This has been know for a very long time… I’m not sure why the 60 second sub myth keeps propagating… you will definitely capture more with 1 ten minute sub than ten 60 second subs the signal is just to close to the noise in short exposures

Hi, great video! I've tried processing a few comets myself using the same technique as you but the one thing I can't seem to figure out is how you get rid of the star streaks within the tail and coma of the comet. Its driving me nuts! I've tried masking just the streaks and playing around with various adjustments to reduce their brightness and whatnot but it never comes out smooth and undetectable. I would love any tips you might have or even a video dedicated to this one aspect of comet processing. A video like this now would be great for your channel as many people are attempting to capture C/2022 E3 (ZTF)!

You should compare 4 stacked 1 minute image to the 4 minute image. If the 1 minute image overwhelms your cameras read noise and exceed the recommended Min Sub exposure time for your sky background, you won’t see much (if any ) difference in a 4x60 vs 1x240 as far a S/N and detail goes

I'm an AP beginner, but your method just seems so wrong to me. The way I have learned (which works very well) is to; 1) Stretch the image in PS initally 2) Run the image through Starnet (free software) to create a starless background image 3) Take the starless image into PS, apply dust and scratch filter to smooth it. 4) In the original image, use Apply Image using the starless / filtered image with subtract setting, use about 30 offset. 5) Bingo - almost a perfect flat image without any additional cost
@CrazedConceptions
@CrazedConceptions Жыл бұрын
I know the approach you are suggesting, but it's flawed in the sense that it will never work fully, unless you stop stretching at that point, which means that you won't have revealed everything that's in the image. If you perform non-linear stretches (which is essentially every stretch in Photoshop), you inherently incorporate the gradients in the image, which will always lead to a flawed result. If you are imaging the brightest objects and/or aren't going for very faint details it might work. But once you start going deeper, the method you described will very quickly reach its limits. A proper LP/Gradient subtraction will always take place during the linear processing stage.

Just look into Roger Glover videos and find out optimal exposure depending on scope, camera, filter and importantly bortle of site. Darker site longer exposures are needed and much better pictures comes out. Shooting hydrogen for 1min is just outright wrong even from bortle 9. Bottom line, watch Glover’s video and stop discovering bike in your videos.

I've done a lot of experimenting with exposure times and I can honestly say that I have found that the benefits of shorter expsosures massively outweigh longer exposures. Of course - obvioulsy - if we're talking about *one* exposure, a longer exposure is better than a shorter one. But if we're talking about whether it's better to take 60 x 1 minute exposures or 15 x 4 minute exposures - it's a no brainer. Shorter exposures and more of them are always better. By doing that, any photobombing due to planes, satellites, UAPs, etc are all much lessened. Wind issues are alos minimised. At 60 seconds, most mounts can track _unguided_ . Of course, we are fed the line that everyone needs a guide camera, but that's because it's big $$$ to sell them. They are honestly not needed, and neither are exposures of more than a minute or even 45 seconds. People get sucked into believing that guiding and longer exposures are necessary but the truth is that they're not.

Wrong. I don't understand why people keep repeating this nonsense. I mean, it would make sense in a perfect world(perfect uniform background signal with no LP, or other sources of noise), with a perfect camera(perfect quantum efficiency and no noise), but neither the world nor our equipment is, nor will ever be - perfect. You want faint stuff? You go long exposure. Not even a billion subs will reveal the faint stuff in a stack if the individual sub doesn't get enough photons for whatever you wanna resolve to get above the combined noise floor, and the camera is not the only source of it. And even in a straight apples to apples comparison - short sub stack loses in SNR department. Longer subs increase SNR linearly, while increasing the total exposure length merely doubles it, whenever you QUADRUPLE the exposure time. So, for example: a 4x240s will have twice the SNR of a 16x60s stack.

I thought you gave a great presentation with very helpful & practical tips. The only downside for me was that it was really hard - virtually impossible - to tell which image you were referring to at any one time IE whether you were referring to the 60 second image or 240 second image on the screen...... Maybe next time label your images clearly so we can tell which images you are discussing. Thanks again for an otherwise very helpful video.

@CrazedConceptions
@CrazedConceptions 2 жыл бұрын
In APP the only tool you can use is LPC. It's fairly straight forward and often produces great results. In PI you can use a bunch of tasks, but DBE is the one that will give you the most control. I found that ABE with a very low function degree (1/2) can remove annoying soft gradients, but most of the times 2-3 iterations of DBE does the trick :)

Julian, I really appreciate your tutorials as I keep trying to improve my APP-PS workflow. I think this might be the year to try Pixinsight...but that will depend on how much time life allows me to spend on this hobby. A question for you - how does your workflow change when dealing with faint structures throughout the FOV? I've had two recent images (M45 with surrounding IFN and the M36/M38 area with lots of faint Ha nebulosity) that I found difficult to work with in APP. There are good methods in Photoshop, as you've shown in another tutorial, to bring out those details, but I'm curious to know how that fits into a larger workflow. Looking forward to more of your content!

@CrazedConceptions 2 жыл бұрын
Hi Matthew! If you want to go after faint stuff, I can absolutely recommend PI. In my experience, you need very good data and very good noise control skills in order to reallly bring out a lot of faint data. And PixInsight excels at noise control. Being able to adjust the noise levels on different scales of the image is a complete gamechanger for me. But it is a complicated process and I dont think that there is a single workflow for all images. You start off by doing proper pre-processing and from that point onwards, you have to check what works. This kind of stuff is highly dependant on the individual data set, that's why there is no universal rule. In that case, a one on one tutorial would probably be the best to really focus on the data set at hand. I'll be releasing more content focused toward faint structures in the future! :)

My CCD camara requires me to take longer exposures to get to my calculated Mean ADU- That is what basically tells you how long of an exposures you can optimumly concidering sky limitations of course. I must say the long exposures are worth it. And that's why I invested in a CEM60EC mount. The encoder allows me to take longer exposures in the guide camara (like 5 seconds) without affecting the tracking. And therefor I can take 15-20 or even 30 minutes exposures.. That's why they say the most important part of the rig in imaging is the mount. That said now a days CMOS chips have low read noise and can reach the Mean ADU without needing such long exposures. Great video though. Cheers!!!
