Mare Crisium and Crater Petavius

[ianaiken]

After mildly regretting to use my scope during the Lunar Eclipse I had to get a fix.  The moon was low down on the 29th Sept however it didn't stop me pushing.  Images are at either 2.3m or 5.8m focal length.  Imaged with a Celestron C9.25 and ZWO ASI120MM-S.

Very nice lunar shots. I like the detail in Petavius in particular. Thanks for posting.

[ianaiken]

Thanks everyone glad you liked them.

Very nice indeed

Shots good many people, I also lost the eclipse and photographed the same regions to pay.

A suggestion is allowed to me, the 2nd one and the 4th photo are with enough noise. Because you do not try to use deconvolução with the Fitswork to correct it?

These are really good, especially numbers one and three with their rich, crisp detail.

Thanks!

Thanks!  I think the images are noisy as I didn't use too many frames in the stack to produce the image.  They were noisy prior to deconvolution.  I did not know about Fitswork but I have just downloaded it and it seems to have some useful tools.  I did a very quick improvement image 2 and it did reduce the noise.  I think I need to find a tutorial on the tool.

Very nice. I like the first

one the best. Well done.

Ideally the moon is to stack at least 200-250 frames, of course the more the better. I normally never use smaller batteries however will all depend on seeing and camera capture speed. The ideal is to work with 30 fps or more, lately using the new ASI 224 have obtained speeds between 60-130 fps in frames of 1280 x 960.

+1, outstanding work.

Try using ImPPG for Deconvolution. that is also very handy. Some evenings you can't even use a x2 though....seeing in this country can be a bit pants ;-)

Frame rate was around 60 fps with the ASI120MM-S (USB 3).  I probably need to stack more frames then I did however with a bit of work in Fitswork I see to have removed the noise as well as a little more sharpening.  However too much sharpening adds a lot of contrast which I don't like so much.

Here is a reprocess of Mare Crisium:

Improved! Yes, to reduce noise in Fitswork increases the contrast so you can not exaggerate primarily to pull the layer 2 and layer 3. A tip to reduce the contrast is lower layer 4.

I also do not like lunar images with contrast too but when the picture is near the terminator is almost impossible he did not express strongly.

Thanks Astroavani for the feedback and also the original lead to Fitswork!  I've been trying it on some DSO images and it's great for some final processing.

Superb images
