I have the same HEQ5Pro mount and when polar aligned really good I can get a 4 to 5 minute with my Pentax KX and 200 mm lens fairly easily. I still going through the insane amount of garbage you have to go thru using a 8in Meade SCT on this mount, and I did finally have to get a small guide camera so I could use sharp cap to polar align well as the polar scope retical was out of whack real bad with my mount. Don't give up, as soon as you get your first quality photo that you like it makes it all worth while. After years I just got a picture of the Andromeda galaxy that I was happy with and I am struggling to repeat it. I have used a small Evostar refractor to get this pic. I am not good using photo enhancements yet such as Photo Shop to really pick put the dark space background and star colors, that's going to cost the price of a used Televue eyepiece and I am not ready for that. BUt the mount seemed to track well unguided for 2 minutes easy and this was about 7 frames, not many at all.Andromeda test 2 sequator enhanced.psdAndromeda test 2 sequator enhanced.psdAndromeda test 2 sequator enhanced.psdAndromeda test 2 sequator enhanced.psdAndromeda test 2 sequator enhanced.psd
