Using Continuum Subtraction on M82

Checking out a new way to subtract out HA from the red date. If you aren't using this script you should be!

You shouldn't have to reinstall CUDA just because you installed a new version of PI. Before you install the new version go to the bin folder and copy the tensorflow that you're using to a safe place like desktop, install the new PI, go back to bin and rename the tensorflow that was put in with the new PI install to something else, now copy your previous tensorflow that you were using and paste it back into the bin folder and you should be good to go.

I thought there might be an easier way. Thanks!!!

See my reply. Russ C to the rescue!!

Hey man, long time lurker here, why do you use division versus subtraction with DBE? I assume it’s not as harsh as straight up removing the data?

[@enteringintospace4685]

@ericknudson2387 thanks for lurking! Division is used when you have added gradients due to flats over correcting. Subtraction would be if the gradients is only caused during the imaging process. I tend to have a circular additive gradient so I use division.

great job, great instruction, BOOP, I especially like watching how you use GHS, i'm going to give it a try again.

[@Mr77pro]

Great vid!! Russ Croman did a repository for the CUDA crap. A no hassle deal now!!!

[@Alan-vk6bk]

Nice to see you back Steve. Great image btw 👍😎

[@enteringintospace4685]

Thanks!

My orion 250mm, I was able to grab a machined spider for 130 bucks so quite a bit cheaper than Backyard Universe offering. Something you might consider in the future. I should be up n running in a few days for some testing... Great video man.

[@enteringintospace4685]

Cool! Where did you get the new spider from?

[@qx3V45p]

@@enteringintospace4685 Bought it from a guy on Ali Express. It's sold as a spider for skywatcher OTA's but the seller was very responsive in sending all the measurements so I could determine if it will fit the Orion. Very cool guy. I can email you the info if you'd like.

[@DSOImager]

Nice shot! That scope/camera combo is working well. CS!

[@enteringintospace4685]

Definitely is! Thanks!

[@newzerozeroone]

I probably missed it. Was that 16 per filter or 16 hours total?

[@enteringintospace4685]

No 16 hrs of just ha, 10 hrs of lum and 4 hrs of rgb

[@cenkertunaboylu]

I was not happy with result of the red channel and Ha combinations this could be a better solution thank you

[@qx3V45p]

I commented twice to your question about the spider and for some reason it's not showing up. Sent you an email

[@enteringintospace4685]

That is weird, must be the northern lights interfering with our transmission...lol. Thanks!

[@ErikStitt]

Yes, it IS really cool.........and I thought I heard you snivel.........just a tiny bit. I'm over it.
