Browsing my regular haunts in Ret and Dor last night in the hunt for the elusive sn and noted a couple more for your list.
Key facts - transparency -8 seeing -8. Instrument 25" f5. Main eyepieces 17mm, 12mm and 9mm Naglers. Limiting power 530x - limiting mag 16.
NGC 1672 loose barred spiral, mag 10, 6'.6 by 5'.5. Observed at 187x and 265x. Higher power better compormise for contrast. Bar trends E-W, N arm can be traced for almost a half turn, the S arm much less distinct. Two brighter stars decorate one arm and a triangle of 15 mag stars fills the gap between the bar and arm. The nucleus is much brighter than the bar.
Also to reiterate other posters reccomendations for 2997 - absolutely stunning.
If there's interest I'll post my notes on these.
cheers,
Andrew.
