Excellent sketches
Hi PGC,
Another excellent report.
I enjoyed the sketches -- especially 246 and 55.
If you have a UHC filter it is worth a try on NGC 55 and enhances its HII regions more clearly -- though you've captured them well in the drawing anyway. An OIII filter is not as good because it won't allow H-Beta through like the UHC does.
A few other nearby galaxies are worth a try with the UHC to see if you can pick-out the HII regions. M33 in a large 'scope is one to try, as is M101 -- or so I'm told! NGC 1313 might also be worth a go (haven't tried myself yet).
NGC 7009 (Saturn Nebula) is a really lovely object in +10" 'scopes. As you've noted the ansae are best seen in good to very good seeing; though the knots at their ends are a tad easier than the connecting wisps. Without doubt, one of my favourite spring PNe in large 'scopes.
Well done again mate!
Best,
Les D
