All these items work together or separately. You can use the NGCMAX with the A-P encoders for standalone operation without a laptop. Or you can use the encoders with MG5 and ECU on a laptop, without the NGCMAX. Or you can use all of them together, with the NGCMAX at the telescope, and your laptop running ECU at your observatory's workbench. I'll sell the items separately or together. Make a reasonable offer if you want all three items. Make a reasonable offer if you want just one of the items. Just make an offer and buy this stuff!
