Thanks for the reply, does the image quality depend on if I put the ADC before or after the barlow?

Hello, I was looking to buy the 10in skywatcher synscan dobsonian to pair with my ZWOASI 120MC-S. I have decided to buy the ZWO ADC and the Celestron X-cel 3x barlow for this dob and camera. The telescope itself has a focal length of 1200mm but with the barlow will have 3600mm. I wanted to know how much focal length it would increase by, if I then added the ADC. Is there any easy way to calculate this, and is the resulting focal length too much or too less to get the best results while imaging? Thanks!

I have a eq-3 bresser mount, max payload of 13 kgs

Hello, I got a 102/1000mm refractor about 2 years ago and I would like goto for it. Is OnStep and its kits from George a good option? and if yes which kit? Thanks
