IC405 aka 'The Flaming Star Nebula'

[RobertM]

One from January this year.  The area of nebulosity affected by the 6th magnitude star AE Auriga.  AE Auriga is an O-type main sequence dwarf star traveling at high velocity causing bow shock wave disturbance and excitation of IC405.  It's speed and direction have been attributed to a collision of two binary star groups in the Trapezium Cluster in the Orion nebula.

It really needs more subs for extra detail.

It's an amazing piece of work Robert
Unguided for 600S at f7! - just out of my league.
For that narrow a field it has a huge amount of detail.

Thanks Noel. 

It takes time getting to a stage where the equipment is doing what you expect.  I think you're doing far better than I was at the stage you are.  There's just so much to learn and many frustrations to overcome.

Very nice and smooth Robert.  So if you are not guiding what mount are you using to enable 600secs subs?

Thanks Carole.

I sold the Paramount MX, which I never really gelled with, and bought a used 10micron which has been superb so far.  The smoothness is down to getting to grips with Pixinsight TGVDenoise.

Ah yes, that makes sense.
