Can you please share how long exposures you can get with it guided and unguided? Does it work well out if the box without tuning? How easy is to connect it to laptop and what is required for it?
Considering I am using only guided imaging, I have had no need to tune the mount (training of the motors and similar, as called by Audiostar) which is recommended for visual use. I only used PEC training to reduce the periodic error.
For emission nebulae, I use SII, Ha and OIII narrowband filters and in those cases, my maximal guided exposure is 900 s, without elongated stars and is rather limited by sky light pollution. Since I am imaging from urban location, usually I use 300 or 600 s exposures. Of course, for imaging of galaxies, star clusters and similar for some bright objects I use LRGB filters combination and much shorter exposures.
The mount is pretty good for this price class and even better. It is cast from metal, except the motor covers and polarscope cover.
The maximal total weight (OTA and imaging equipment combined) I have used with LX85 is approximately 9,5 kg (max load recommended by Meade is 15 kg).
Connection with laptop is by RS232 cable (attached to the AudioStar handbox) converter to USB (to laptop). There are plenty of those cable compatible with Meade scopes on the amazon and ebay.
In the last few weeks, I am using AsiAir instead. It comes with ready-to-use RS232-USB cable and (contrary to many popular mounts), INDI-based Meade driver from AsiAir is perfectly working, so now I am using wireless connection and automation of imaging (except focusing, which is expecting to be supported by AsiAir OS in the next few months).
