Cone to IC447 in OSC

Recommended Posts

Data from Pier 5 @Roboscopes in Spain (Tak Epsilon 180, ASI 2400MC Pro, Paramount MX unguided).

30 x 240 sec subs.

Processed in Pixinsight. Not as beautiful as Olly and Paul's version, But satisfying nevertheless.

This is mine:

And this is the vastly superior Kummer & Penrice version.

A really interesting comparison. Yours is far more punchy and dramatic. I'm tempted to revisit ours from the linear stage to understand where these differences come from.

I really like your rendition.

Olly,

See my comment on your thread. The balance of the the calibrated and stacked data seems to be different. In my data, the nebulosity at the bottom of the image has the exactly the same intensity as the weaker parts of the main hydrogen emission nebula. Different sensors and optics? Different integration times and hence signal to noise? Different sky conditions during capture? Who knows!
