ArgoNavis placement on a Big Dob
I’ve been asked about this a few times, so I thought I’d open a topic to see if anyone else has views/experience in the matter.
I recon:
When using a big Dob with just ArgoNavis, Mount it up top just where you need it to be. It is really good for fine tuning/locating objects by hand, and when you are cruising around a constellation, the object will never be too far away from the starting position so it’s quite possible to see a few targets with out moving the ladder – just by leaning over a bit (but not too far).
However, if you have ServoCAT (or plan to have it) it’s a different matter.
The ArgoNavis really should be mounted on a stalk for one main reason: The torque in ServoCAT is amazing. It slews a monster scope faster and more quietly than your Meade/Celestron would do. The system used in the 18” is exactly the same as used in the 30”. You (or worse, a guest) don’t want to be teetering up a ladder when you press the Goto button on a big slew in your direction ‘nuff said!!
What do you think?
I've put some before and after photos for consideration - the ServoCAT wireless handpad now lives where the AN did.
