Description

NGC 3572 cluster and associated nebulosity including the "southern tadpoles".  194x5m exposures with EdgeHD11 at f/10 and 0.28" per pixel.  No processing other than slight crop and levels in photoshop.  Raw fwhm's ranged from 1.0" to 2.0" with most below 1.5".  Video guided with OAG and MetaGuide on CGX-L.

The interesting feature in the upper left may be a "photoevaporative globule" as described in this article.

I started imaging in Oiii also, but it was very faint so I just went with pure Ha and grayscale.

Credit to a recent apod for the idea, along with a few nights of good seeing in Melbourne.
