Hey folks!
This KZread channel provides basic tutorial videos for astronomy and astrophotography.
The curriculum will cover topics like
x movement of the stars in the sky
x different mount types
x telescopes to choose from
x image acquisition techniques
x post processing
x … and much more!
Step by step newcomers are guided through the complex topics of astrophotography.
Hi, I’m Chris! I am a physicist and very interested and enthusiastic about everything above us. I came across astronomy a short while ago and as I went through all the very good tutorial videos, forum discussions and helping websites I decided to create a “safe haven” for beginners. People without the time or with no idea where to start digging may here find their “starting-point” for the long journey of astronomy. This basic tutorials can only scratch the surface but shall cover everything a newcomer needs to know to get started! So join me on my ongoing journey!
Clear skies everyone!
Greetings
Chris

i really want to see this on the 13 pro max
Best,👌
Excellent work flow
Great live view of Jupiter. I am amazed at the abilities of your telescope system. Great music yoo😊
Another gadget like a robot cleaner to be stored somewhere in the house. I will buy one.
Thanks for the video. What rotation do we see here? Of the atmosphere? Does the inner ‘core’ also spin as fast as the outher (atmosphere) core?
Great video screech
amazing!! simple and useful, thanks🤟🖖
Could this be used to track Drone activity in my neighborhood. Will it track moving objects in the sky
I dont know why but stellarium on pc and on phone are giving me different places
In what circumstances? Cheers 🥂
Thanks a lot (not!). Downloaded GetPaint and got malware :(
AaaaaaaaaaaàaaaaaaaaaCvvvvv
EQ mount - at last it dawns! Thanks
If I get this comment correctly: sry for my accent, English is not my native language. Cheers 🥂
Well, 4 years later and you helped me realize that the circles with the look of small secondary mirrors all over my screen was actually stars. All I had to do was fine focus and I would have been good. Thanks! Also me from the future, you are going to love the new Astro cameras! lol!
Haha :-) happy to be of any help 😊 but i know this feeling of realizing things years after. Glad everything turned out okay!
Finally someone talking specifically about tripods not just mounts.
Plans are hot for restarting this second chapter soon. Any suggestions? Cheers 🎉
@@catchingphotons I would love to see a comparison on stability and vibration dampness of Wooden/Aluminium/CF/Steel. Same Scope/Mount/Same Magnification . The Carbon Fiber tripods are relatively new for Astro use so whether it can damp as well as wood, I have not seen a proper comparison done.
I guess this also works in the App (iPad)?
I don't think background removal on iOS version is possible. Cheers
Greay beginner video!
Thanks for your kind words!
I was looking for a Nikon P1000 until this caught my attention. Now I see that the Dwarf II only has 675mm equivalent focal length while the P1000 has 3000. Can I conclude that for use during daylight I better wait for a successor of the P1000?
I understand that the Nikon P1000 is a dedicated daylight photography DSLR like camera. This is a totally disjuncted category. The dwarf is a stationary camera, with its own strengths and weaknesses but with totally different objectives. It's like comparing motorbikes and cars. Both drive but... That's nearly all. Cheers!
@@catchingphotons The Nikon P1000 is a multi purpose superzoom bridge camera which has been used over the years in a wide variety of fields like astrophotography, birding etc. In the end its always a combination of optics sensors and software. After doing more research a spotting scope with decent camera mount may be the more appropriate solution if Nikon decides to get out of the superzoom business.
Visual observations only it is very hard to beat a 150mm F/15 Refractor on the Solar system objects At 150mm the seeing remains more stable most of the time. The visual images in my Long Focus Refractor look very nice indeed. Afocal images with an iphone 8 are very nice and no stacking of images. However what the Human Eye sees is still better the most cameras. Now days it is all about letting the camera have all the fun. Very nice presentation.
Thanks for your insights! Visual autonomy is a very rewarding field. Cheers 🥂
You know it's a shit video and someone is just regurgitating when they can't even tell you what format the location goes in lol.
Can you explain how you use the moon no as a reference to size?
