  1. I finally got some SII Data to add to my HA data and got them processed. 5 hours 20 mins of data. So here is my version. Mapped the HA to green and the SII to Red and used the HA as a LUM. I like the definition between the green and gold dust so i left the colors instead of changing to the HA gold like the modified Hubble. Thoughts? 8 x 1200s HA 8 x 1200 SII

    This is currently a work in progress. Playing around with Photoshop CC to try and extract more detail from this image. This image is not as cropped as the others I have posted.

  4. I grabbed 3h40m of the Sadr region stretching from the crescent up to NGC6914 (not visible as it's a reflection neb!), in HA light - may add to this in HA, but also would be nice to bring LRGB into it at a later date. QHY163M, Canon 200mm 2.8L II (working at f3.85), Losmandy GM8 - taken 17th Sept 2018, West Oxfordshire. All in 5min subs, guided with a ASI120MM on a 50mm guider. Baader 7nm filter. Processed in PI. Thanks for looking. (ergh - jpg compression artifacts aren't great in this

    Deneb and Sadr (Cygnus) | 50 30 second subs Dithering | 0 Darks | 0 Bias | 0 Flats Canon 650D Samyang 100mm 2.8 ED Skywatcher Adventurer Mini
  6. First light for this little 50mm f1.4, set to f5.6, and my first real foray into widefield really. Three hours total (5x1800s + 3x600s). AZEQ6 mount, guided with an Altair 60mm. Really impressed with how this turned out; the limitation is the camera resolution for a change, rather than the optics /seeing etc. The exposure at f5.6 was actually accidental - I thought I was fully open at the time ! I wrapped a small heater strip around the lens, and found I could focus no problem by twisting the ring through the heater. Capture and focus in Nebulosity. Of course, now I want some OIII, but tonight's probably not the best chance - with the moon an' all. Good chance to test the lens fully open in Ha though. I've not processed this beyond a stretch, so you can see what is really happening. Tim
