In this video I would like to introduce you to the Telrad finder scope. This is a finder scope that you can attach to the telescope.I personally can recommend this finder #astrophotography
You might want to include the "pattern making" method for finding deep-sky objects that the Telrad's 3-ringed reticle is designed for. You might also want to include the use of Right-Angle Correct-image (RACI) finderscopes, as they can help greatly in relieving neck strain when looking through the finder.
