I took these images on Sat 25th Nov from here in W Oxfordshire. I've got the widefield setup running now using a RPi3 running KStars and Ekos. This controls a modded, uncooled 350d (with Baader filter) and a serial shutter cable, an Arduino motor focuser (as a Moonlite compatible focuser) and the Losmandy GM8 it all sits on. Images were taken through a Canon 85mm f1.8 EF lens at f4.5, exposures were 45 x 300sec (3h45m total) at ISO400 through an IDAS P2 filter. The field is a whisker over 15x10 degrees. Processing was in PixInsight and a bit of work in Photoshop to reduce a bit of amp glow that didn't calibrate out fully. Fairly pleased with this (though the Heart and Soul have come out maybe a little red - the colour calibration uses PI's PCC tool, and the IDAS filter might throw it a bit), but there's some other areas of interest coming through in the image. Annotated image attached but there are a few other bits that PI doesn't grab - there's a small area of reflection nebula (LBN 142.14+01.97) to the left of Sh2-202 that's just coming through. Also, unlabelled are Stock 2 (between the Heart and the Double Cluster) and for the interested clouded out astronomer, galaxies Maffei 1 and 2 are visible in frame just below the Heart (labelled as Sh2-191 and Sh2-197). Thanks for taking a look!
My first go at the heart and soul of my guided EQ6 era. I know I could have tweaked the framing a bit, or better still, zoom out a little to help get it all in. Maybe one for next time. There's a bit of residual gradient I didn't correct well enough, but what's that dark patch between the heart and soul? I don't have any dust there on my flat... is it some dust out there, rather than on my camera? Modified 450D, Astronomik CLS-CCD, Sigma 120-300 OS HSM at 300mm f/2.8. 22x2m with flats.
