Glad to report that I have managed to flash AstroBerry onto an old SD card (only Cat 4 but at least it works) and it looks very good. And it’s free. It has KStars loaded, PHD, an imaging app and heaps of other stuff. I’m going to have some fun with this, I can tell. Stellarmate looks very polished and no doubt it a great package but I plan to walk before I run with this. Can I bully another body to give this a go?
