I’m in widefield mode for a while and wanted to grab this one before Cygnus gets away for the season. 70 minutes each Ha and OIII

Next-to-last image with the Meade for this season.
12″ Meade LX850, QSI683WSG-8
Six exposures of seven minutes each R,G,B.
This was the last capture before tearing things down to permit sending in the outboard SCT focuser for service. I’ll be using the FSQ-106N until I get that sorted.
Twelve exposures of ten minutes each L, nine exposures of five minutes each R,G,B.
Undermounted? ; )
The LX850 is breathing a sigh of relief after being unburdened of the 12″ SCT. It’s been replaced for now with the FSQ-106N. Dunno what that weighs (it is VERY heavy for a 4″ F/5 telescope) but it’s obviously much less than the Meade.
I’m winding down on the long focal length stuff. The aftermarket add-on focuser I use on the Meade needs to go in for service so I’ll be switching to the FSQ-106N for a while. I still have a couple of images captured with the Meade to post but those will be the last until I get both telescopes set up side by side.
Finally had some decent seeing last night. No deconvolution or sharpening required. Starlock did a great job at .88 arcseconds/pixel. 8 exposures of ten minutes each Ha and OIII, artificial green channel. I will tone the red down when time permits but here’s what I have so far.

Finally – another RGB image. Narrowband filters won’t help with this one. It’s very dim. I just wanted to see what could be done with it from my urban location. It isn’t great, but it’s much better than I expected! Seven five minute exposures each R, G, B (no time for L on a work night). Usual gear; 12″ LX850, QSI683WSG-8.

I’m kind of locked into this bicolor narrowband mode – but at least I stumbled onto an appropriately sized target this time. It’s a nice, big planetary nebula. As usual, the sky didn’t cooperate during the weekend so this was another worknight (read “in a hurry to get to bed”) shot. Grabbed an hour each Ha and OIII. Still using the 12″ Meade LX850 and the QSI683WSG-8.
Can be seen at http://astrob.in/108701/B/ and presumably that one will get updated as time is found to tune up the processing.
Not a great night fopr imaging; transparency was as bad as the Clear Sky Chart said it would be so even with 8 minute exposures it was noisy. Cleaned it up as best I could in a hurry so I can go to bed (work day tomorrow). I might be able to do a more gentle job later. 48 minutes each Ha and OIII, 12″ Meade LX850, QSI683WSG-8 – as usual. I’ll be switching to the FSQ-106N soon. This target makes much more sense at that scale!

I don’t remember the last time I was able to image two nights in a row! This is 8 exposure groups, each with 5 minute luminance and 100 second R, G, and B. Still with the 12″ LX850 and QSI683WSG-8. Larger version at http://astrob.in/105711/0/ .
I know it’s time to switch over to the FSQ for nebula season but I’m still having fun with the 12″ OTA so I’ll probably do a few more inappropriately large objects with it. This is a bicolor image, using Ha and OIII filters. The OIII is mainly to give me some star color.
