I decided to give something different a go last night. Rather than imaging with the ED100 (F9) I decided to do a bit of wide field astro with the Sigma 70-200 F2.8 at F3.2. Here's only a short exposure of M43 with the horse head nebula already visible (15x1 min, 8x30 seconds). Bit of a pain that the tropics are heating up now