Hi @derec7793! Using the moon as a reference for size in astrophotography is a handy technique. Here’s how you can do it: 1. **Understand the Moon's Apparent Size**: The moon appears about 0.5 degrees in diameter in the sky. This is roughly 30 arcminutes. 2. **Frame Your Shots**: When capturing other celestial objects, frame them so that the moon’s size gives a sense of scale. For example, if you photograph a planet, compare it to how the moon would fit in the same frame. 3. **Use Planetarium Software**: Tools like Stellarium can show you how big objects appear relative to the moon. This helps in planning your shots and understanding the scale. 4. **Post-Processing Comparison**: In your final image, you can superimpose an image of the moon taken with the same setup to illustrate the size comparison. By using these steps, you can effectively use the moon as a reference point to communicate the scale of other objects in your astrophotography.
My iPhone will not take a 360 pan. Only about 180 degrees.
Hi @SmeeUncleJoe, Your iPhone can indeed take 360-degree panoramas, but it might require a bit more effort than a single sweep. Here’s how you can achieve it: 1. **Using Pano Mode**: The default iPhone camera app has a Pano mode that typically captures around 240 degrees. To capture a full 360-degree panorama, you’ll need to take two overlapping Pano shots and stitch them together using photo editing software like Photoshop or a free alternative like GIMP [[❞]](support.apple.com/guide/iphone/take-panoramic-photos-iph7e06402b4/ios) [[❞]](www.thinglink.com/blog/step-by-step-guide-how-to-take-360-photos-with-iphone/). 2. **Third-Party Apps**: There are also several apps specifically designed for creating 360-degree panoramas. Apps like Google Street View allow you to take multiple photos and stitch them into a 360-degree image directly on your phone. Another option is the "360 Panorama" app, which uses the phone’s gyroscope to help create seamless 360-degree images [[❞]](support.apple.com/guide/iphone/take-panoramic-photos-iph7e06402b4/ios) [[❞]](www.thinglink.com/blog/step-by-step-guide-how-to-take-360-photos-with-iphone/). 3. **Stitching Photos**: If you opt for taking multiple photos manually, ensure there is a good amount of overlap between each shot. Tools like Microsoft’s Image Composite Editor or Hugin can help you stitch these images together into a seamless 360-degree panorama. By using these methods, you can create a custom background for Stellarium. If you have any more questions or need further assistance, feel free to ask!

no more videos? :(
I'm working on it. I moved and this took sadly all the time there was. Now I'm getting ready for the next round 😀
You don't point to the adjustment Laser screws, only talk about it. Also this Svbony is pre adjusted and it double glued so adjusting will be hard. FIRST check to see if when you rotate it if the laser does not stay in the center FIRST before using or adjusting the laser screws! To confirm if the Svbony or any laser, take a 2"x4" x 6" piece of wood and used 4 round head screws 2 for the front and 2 for the back of the laser laser and place the screws so they are placing the Svbony laser in the center if the laser and then when turned on point to a wall 25 feet away and see while rotating the laser that it stays in the center, maybe be take a white sheet of paper and put a circle about 1/4" and place laser wood towards the wall and turn on and tape the sheet of paper putting it in the center of the laser and then go and rotate the Svbony laser and see if the laser stays in the center. If not adjust or if you just got from Amazon return it and get another as newer generation lasers are pre adjusted? P.S I don't like how large that center hole on the laser angled scale is. Also if you find the 2" Svbony adapter or the 1.25" is a bit loose just take that scotch tape and wrap a bit fully around the metal part that goes into the EP holder and if 1 layer of tape makes it snug your done, if it's still wobbly then 1 or 2 more wrappings of tape should make it snug.
Thank you so much for your helpful comment!! Cheers!
Hi Chris, thank you so much for this tutorial ! Really helpful To avoid the same struggle I had when implementing into Stellarium : it seems the .ini file should be named "landscape.ini" exactly. If not the software will keep saying that there is no landscape in the zip file.
Great! Thank you so much for your helpful comment!!
