Quote:This is off-topic at this point, I think, but my experience was, I'd do a polar alignment with the polar scope and be very close. I'd then do an ASPA and be a little closer or a little further, depending. Either way, I inevitably had to do a drift alignment.

Quote:I'm not sure that a full 2+4 alignment is needed but if you do a 2* alignment use a star on the same side of the meridian as the alignment stars.

Quote:Does anyone know if the AVX is designed to accept a polar scope, perhaps a CG-5 polar scope ?
Money can't buy happiness, but it sure makes living with misery a lot easier!
Quote:If you just do a 2-star alignment, it will use the calibration info from the previous session - but that info will be old and possibly stale. A key issue is if this mount has index switches like a cge, or just index marks. In order for the calibration to be reusable, the index marks would need to be set very accurately.

Quote:The dec ofset is to get the initial stars closer. Once the model is mazde it has no relevance. The calibration (which is actually just one as the 4 are averaged together) will make a big difference as the mount WILL have cone error.
Quote:The marks give a starting position. BUT...it doesn't even matter what that position is _as long as you use it every time_ you can make your marks wherever you want them.

Quote:When you crank on the knobs to adjust for the ASPA the mount can't possibly know how many turns of which axis you made so how could the alignment still be valid?
