The best explanations I have ever heard! Many thanks for the clear and detailed informations!

Wido you just answered every question I've always wanted to ask and some I didn't think of. Well done. Hoping your lock down ends soon. I appreciate the time you take to enlight us all in the hobby. Clear skies!

I really like this channel. We actually get information. You’re not just showing off expensive equipment

Thanks for compiling and answering those questions, great informations there 👍

Very informative. Thank you!

Very cool!

Duidelijk verhaal en vol met nuttige info! Dankjewel!

Your video covers all the details needed for Astrophotography. Great job. Excellent photo of the Heart nebula behind you. ❤

Happy New Year to you 2 Wido, and thanks for all the Info...With your input i have purchased a Celestron 8HD Scope with the Sky-Watcher Az-EQ-6 for a mount. i already have a Cannon 80D that i am going to try and use for some astrophotography...Will let you know how this part goes! And thanks again for sharing your knowledge and time with us.

Hi Wido. Fantastic video. FYI. Most phones now a days do not block IR. Easy way to check is by recording/snapping a photo while pressing your TV remote facing the lens. If you can see the light from the remote on your camera then IR is not blocked. I read it on Cloudynights about 2 years ago when i astro modded my DSLR. Mind blowing i know:) At least it does not block the wavelength used in IR transmitters that exist within day to day electronics. how much IR comes through from distant objects i cannot say. Another mention is to your pixel scale. Explained perfectly. however i think guys that are new to the hobby should know that shorter focal lengths are less effected by over sampling. Like a asi294mc pro on an 80mm with a focal length of 400mm. Obviously this goes into the category of wide field. Keep the fantastic content flowing. You are a massive influence to this hobby

Not entirely sure why, but I just get happy everytime I see a video of yours!

This was an amazing video. You provided details that are often ignored by others. Thank you so much!

Great video. Thank you.

Thanks for your Video and happy New Year. So many clouds in germany... 😪

Nice new video and all the best for you and the family in 2022. And hopefully it comes quickly “clear sky’s “ because the last months are 🤬 Grtz Django 😎

Most DSLR or CLS do not cool the sensor but those more oriented towards video have heat sinks that are rather effective. Most will shoot video for short clips - and then there are those that can shoot video for hours without tingeing magenta.

Hi Waldo, I appreciate what you are teaching in this video and think that's fantastic! However; I would like to point out some things you could have said, especially for people who have low astrophotography budgets. #1. You can take some pretty cool pictures of DSO's with planetary cameras like my ZWO ASI 120 MC-S. I've captured images of stars and open star clusters with it, and bright nebulas like Orion Nebula with mine. #2. You don't necessarily HAVE TO have a telescope with an EQ mount. Of course those types of mounts are awesome; and when you have the $ to afford to get a motorized mount, it will greatly improve the quality of your images, but it's not necessarily a must. #3. You don't have to have telescopes with large aperture or long focal length. I've taken some pretty cool pics of the Pleiades and Beehive Clusters using a Celestron "Travel Scope" 70 x 400 mm! This compact scope sits on a flimsy Alt/AZ mount and poor excuse for a tripod, and yet; if you figure out how to find objects it works just fine. I was able to find 13 Messier objects, eight (8) in the constellation of Sagittarius (which sits in the middle of the Milky Way galaxy in the summertime) including M-6, M-8 (star cluster located in the center of the "Lagoon Nebula") and several others. All with this small "kids toy." Yes you can have lots of "hot pixels" in your images, but some good post processing (using darks and flats) will get rid of a lot of them, and other apps like GIMP and Pixinsight, etc.... can also help eliminate "noise" and create some nice photos. The quality of these pictures increases if you can upgrade to a scope and mount that is motorized and computerized and something like my Celestron Nexstar 4SE can be used in ALT/AZ mount and capture open clusters, and the computerized "go to" feature after doing a three star alignment, can make finding objects a lot easier, and short 2 to 5 sec exposures (stacking just a few images) can bring out more stars in these open clusters. Like so many "youtubers"; your video applies mostly to those who can afford $5,000 to $10,000 worth of equipment. For those of us with lower budgets, something needs to be said. We are NOT all a lost cause!

