It continues to impress me, those landing rockets. New Glenn reminds me - even more than Falcon or Starship - of the Thunderbirds.

Hi there. A bit of #astrophotography madness for you. Did you know that mounting a reducer on an @celestronuniverse.bsky.social #EdgeHD925 can be a challenge? When there is a #ZWO #EAF mounted too, you need to reduce the bracket as well. #hacksaw

Should’ve done this much earlier. I got a 9.25” @celestronuniverse.bsky.social #EdgeHD in july 2023. But it wasn’t until last night that I mounted the 0.7x reducer.

This movie shows the bubbling surface of a distant star, as captured with unprecedented clarity by the ALMA observatory.
R Doradus is a huge star. Each of these bubbles is 50-75 times the diameter of our entire Sun! 🧪🔭

My M51 project obsessive data mongering is done (for now). Curiously it was only the 4th time I was imaging this very well-known target.
As I have only been sharing the crop, I thought to also show the full field of view.

Need to play with my data a bit more, but I am thoroughly impressed with the new @siril.org and its ability to stack and stitch mosaics.

Editing my data of M51, I tried pushing it to the extremes. I still think it is awesome to see so much resemblance between my @celestronuniverse.bsky.social backyard image and that of @stsci.edu #HST Hubble Space Telescope.

I think I need some help from an actual #astronomer like @drbecky.bsky.social. Please share if you know someone who can help me identify the high proper motion stars in my comparison of M51 with a 20 year old @spacetelescope.bsky.social HST image.

No, it doesn’t seem to be an actual starry sky that shows when starting the app 😅

Did you see my attempt to shoot M51 yet? Take a look at my profile for more info.
Tonight I am adding Ha using the #optolong #LeXtreme filter. My #ZWO camera is doing just fine with it!
@siril.org does the rest 😇💪
This is just a teaser…

Work in progress. M51 has somehow evaded my attention in my #astrophotography. I have some sets of data on my harddisk, but nothing to really be proud of.
That is going to change, now I shoot it with the EdgeHD 9.25”. Perhaps I should start adding L-eXtreme data to it.

A month ago I posted about an Einstein Ring which I photographed with my backyard EdgeHD 9.25”.
Since then I added more data (611x180s) and with careful processing it got a bit clearer still. See #Hubble image for comparison.

Last week I shared a small clip of my rig. With it I have been imaging very small targets lately. The Celestron EdgeHD 9.25” at f/10 brings me real close in to targets.
I enjoy comparing my images to those of the famous Space Telescopes (JWST and Hubble)
