Thank you for the tips I will try these tonight if it is a clear night
.
I always do a Solar System align because it is easier and quicker than finding stars but I will try a 2/3 star alignment. Once I can get the Moon to lock on and stay with it then I should be able to capture some decent video. If you touch the OTA it does move a bit so even though it is securely tightened underneath the mount still moves a tiny bit.
Mate the MBPR is fantastic. The Read/Write speed of 700MB/s! The early 2013 MBPR got around 350MB/s write and I think 500MB/s read. Has the Haswell processor which OMG lasts forever! As I said below after watching videos and using a VM with XP recording video with the Mac not even initially fully charged I still got half the battery left! A bit pricey but so worth it.

Regarding your tracking, I have a Nexstar also and here's a couple of tips I've picked up along the way...
* Perform either a 2- or 3- star alignment with a high-ish magnification eyepiece (reticle better) to centre/align the stars as accurately as possible. I've had some success with planetary viewing with only a solar system align on the subject, but the Moon is least good for this because it moves so fast
* check your goto approach settings - you want your final goto approach to an object to be the same as the direction of motion of the object to minimise the effects of slackness in the gears. Check in your scope setup that the azimuth goto approach is negative. The best setting for the altitude approach would depend on the balance of your scope - my SCT is back heavy, so I use negative approach
* to minimise the effect of slack in the gears, adjust the object in the view manually with the direction keys depending on the objects real direction of motion... for example, if the object is in the north and east of the meridian then move the object away so that to centre it again you need to move the scope with an up and left motion (note this is actual motion, not through the eyepiece), or down and left for west of the meridian. The left and right will need to be reversed if you want to track an object in the south.
Apologies if you've tried all these already, in which case I'm stumped  |
