Mosaic of Eta Carinae nebula in H alpha

CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!

Mosaic of Eta Carinae nebula in H alpha

Post by tanguan2001 »

All,

Have started making a mosaic of the Eta C region in H alpha. Mosaic of 2 images is at this page.

Also started to use Neat Image for noise reduction - default settings are not good, but less aggressive ones give decent results.

View in full screen mode - the pic is big! Don't know about you, but the nebulosity suggests some strange things to me - a crab, a duck and even a skier! What do you see?

So far only 2 images together, but I hope to enlarge the coverage.

This mosaic has now been extended to include 4 frames, covering about 2 deg of sky north-south.
