Nice shot of Clavius. The focus is excellent. It is the best stuff you have posted here. Try making them a little brighter, with a bit more contrast, and they will really stand out.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

Hi Aratus thanks for the comments,I will make it a bit brighter to get the contrast by increasing the exposure setting on the camera.
Thanks

Simply increasing the brightness on the Clavius photo you already have will make a huge difference. But, yes, you might need to better expose your original shots, or increase the gain. Try exposures no lower than 1/60th second if you increase the exposure time, but I find that using an ISO setting below 400, makes no difference to stacked shots. If your ISO is below 400, try bringing it up to 400.

Hi Aratus I have modified the brightness on Clavius to hopefully bring out a bit more detail,thanks for your comments once again,I will continuing taking advice as it certainly helps me with the astrophotography as I do not get any help from the astronomy club that I joined a year ago.
Thanks

You can get even more out of it. The midtone in particular is very dark, and the highlights are quite dull.
Here is an example. You can see that it brings out some finer detail by stretching the difference between the midtone and the lighter features.

Hi Aratus thanks for showing me how my image should look like,I will have a go later and see if I can match as I am using gimp software.Thanks for your time much appreciated.
Thanks

Hi Aratus here is my second attempt and found something that stretches the contrast in the software.If you think needs more detail or think it is any better.
Thanks

It is a lot better. I don't have Gimp, but somehow you need to stretch out the midtones without bringing up the dark. (There is no detail in the dark areas, just noise).
If you can't find out how to bring up the midtone, perhaps you can do it again but only increase the contrast until just before a point where the black sky starts to show noise.

In any event you can now see some landslips, and the remains of the central peak. There is also hints of the 'splash' beyond the crater rim.
