The DDM85XL premium mount has already received its laurels from acclaimed astrophotographers world wide. Many of them have completely abandoned extra auto-guiders and therefor don´t have to sort through a variety of images any more. The DDM85XL can be be run on a 12V power supply and powered by a single car battery. Since the DEC can be separated from the REC axis, the DDM85XL can still be transported with ease. All power and data cables are internally lead through a large dimensional hollow axle. The mount can also be fixed to an equatorial pier (optional delivery) rendering meridian flips obsolete.
 
Carrying capacity 100kg (220 lbs). Used in combination with a custom made equatorial pier, rendering meridian flips unnecessary.

The tracking accuracy is excellent and therefore in most cases one can turn off guiding. Tracking without correction via autoguider over a period of one hour shows 0,68” peak to peak and 0,18” RMS, respectively (the setup used for this record was: ASA DDM85XL and ASA 16N OK3).