Hello Sir, I have a celestron deluxe 80eq with D80F900. I plan to use a 0.5 reducer a uhc light pollution filtter with mirrorless sony nex 5 with max iso of 64000 and max exposure time of 30s. Are they going to fit well with my telescope? Thank your for the answer, wish you have many lucks in life.

excellent video

You have improved on your english pronunciation! Well done

Good overview. In fact your 10th question has me checking my set up. With my current camera, the ASI78MC I have a tiny pixel size of 2.40um which results in a 0.35 arc-seconds per pixel resolution (C8 EdgeHD with reducer for about 1400mm focal length). So that’s way over-sampled and the reason why stars are bloated I think. I’m thinking of getting the ASI533MC Cooled. But even that has 3.76 um pixels and results in 0.55 arc-seconds/pixel resolution. Perhaps 2x2 binning would help as this would effectively double the camera pixel size (and double the angular resolution). What do you think?

I want to take pics of the planets and moon. I need a 2000mm focal length (or longer) telescope? Will I also need to buy an observatory to put that in, and where can I find a good one that's cheap? Thanks, GREAT VIDEO

Great video, thanks! I'm planning to buy a camera but, my telescope is a Meade ETX125 1900mm focal length. So, based on the rule you explain (pixel size/focal length *206,265), I don't know how to avoid the issue of oversampling, because the max pixel size in ZWO camerasis 9 µm, and even this high value (usually not recommended) result in a value below 1. What camera will match better with my telescope? Thanks

By Equatorial Telescope, do you mean a powered mount? I'm fairly new to astrophotography but I know that I can only get a few seconds of exposure/video on my non-powered mount before star trailing occurs?

Totally off topic Wido but I assume you're using some kind of teleprompter? Can you tell me what and how? The reason I ask is that, if you are, then your placement of whatever you're using is excellent because it is difficult to discern unless you are looking for it.

Sir can Canon rebel t7 is compatible for Astrophotography tool software?

Is that a celestron slt 102 on that Avx mount in your video?

Hi Wido. Another Great Video. I have a QHY 268C and I get a 0.55 arc second using my 8" Edge HD with the 70% reducer. Not exactly what I like. But the stars don't appear to be getting to bloated. But I will pay more attention now. I'm looking into another camera that has a larger pixel size. But they are running close to $4K USD. Ouch! When using my Hyperstar, I get 1.99 Arc Seconds. So from one extreme to the next. But the images with my Hyperstar are excellent. It's almost like cheating with the Hyperstar. ;o)

I'm still trying to understand eyepiece cameras as I recently got one with a 2mp sony sensor which is great at the planets but not so good at fitting in star clusters iv found that using a 2mp camera is around around the same as using 3/3.5mm eyepiece so even in my 400mm length telescope im still well over 100x wich is very annoying and I could use a reducer but then the focal length would be very short wich is also not the best thing 🤷‍♂️ I have a dslr but then that isn't the best because of the problems u mentioned but I can fit it the hole thing in and a lot more 🤣 and getting a higher pixel camera have their problems too with the tracking so what sort of pixel camera is a really the good all rounder 8mp 🤷‍♂️ or more if I keep going the way I am il have 10 cameras 🤣 just want to know what would think 🤔

I have never tried but am wondering if Anyone has used the slow motion feature on an iPhone to capture more fps in the same time? (60 fps vs 240fps). It could essentially quadruple your efforts of capture data on planetary imaging in the same amount of time. Not that an iPhone will render the best images, more just curiosity.

About astrophotography under a light-polluted sky, I might name YT channel "Cuiv, The Lazy Geek". Tokio is not known for having a dark sky ...

Fun fact : my phone has IR pass
