It is clearly Bode season. This is my final processing (probably) of M81/82 collected 22nd Feb to 2nd March. [he background might be too dark though]

Location: Bromley (Bortle 7)

L comprises HaO and a contribution from RGB
Chrom comprises HaRGB

Total imaging time: 7 hours

Sharpstar 15028 HNT
ZWO ASI1600MM Pro at 10C
iOptron CEM 25P
ZWO HaO, Ha, R, G and B filters
ZWO ASIAir Pro

Processed in Pixinsight, finished in Affinity Photo 2

Regards,

John

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.
