Chrom comprises HaRGB

Total imaging time: 7 hours

Sharpstar 15028 HNT
ZWO ASI1600MM Pro at 10C

Is this a reprocess John as I already have M81 and M82 from you, same FOV.

Hi Carole,

It's my third attempt at imaging M81/82. I have added some more data to an image that I put on WhatsApp and reprocessed it. It is probably because my setup uses "plate solving" to locate targets and so ends up with similar FOVs if I repeat a target.
