Some of the images posted on here are taken using double stacked filters, which reduces the band width and gives a clearer view of the proms and / or photosphere and also through Daystar Quark units that give very nice images from what I've seen posted. ( drool )
Can't help much with the cameras though with my ZWO290mc I'm using , as rough settings. RGB24 format, shutter speed 5ms. Gain 50 , Resolution 1024 X 780. ( or something about that ).
Keep chipping away and trying different settings etc and it will slowly come together.

Thanks Jeff,
Focusing today certainly seemed a little trickier so, entirely possible that seeing wasn't the greatest though, visually, the views were stunning. There was still some cloud around, a lot of moisture coming out of the ground & humidity levels are still quite high. I have been having some issues getting raw colour images from the ZWO but, I think that has more to do with the fact I've been using a tablet to control the camera. I did some experimenting later today on some trees using Sharpcap & managed to produce some colour fits files using RGB24. Thus I think I just need to use the laptop & Sharpcap rather than the tablet or ASICAP on the laptop where even 16 bit raw is coming up grayscale.
Maybe focusing on video capture will yield better results.. more experimentation to follow I guess
Cheers

The way to improve your images is to go for a high speed (>100 fps) mono camera. The ASI 174 is popular. I went for the ASI 1600MM (a replacement for the defective ASI 183) to get the larger chip.
You'll need a FAST!!! computer, USB3 16Gb memory, and 500Gb SSD drive (I went for a sexy MSI gaming machine - goes like the clappers!!)
Then use FireCapture, with SER (12bit) video settings.
I found a SW focus motor geared to the 10:1 focuser almost mandatory to be able to get good focus.
Practise with the tuning to recognise when you're "on band" and take at least 1000 frames.
Use AS3! to find the best frames (10 to 20%?) and stack them.
Move to ImPPG and apply some corrections and unsharp masking to bring out all the available detail. Colourising in PSP etc. is optional.
Onwards and upwards.

Thanks Ken,
Can tick the boxes on fast computer.. USB 3 - check, 16Gb RAM - check, 250Gb SSD - half a check coz it's not 500Gb...
Camera wise, I'm pretty much stuck with the ASI224MC or the DSLR at present & I was a bit disappointed to find that with the 0.5x reducer I couldn't get to focus... not enough in travel. It's not far off full disc with no reducer so, might just stick with that to get the areas I want & then maybe work on full disc mosaics later. the 224MC is capable of 150fps so, might just have to stop being lazy & drag the laptop out..., might have to try my Orion SSAG.. it's mono but, have no idea of fps capabilities & have managed to make that work for imaging in Sharpcap.. although a tad clunky for gain control...
Have to start saving my pennies for a better mono camera in the future...
Setting up the EQ mount for the sun was a breeze, no PA & the sun pretty much stayed in the centre of the EP/sensor for most of the morning with the occasional tweak to put it back in the centre so, pretty happy with that outcome.
Haven't tried Firecapture as yet but, might give that a run as well... I did capture some video today but, need to get better at processing those.. AS2 did a horrendous job of stacking the video, as you say.. probably need to be a little more discerning in choices for stacking rather than just stacking the entire 30 seconds of video...
Cheers

Thanks Ryan, nothing like having multiple imaging learning curves on the go at any one time...

Cheers Alex... might just have to try that..
I've got a few yards to play with in the backyard...