WHAT ABOUT HTE ANGLE UP?> how do I know what the actual dec and ascension is?
Might be nice to have a power line/poe connection kit for longer runs. With long term improvements I could see attaching a retractable dome/base onto a solar install rail and help with object tracking/data gathering. Long way to go but some of the choices they made seem like that could be more viable in the next decade.
Very well explained! The visualization with the lines really helped, and the emphasis on "summer/winter/9am/10pm" haha. And now I can't see the night sky without imaging the lines across the spherical night sky!
Brilliant 👏👏
Nice video ! It makes sense but it's basically still the same with photography that the wider the aperture the more light you get (plus depth). I always like to think about aperture as just being able to see a object from different positions but mashed up in one single and so the wider the more of an objects light can be summed up.
Thanks that's definitely a way of thinking about the problem. Cheers 🥂
Possible in smartphone?
Unfortunately not.
I got the Svbony laser collimator. It has two problems. First, the movement of the screws is not enough to collimate the collimator itself. Thus the laser is always pointing at an angle no matter what I do. Second, the electrical switch is defective: I turn it into position, knock on it, and sometimes it turns on.
Oh no! Seems like a clear case for refund or replacement? Did you have any problems with that? 🤔
Thinking in terms of moon diameters is really helpful. The moon is fairly easy to photograph, and it's easy to learn what focal length/field of view corresponds to how large the moon appears.
What is name of Camera? Bramd name?
Zwo ASI 120mc
Is that the Skywatcher EQM-35 with Quattro 130pds? I just bought the same setup, literally! Am I in for trouble? Nothing but problems? I was afraid I should get a mount with heavier payload capacity.
Nice video. Thanks
You are very welcome!!
Thanks for a great video. You have a very soothing voice 😃
Haha thanks! Cheers!
the drinking parts really kills this otherwise great tutorial
Thanks! There are drink free versions available. Cheers!
👍
:-)
How much of the setup process can be handled via script? Seems like acquisition of darks, flats, etc. could all be done via a few scripts interfacing with the camera, mount, and a small Raspberry Pi.
Probably true. I tend to do things the manual way, often because I started fully manual and gradually shifted to automatic mode. But there are superb software tools out there, NINA being one of my favorite ones (open source and free).
When I was learning about spherical coordinates, I wish I would have known about telescopes: alt = theta, az = phi, focus = r. Now that I teach it, I'm going to start using a camera with zoom lens and tripod so it's immediately visible.
Great idea!! Teaching is also the best way of learning (says me as a teacher) 😄 cheers!
I have a physics degree, but surprisingly, astronomy doesn't figure much into the curriculum. I got a cheap telescope a few months ago, and now I have this intuitive sense of which way the Earth turns, and I feel connected back to historical astronomers. Can you believe that Tycho Brahe didn't even have a telescope?
I looked him up on Wikipedia. What an amazing person! Great that you found a way to reconnect with the universe, astrophotography/ astronomy is such a rich and giving hobby. Cheers!
I photograph with my phone camera Are 10-20 MP photos good?
MP does not matter so much. It all depends on the optics. Cheers!
I dont have a motor so my exposures can be only ⅒ of a second so my photo will have only a minute of exposure
Maybe you try a very simple start tracker? They'll allow you to increase the exposure time to tens of seconds and this will make all the difference. Cheers!
Dobson 10" can be motorized?
❤you said this video would be about using a laser collimator but instead you instructed how to use a collimation cap which is DON’T have!!!!!!! How frustrating!!!!!!!!!
Oh boy! 😯 Please note that you can buy a film roll for <5$€£ and then you are well equipped. I mentioned the cap because there are many many telescopes out there that are badly collimated because ONLY a laser was used. Wrong secondary alignment will cause you to badly align the primary as well using a laser and then you are out of game entirely. Cheers!
Probably the best explanation by far
Thanks so much!!
Amazing thanks !
No worries, you are very welcome!
Can this be mounted equatorially?
In principle yes. You could let it face the north star and then a rotation along the AZ axis will result in effectively being RA rotation.
