Sometimes I like to do live imaging just to get immediate results.
This is from a 2 hr session last night, just after the moon set. Done on my ASI224MC (which I has just got the amp-glow circuitry upgrade at ZWO).
These all done on f5.9 80mm refractor with focal reduction (~ x0.6 with a meade f3.3). Used a UV/IR filter. All images at high gain (250), 15 sec subs. Total exposure of 1min (the two clusters), or 4-5min. No guiding.
Images captured and stacked in sharpcap then automatically opened and contrast/colour adjusted in astrotoaster. I ran this on a PC stick attached to the scope which was remotely controlled via wifi from a laptop indoors.
I've crammed the pics together, but haven't done any post-processing.
Edit-have made images larger at the expense of extra compression
Nice group Chris. For saving time you can't beat a OSC camera. Instant gratification doesn't happen in the mono world, although it does have its own benefits. I have been playing around with my new Nikon this week, so nice.
Thanks Colin and Glen. I'll take the noise and coma for a bit of instant gratification.
I've also been doing a bit of EAA with an H-alpha filter on a mono asi290. Either on my guide scope on the 80mm refractor. I crank up the focal reduction for that.
Those look terrific to me! Well done. I have a ZWO 224 MC too. What is an amp glow upgrade?? I havent used it yet on account of the fact that I have forgotten where the stars are, thanks to this awful weather here in TAS! If you can get photos as good as that without guiding, why does anybody bother to guide? I guess it's like Mt Everest (famous quote "because it's there!")
I got the first 224 that came out which had the ver1.1 sensor board. It had bad amp glow. ZWO did some amp glow reduction mod for it. This is on the ver1.3 board.
If you bought yours recently is probably 1.3.
If you see bad amp glow on one side of the image at highish gain and subs over 10sec you have the older one. You can check by opening up. The version is written on the sensor board.
If you don't see the amp glow don't worry about it. It's all on their website.
ZWO do a replacement for US $49 plus you pay postage to China. Its a nice little camera for EAA or planetary.

These cameras are much cheaper now as they have a competitor Rising Tech who are selling similar cameras similar to zwo. Plus they have their own software. They are on aliexpress. Link here http://astrovideoforum.proboards.com...g-tech-cameras

Chris i could not get the Rising Star links to work, but it maybe due to being the middle of the night and Aliexpress is apparently down. Regarding the 224 with the fan that could be very useful, it could be simple to add a TEC to create a cooled 224.
I had a ZWO224 which i just sold, it was fine for planetary, which i played around with, but for DSOs i don't know. The chip is pretty small and my 1600 is so good at DSOs. I would like to try the 071mc but its too expensive, like four times the cost of a Nikon D5300 at the moment. I bought the Nikon obviously, great camera so far.

The link I put up was to another forum where we have been talking about RT cameras.
And there's a few others there. I don't think any have calling, but they have fans
The 224 is one of the favourite EAA cameras as it's so damn sensitive (much more than the 1600). And it has low read noise so we can use really short subs live. Plus they improved the amp glow (it was horrible before).
Can't imagine it would be any good for AP as it's a 1/3", has small well size, is only 12 bit. So I imagine you might find it fairly ugly.
Donboy over on the CN-EAA forum whacked an ebay peltier/heatsink on his 224 and got nice cooling. But he used the zwo camera - I think its body shape is better suited for cooling the sensor ? https://www.cloudynights.com/topic/5.../#entry8009960
But most don't bother as they are doing such short subs.
