This mount seems to be well suited to my needs (right payload for astrophotography with my 6" Newton telescope, a DSLR and a guider) but I'm not sure I understand everything about it.
I read here and there that it was recently updated. When was it and what changed? I'm tempted to buy it second-hand but I would not like to miss a useful feature.
If I buy it second-hand what are the problems I should look for?
Apparently there are 2 tripods available with it but what are the pros and cons of each?
Thank you for your advice.
