Looking for thoughts on ASkar 107 phq. That or Skywatcher esprit 100 edx. want to keep my zwo am3
Get the counterweight for your AM3. Cheap and the AM3 will be able to handle the 107PHQ in my opinion. You may give up a little in guiding, should still be able to guide at .65 to .80. I use the AM3 with the 65PHQ with no counterweight and my 103apo with the counterweight, even though not required for the weight of the 103. I guide between .45 and .68 normally with the 103/AM3 combo. Sure, it would be better to get an AM5 but you can do that later if the AM3 and counterweight is not to your liking.
CS,
