A great write up Bryan. Also a good save with the dome dropping off maybe a zenith table as a next construction project.

I’ve been after a faster nVidia card for ages so great that you managed to source one. All the bitcoin miners have pushed up the scarcity of such cards and if you can get them the price is at a premium.

Beauty Bryan! It makes me want to go back and re-process mine! I did a quick pass when I took the shot.

 

Sorry to hear about your dome falling! From time to time we ship Quick Relaease Brackets to the UK/EU for those who make their own Zenith Table. If you send me your address I can cant get a mailing price?

 

CS!

Thanks Wayne, as I said no harm done to dome etc , I’ll send PM.

I use this process flow to create the false SHO

But I gave the blue/Oiii a slight histogram stretch to help colour boost. I also found the background has no green so is a very Deep Purple ( Ha!! Space truck’n and so much more) anyway I add in a masked copy of the original L-extreme image to mix the original background to get it Back to Black !

 If you use ezDeconv it generates the required mask.

Yes, nicely done. I use Lukomaticos "Hubble for OSC" (Youtube) w/ IDAS NBZ for f.2 instead of L-Extreme, which many use with higher F ratios. Here's my 2 hour shot.  You got more detail and "black".  Taken with 14" Edge , Hyperstar,  and 26C. Plus I like your "non-halo" stars.  A trade off with 120 second subs and the Hyperstar for fast acquisition, is Halos around brighter stars. I'll "take it" though for two hours of acquisition. CS!

Oh! Forgot to say. Thx for mentioning the GPU thing for PI. I went out and bought a got suped-up Nvidia just to do that, and couldn't get it to work as per instructions. A buddy said the same so I didn't try again. I will now that you mention it works for you. 😉

If its a RTX30 series then there is a thread on Pi forum 

https://pixinsight.com/forum/index.php?threads/no-luck-with-starnet-on-rtx-3070.15585/

post #13 has the info I’ve copied below

but in summary you have to use updated libraries that support RTX 30 series GPU

 got it working with the 30xx video cards.

Install Tensorflow GPU 2.4
Install Cuda 11.0 (not 11.1 or 11.2)
Install Cudnn 8.x for Cuda 11

https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-gpu-windows-x86_64-2.4.0.zip

 

CUDA Toolkit 11.0 Download | NVIDIA Developer
https://developer.nvidia.com/cuda-11.0-download-archive

 

cuDNN Download | NVIDIA Developer
https://developer.nvidia.com/rdp/cudnn-download

 

The windows environment variable then has to point to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.0\bin
