Jewelbox (NGC4755), Mimosa and DY Crucis

Hi all

Here's an image taken back on the 1st March, of the Jewelbox and surrounds.

It's a combination of 17x 60s exposures and 6x 3-4 minute exposures, all @ ISO800 with the unmodded 350D + ED80 + WO 0.8x reducer.

My polar alignment wasn't very accurate so there's some elongated stars in the full version, but luckily the websize hides most of those nasties

The diffraction spikes were created with some wool sticky-taped to the dewshield. it's all I could find at the time

I'm very happy with the colours in this shot - next time I'll stick to the 60s exposures and just do lots more of them. With long exposures, the jewelbox just gets washed out and completely saturated.

It's my first image of one my favourite open clusters in the sky, so I'm happy to have captured it finally.

Thanks for looking.
