90min HII, 72min [NII], and 80min [OIII] in 2 min subs with the 80mm f/4.4 and ASI1600 MMC camera through 3nm Astrodons. Piggy backed on the 130 f/7 mounted on the DDM60 and encoder guided.
Sigma Add stacking in AA5, then gradient removal, alignment and Trichromy with [NII] mapped to Red, HII to Green, and [OIII] to Blue, following the Hubble Palette.
Multiple Histogram Stretches, and a Low Pass filter to get rid of some of the noise. The RGB stack needed a serious crop as the [OIII] subs were at a steep angle to the other data, which is a pity as I can see plenty of outlying detail in the individual stacks.
I'm not taking this particular image any further as the data is too short. I've already got another 2 hours of HII in 5 min subs which I'll stack and add to the existing HII stack. The [OIII] I think I'll bin as it's so badly skewed, I'll try to replace it with 5 min subs properly aligned. The [NII] is OK as it stands, but I'll try to add to it.
When I'll be able to get more data is a moot point, as the weather here has been dire. There *may* be a couple of windows coming up, but I'm not counting on them.
I started this zwo 1600 problem topic yesterday, but I couldn't get the answer. I have found that my problem is temperature related. when the sensor chamber drops below zero the download hangs. Sorry for the new topic but i am getting really tired of this.
Could you please help me out?
I have a 1600mm cooled version. I was spending Last couple of nights in field trying to do some AP, but the camera didn't work. Everything seems to be ok. I have temperature's info, the 120mm data comes in flawlessly, EFW works just fine. But when camera finishes the exposure it hangs on downloading. I reduced usb traffic, no luck. I switched programs, sharpcap, SGP, nebulosity and even maxim-dl. I switched cables, and again no luck.
I took my rig home, set up evertything and camera works just fine. Everything is ok. I took 40, 4 min frames, not a single problem.
Then I took it out last night, tried to capture, and again it fails to download and hangs on downloading.
It is getting really frustrating. Could you please help me out?
