Wondered what peoples thoughts were on these?
Do you have them and use them, and when do you use them? Aligning, guiding for photography etc??
What brand and size?
Should they be a necessary EP in your case (not for Dobs though)?
I have a new little goto scope (very cute) to play with, and was tempted to get one, to assist in guiding for (basic) astrophotgraphy.
