First Eta

Well, it was windy down herein melb! Have to admit I was a little nervous outside a few times. Luckily we have no major trees near our little backyard to threaten the scope. My little banana scope, E-130D Tak, is so stumpy that I doubt it was affected by the wind. One advantage of a relatively light setup.

This is all I have from a bothersome night, but as it's my first ever Eta Carinae, I'm still chuffed. What a magnificent object that is. Mysterious thru a scope, like an amazing flame in the live viewfinder after a 10 sec shot.

I've read somewhere recently that most of today's SLR's don't really start increasing in noise until beyond ISO 1600, so tonight I tried 1250. Very pleased with the noise levels. Anyone else experiment with higher ISOs? I need to do more, to see if it really makes a difference.

Due to my alignment woes (a poorly levelled mount), I couldn't use the 1 min subs, shameful. Weird, also the EQ-6 mount seems to go haywire, I do a 2 star alignment and it doesn't seem to keep it, eg. tonight I had to manually find Eta.

But these, wait for it.....20 second subs, I was amazed at what I could see with just 30 by 20 sec subs.
