HiPlease share your opinion on something. I have a 90 x 1000 mm EQ Celestron refractor and I am thinking of maximizing its power. The question is can I use a 5 x Barlow with a 2.5 mm eyepiece with this I know about the issues with high magnifications and I will also buy a tracking motor to compensate for the rotation. Please tell me if this is technically possible and if I can still focus an object using these. Thank you in advance
