lucky you Hector! The seeing here is yet to reach the level you describe
First time I aimed my 12" at the Homunculus I could easily see the almost stellar brightening you describe and in good seeing both of those lateral jets coming out of Eta Carinae. I was surprised, as these couldn't be seen at all in my 10" reflector. But on one night a couple of weeks ago, the seeing was good, I had the 10" upto 312x and I could see the stellar brightening and one of the jets. The 12" however is far superior on this object!
I have viewed the Homuncculus in an 18" obsession, but seeing was horrid and consequently it didn't even stand up to the views in my 12" dob
It is a very unique and interesting object isn't it? Another exclusive southern hemisphere spectacle. Goddamn we are lucky if you think about it!
