Wide Field Milky Way Panels

G'day

We have had some awesome clear nights this week and I have been able to get these pictures.

I used a Nikor 85mm f1.8 lens stopped down to f4, and a Panasonic GX1 which has a 2x crop sensor, so really Im imaging at 170mm f4.

Subs were 128 seconds each at ISO 800.

The FOV is 11.5 degrees

I have generally been going out at around 8:30 setting the camera up and then going to bed leaving the camera happily collect subs until the battery runs out or the lens fogs up.

The first picture I don't know exactly were it is, I remember pointing the camera somewhere near the base of the neck of the Emu (Norma?), if any one can identify the nebula that would be cool. (70 subs)

The second picture again I don't know exactly were it is, I think it's in Scutum or Aquila? anyhow there is a big glob in the middle and what seams to be a reflection nebula in the top right hand corner? (40 subs)

The last one is pretty obvious with M8 and M20, I reckon this is probably the best of the three, the stars seem to be smaller? tighter? (90 subs)

Im stacking one at the moment of the southern cross and coal sack, its starting to look pretty good.

If anyone has tips/suggestions I would love to hear them.

I had a bit of trouble trying to down size them so these pics are not much compared with the original 36MP 16bit tiffs

Thanks for looking

Jo
