That’s interesting to hear! I’d assumed the EQ3 was quite a popular wide-field imaging mount.
If I recall correctly, Ian Sharp uses an NEQ6 as a slightly-overkill DSLR-mount-with-autoguider, and a few people seem to use the HEQ5?
Not seem too many people use an EQ3, but then I guess it limits your options if you want something you can also put a telescope on. And I have no idea how stable it is…
