Hi! I tried to do some widefield imaging for a change. 25x600s h-alpha with ASI1600MM-C and Canon EF 70-200mm f/4L (135mm). I piggybacked them on Taurus Hill Observatory's Paramount ME mark I. Luckily the main scope has free vixen dovetail bar on top of it so it was easy to attach. Also I replaced my laptop with much smaller imaging PC (LattePanda), it worked really well with SGP which suprised me because its so small. I will definedly use it more in the future for grab and go systems.
To me NGC7822 looks like a question mark.
Here is the wide field taken with the 135mm Samyang (@ f/2) sitting side by side with the 5" reflector (which simultaneously took the close up of NGC7822 that I previously posted). Not sure if this was the best object for a wide field since and it was a bit odd to process such an undersampled image (6.6 "/pixel) with so many stars. Still, I got it for "free" while I took the close up with the 5" apo.
I post also the close up for comparison.
Equipment: Samyang 135 f/2 with a Canon 70D (ISO 1600) side by side with a ES 127ED apo and a Canon 60Da. All on an EQ8 on a pier in the obsy. Guided with PHD2 and a SW80 with a QHY 5LIIM.
Exposures: Samyang 100 x 1 min. ES127 31 x 8 min (both at ISO1600)
Comments most welcome!
Finally last night the sky cleared, the moon was below the horizon and there was 6-7 hours of astro-darkness up here. So here is the first data I have captured this season.
Gear: ES 127ED apo, Canon 60Da, EQ8 mount. 31 x 8 min, so 4.1 hours. Stacked in Nebulosity 4 and prosessed in PS CS5
I also had my Samyang 135 f/2 with a Canon 70D side by side (hopefully 100+ good 1 min exposures). Will have a look at that data later today (when I may be exposing again, weather permitting)
All comments and suggestions most welcome!
