I don't normally do two sketches in a night, but it was a nice clear night for a change. Wasn't gonna waste it. I just came off a failed attempt to observe PAL 2 on a revisit, so these two magnificent objects were real eye candy 

 

NGC 1360 is huge and fairly dim without a UHC filter. With the filter, it really popped nicely. Some dark areas were seen near the central star and along the eastern edge. The northern lobe was noticeably brighter. No color seen. 

 

NGC 1535 is very bright. We're not supposed to use UHC filters at high magnifications, but doing so helped tease out its weakly annular structure. It was plenty bright to be seen, though the central star was best seen without the filter. There was another fleeting star near the northern edge of the nebula. I do not recall any color, need to work on that. 

 

Both very beautiful nebulae.

Hi Norme , Both excellent objects, Ngc 1360 doesn’t get real high in my sky, so I have never really seen a fluctuation in brightness. Going to have to revisit. NGC 1535 is a beauty, really well captured and excellent report

Thank you. Raul. Please visit them if possible. Both were at or above 48 degrees altitude, I caught them near their peak altitude close to the meridian. I don't know what effect extinction has on it. Some folks say 1360 is bright. Can't argue, really, because it was readily visible at low power. It has a moderately low surface brightness, but really pops with a UHC filter.

I have never seen these two before spending most of my time north of 35 degrees latitude where they ride 20 degrees lower in the sky. Also focusing on planetary observing in recent years. I was shocked at how easy they are to observe from 15 degrees north and blessed with rare very transparent skies.

There are not many sketches of NGC 1360, maybe because of its lower altitude for northern observers. However, there are a few sketches of NGC 1365 which is a little higher in the sky for everyone. It hits about 60 degrees altitude here.

Anyway, these are two beautiful object's, I'd urge everyone to try them. Even if low on the horizon.

Norme,

 

Both are excellent renderings.

Fine sketching posts.

 

Frank :)

Nice sketches. In your second sketch, wouldn't the magnification be 500x and not 240x?  (8" F/6 and a 12mm HD 60 and 5x focal extender).

Yes. I mistakenly listed the 12mm rather than the 25mm HD 60.

Thank you for catching it and to each of you for replying.
