilderness last year and I would have loved to have my Astroscan at that time. I will never get rid of these RKE eyepieces, the 28mm is perfect for the Astroscan too. Thank you again!
