Hi guys,

M8 - The Lagoon Nebula,

40x240sec. subs + darks and 7x60sec. subs.
Modified Canon 1100D(T3).
Skywatcher 120ED Pro Refractor.
SW EQ6 Mount guided with Celestron Nexguide autoguider.
Location: Mountain Sanctuary Park, South-Africa.

Larger version:


When I captured this, I hadn't yet received the extension rings to position my camera the proper distance from the coma corrector, so this isn't the best image I would have liked to submit. This has been one of the wettest July's in recent memory here, so there've been precious few opportunities to snag photons, and none coming up before the contest deadline, so I'll go with what I have.

Date: 2013 07 07
Location: Gainesville, FL (backyard suburban orange zone)
Imaging telescope: Astro-Tech AT8IN
Camera: QHY8 OSC
Mount: CGEM
Guiding: Orion Mag-Mini, Orion SSAG, PHD
Frames: 13X300s lights, 9X300s darks, 104 bias, 19 flat lights, 19 flat darks
Filters, correctors: Baader MPCC-III, Orion SkyGlow Imaging filter
Software: Nebulosity 3 (capture, stacking); StarTools; PS CS6

Greatly resampled to fit the upload constraints, full resolution tiff available here

Thanks for looking, and clear skies!

Here's my M8 taken from my backyard on 6/16/2013. I used QHY8L color CCD through a TMB-130SS with a William Optics Flattener IV. All processing was done with PixInsight. Exposures were 19 x 300" and 3 x 600" through an Astronomik CLS-CCD filter.
