Hi Adam,I did not know you did each video so many times. I hope it can get easier. The results are superb. I was looking at the Youtube channel to see if you were posting some subscription videos there. But they are a bit different. Thanks, Roge…

Helge,Regarding optimum subs duration, you might want to search and watch this instructional video on Youtube:Deep Sky Astrophotography With CMOS Cameras by Dr Robin Glover.You can look at his charts, estimate your background light pollution rate, a…

Adam,Great explanation, and no, I do not believe 25 x 300s good subs can be equal to 25 x 600s good subs after integration. I think your conclusion in the 3rd video that each method should be used intelligently depending on your own particular data …

I fully agree with you Casey, except (luckily) I don't feel like the girl with the thick glasses! Well written. The "Presto" crowd was the best!Our journey continues with Adam, the universe, and our individual intellects.Roger

Hi David,I just used the expression with my own values on my image after DBE (several times) and the background is definitely uniform everywhere. But to me it is too perfect. The perfect background accentuates the noise in the galaxy. I did improve…

Yes, I am smiling at your reply! And more relaxed that NGC3199 data will be included along with the videos. Roger

Hi,Is NGC3199 going to be Telescope Live data since visibly mainly from Southern Hemisphere?Roger

Hi Adam,Your promo makes the pricing quite reasonable... 2 months x $19 x 50% = $195 credits to start + 20 x 2 month = 45 credits. For 'grabbing' the 54 hours data (assuming the amount of data to grab has not increased) needs about 54 credits (incl…

Bruce, I tackled this same star with similar huge blue halo when I imaged Horsehead. The second time I was successful. I made a Game mask (as big as the blue), carefully centered it, and feathered (convolution) the outer edge. I had to be careful th…

Hi Adam,The flats are about 1 month different than the subs.Yes, ESD always has given me less than .5% rejects. Where Windsorized rejection is normally 2%+/- total pixels rejected.I know my image data is noisy, and background level higher (.10) than…

Previously I successfully used MureDenoise with my OSC, and it worked very well.So I will try it on the separate channels.

The videos and depth of discussion are outstanding! Thank you Adam. This year there have been many major improvements to PI. Every month something to download. And a new explanation video by Adam. Now I find I want to go back and reprocess all my da…

Yes, NSG is really great for setting integration weights (NWEIGHT), and helping make each background closer match the background of the chosen reference frame, where the user selects the reference frame with the least complex gradient.Amazing what 9…

Adam wrote: "If the distortions are small, likely it doesn't matter much" Juan on PI forum said distortion correction will not affect MD. Same for LPS.
-
Interesting in the same screenshot warning, he also says "and be registered by projective transformation with no distortion correction." I normally use (checked off) distortion correction during star alignment. But not sure if anything was really co…

Adam,You did clearly state at least twice that MUREDenoise should be done immediately after integration. It was my laziness to not go back to before DBE, which I based on what the video said in one little statement.Roger
-
I agree your above statement to do MUREDenoise immediately after integration. I tried it on my DBE image, and it does not work.But your video states it a little differently at 16:03 to 16:25. Following this you apply MUREDenoise and it seems logical…

Well, I was talking English subtitles. Most astro-photographers doing processing can read English. Many cannot understand it verbally.I do know an avid PI user (much better at it than me) that knows Chinese and English (verbally and written).I'm goi…

Adam,You are the master! If you load the image to Blink and don't do anything, the readout value is .70. Then do the Blink's Auto Histogram Transformation (like we always do), then the .70 stars jump up to .99! If do Screen Transfer Function on Blin…
-
After further checking. If I open an image and check a saturated star it reads .7 as discussed.If Blink the same image, the same saturated star reads .99. Both 1x1 and 2x2 data have this difference. Maybe this is some setting I have in PI is making …
