Hi all, thanks for all the comments and the likes
I meant to add the capture and processing details, but after processing these things for most of the day and into the night using different sharpening techniques, contrast and level settings etc I was too tired and just put out whatever I thought looked the best at the time.
To the specific questions ...
Not too shabby! It's hard work this early in the "season", lots of frames end up in the bin ...
Which OTA are you using the days again? You got a new one from memory?
Thanks Darren, yes I should be able to clean up about 50GB of hard disk space. I'm using the 9.25" SCT exclusively now, with a 2.5x PowerMate and short TV adapter which appears to be giving me a focal ratio of about f/20.
Not bad! Are these using the same color settings from your other thread? If so, any additional balancing in post-processing?
Thanks, the Mars image was using my so-called "daylight white balance" settings from the previous post, Wred=62 and Wblue=99 - I played around with the auto-WB setting in PS by pointing it at the white (polar ice?) section at the top, but it made virtually no difference so I left it as it was. For Jupiter I toyed with leaving it as captured or autobalancing the colours in Registax, I eventually went with the Registax auto-WB settings of R0.99 G0.99 B1.07 (so a bit more blue) to counteract the supposed reddening from the atmosphere, so it looks like I've come full circle on that score. If only there was a nice 18% grey card in space ... . But I guess the G2V star approach is the closest I can do on that score. Mercury was of course a colour mess as I don't have an ADC and was shooting without filters (except the IR cut), so I shifted the red and blue channels in Registax to try and get some sort of balance, then reduced the saturation in PS to give the whit-ish colour attached.
Celestron Evolution 9.25" SCT @ ~f20 with 2.5x PowerMate, ASI 224MC with Wred=62 Wblue=99, 25 or 33% stacked in AS!3 with 3x drizzle, sharpened in Registax, final touches in Photoshop Elements. Hovering over the images will give you an idea of the process.
