To override the 30s limit on Nina, you may need to change the camera setting to "bulb" mode. On my Canon 1000D, you needed to change the exposure to 30s, and then move it up, one more. This will allow you to use exposures from very short to about 30mins. I found that cameras generally shut off at about 30mins of exposure. Overall, Great image for limited exposure

Lachlan, the camera was set in bulb mode, but as soon as it connects to Nina, it switches to “PC mode”. Apparently this is a Nikon problem. I hear using the snap rather than the recommended direct PC connection might override the 30 second limit. I’ll give it a try.

You spider vanes are not square meaning your secondary is offset. That's the double spikes. The "wiggle" is just colors diffraction. Pretty standard. |
Thanks Marc! Yep, looking to get longer exposures and more integration. Hopefully I can fix that secondary mirror issue. My main issue is that really heavy noise
Oh, and thanks for the focus compliment. I don’t even have a Bahtinov mask yet, so I’ve just been zooming in on stars and tweaking until thy are as small as possible wit bright density at center. The double helical focuser is just amazing.
