M13 RGB via the C11 @ f/10

I am extremely pleased with the outcome of this one 🙂

It took a while to get the C11 sorted, getting the SXV M25C in focus, and then getting the Off Axis Guider parfocal…. never want to do that again, but the result was just incredible. Perfect round stars, even when imaging at 2800mm focal length from a mount that was outside. The data was so good that I managed to drizzle stack this for 6000×4000 and the image data is still incredibly good…

OTA: C11 @ f/10
Guiding: C11 @ f/10 + Celestron OAG + DSI-C+ PHD
Imaging: M25C + MaximDL, 28×300s, IDAS
Stacked: DeepSkyStacker
Post Process: PSCS2
