    Apologies for uploading a lot of 'old' data, no time at the time to go through all of it & have only just done so. Some ok some not so great but thought I would share them as our star is pretty quite at the moment with surface action. Thanks for looking. 399.tif

    I've reprocessed the stacked image using a masked stretch, followed by a light stretch with histogram transfer then HDRMultiscale transform a bit more aggressively on the core. then combined it with the original image using pixelmath. This was a bit of trial & error as I didn't really know what I was doing but it seems to have worked. The core is much better and the overall image is a bit softer.

    Very Nice, Charl! For what it's worth, I am quite happy to stick with a (rather similar) unmodded Canon 100D - I reckon response is ~1/3 in the region H-Alpha... But that's only just over one magnitude... Repeat until it sounds convincing? The Pleiades are BLUE anyway!

    Very nice David, needed some Ca-K images, seeing was a bit better here today but given how bad it's been lately that's not saying much Dave

    Thanks guys, I've reprocessed and fixed some of the issues, but I think it maybe a bit harsh still. Oh well, always learning.

    Hi,I have an AVX as well - it is not so much of a problem; that's my grab and go. I've cut sections from the mount packaging to dit things like power supply, the 1.25 CCDs etc. Tripd juts go in the back of the car easily. The CGEM-DX mount is quite bit bigger I've had to take the feet of the legs of the CGEM-DX mount to get it in the boot. With the 200P-DS theres space for the mount - if it's not in one piece. As i said, i saw something where someone noted that the CGEM-DX mount split neatly to two parts - I just don't know where it would be safe to undo bolts to find out. Would be nasty if I got the wrong bolts and all the spring sea gears fell out I've already removed the losmandy plate to reduce the volume.

    Thanks for the guidance. I actually used the adaptive stretch which I'm now getting fairly used to. I might be mistaken but when I use this it doesn't seem to give much room to further stretch it without blowing out the image. I'll have a go at the masked stretch and compare. I'll also try a combination of two stretches of the same stack, I've done a similar thing on some landscape images to bring out the sky but hadn't considered it with Astro. I used the subframe selector script to analyse the lights and tried to stack them according to the assessed weights. However I kept getting an error message to the effect that imageintegration couldnt find the fits keyword that was embedded in the subs. I couldn't work this out because when I opened the properties of the individual subs the keyword was clearly there. I wonder whether it was because I was working with xisf files and not fits. I'll have to ask on their forum. I ended up stacking according to the weight of the noise, I don't suppose it made much difference but I'd like to get to the bottom of it. Anyway, it's all an interesting learning curve edit, I think I might have found the problem, just read a post on the pi forum about negative weights, i need to check but I think some of my weights were negative.

    This may be my last image of Saturn this opposition. It's getting very low now even at dusk. Best regards Peter
