Advice on dec extension was created by wsuyker

Hi,
For my mobile setup, I want to mount a RASA 8 (ca 8 kg + camera) on one end of my Uno Dual, and a Skywatcher Evo 72 ED (ca. 2 kg + camera ca ) on the other end. Even in the lightest position (dec moved max towards RA), the RASA is too light to achieve balance, so I need a dec extender.
Could you give me a hint on extender type (modular or massive?) and required length?
Thank you, Willem

Hi Willem

We suggest an Extender 105 mm kit.
Mini Extender 105 mm kit

Below a sample picture setup with M-uno D mount (Raw balancing B-3 position, paragraph 4.2 Balancing, page 18, M-uno manual) with Rasa 8, a 2kg Telescope guide on the other DEC side and a 0,5 kg counterweight.

The setup so configured is fine balanced.

Best regards
