Hi, I was reading the book "The Caldwell Objects" by Stephen James O'Meara cause I was interested in his observations of planetary nebulae. He wa saying instead of putting in a high magnification eyepiece, use a moderate power eyepiece with a 2X barlow. You essentially get the same magnification with higher contrast. He said to try it with the barlow then switch back to the higher magnification eyepiece to see if there is a difference. I was thinking of getting my refractor out tomorrow night to see some fall-winter objects and will take my TeleVue 2X barlow with me. Digital Setting Circles are working great since I tightened the nut on the RA encoder. I also checked out a good observing book at the local library. It is called "1001 Celestial Wonders to See Before You Die" It has some great photographs of deep sky objects. Hopefully the weather should clear up soon. Clear skies, Debbie
