Unfortunately, clouds ruined their view and they had to go to bed.   Tried to wake them but it was impossible.

 

These are raw DNG images and are fine out of the camera. But can someone bring out the few stars I see and adjust contrast and sharpening?   I think these can really pop if the right person can give them a go. That person is not me. LOL.

 

I used a SV105T with a Nikon D5300 h-alpha modded.   An IDAS D1 filter was in the mix since I was frantic and didnt have time to remove it.  Seems fine and the data seems good.

 

You can PM me with a link to your altered file?   Theyll know you processed it :-)

Please stop calling a lunar eclipse, a blood moon.  All lunar eclipses turn the Moon reddish.  The term is made-up and based on events that ended in 2015.

This is what my data looks like.  This is a raw image out of the camera.  There was alot of mist and smoke in the air.

unfortunately I am not good enough to help. I can't bring out the stars without bringing out the sky glow. hopefully there is someone else on CN who can help.

Ditto here - skill set not able to help.   It appears to me that these are 8 second exposures.   I am just not sure how much actual signal is in there to draw out.   When coupled with a pretty high dynamic range for the image, I think it will take a Pixinsight master to draw stars and an inky black background out of this image....

I gave it a try.  The moon is way over expose so like Tom and Even, mine didn't come out very well.  But here is a like to what I got, so have a look: https://www.dropbox....rocess.tif?dl=0

I used ISO 200 and 400 and it was shot with an 8 second exposure tracked. I was trying to keep dynamic range and have been told that ISO 200 or 400 is the best with my Nikon. What should this have been shot at? Thanks for trying at any rate I really appreciate it.

I think that trying to shoot the full moon AND get stars in the background in a single image is truly the rainbow unicorn of astrophotos.   Perhaps at an extremely wide scale someone could pull it off (I saw some in all sky cams) but at this scale I don't think there is a viable way to get a proper lunar exposure and get background stars.

"rainbow unicorn" lol. Honestly the image looks pretty good as it is. You can do some sharpening on it to pull out a bit more detail on the moon surface.

At ISO 200 I would think the eclipsed moon would warrant about a 4-5 second exposure.  We had clouds here so I didn't get an opportunity to shoot it myself.

I got crazy and played with the DNG images in CS4 camera raw and came up with this mess.  Lol. It really would take a Pixinsight master to do what Im asking.  What about forget the stars and bring out moon detail and such?   Ive got halos around the moon in these bevause I cooked em too much.

Here is what I was able to get using PI and PS. I integrated all the images and processed the stack the same as I do DSO's. 

Thanks for sharing, I was unable to photograph that night even though we had clear skies.
