r/astrophotography

Shot with Nikon Z8 through Takahashi TSA-120 with Takahashi 1.5x Extender. 1000 stacked frames, 40 megapixels. Stacked in AutoStakkert 3, sharpened in Registax 6 and processed in Photoshop.

This is one of my favorite images. I took it with my NexStar which is not supposed to be used for astrophotography at the modest f/10, but here we are. It gave me a lot of motivation to keep on shooting despite the frustrations that come with astrophotography :)

It's been a while since I haven't posted a picture on reddit, so here's my latest shot from galaxy season. NGC3718 is the largest galaxy on the right and many other friends scattered in the field. My RC8 is really suited for these galaxies, I can't wait to take more next new moon.

Hey everyone,

This was my first capture with a dual band filter. I used my Vaonis Vespera II and captured the Rosette for 4 hours. All processing was done in SiriL, then touched up in Adobe Lightroom.

I couldn’t believe how much of a difference the filter made!

My buddy told me there was a GRS transit so i rushed to take a picture. When I initially saw this other dark spot i believed it was some stacking artifact, so I stacked again to no avail.

Then I checked stellarium and lo and behold, I accidentally captured a Callisto transit with the GRS.

• Dwarf 3 (tele)
• 25 x 1/30th sec with 10 gain
• Straight output, no additional processing

The Moon was low on the horizon and was naturally this color for about 30 minutes. This was my first time shooting the moon with the Dwarf 3.
