Great job. Nice video.
Great review! Thanks for sharing!
Dude, you’re a natural presenter-great to watch!
Were your superb images from the backyard or a dark-sky site?
Looks like a used electric pottery wheel would make the job a lot faster and easier.
Nice. What kind of bearing does the table spin on? Like a lazy susan, or skate wheels, just held up by the drill shaft or something else?
nice presentation
What size of cerium oxide are you using to polish? What is the ratio of the cerium oxide to water?
Hi my friend my name is Justin I’m carving my first mirror and watch you I have a question about the depth template how do I make one for my 6 inch lens thanks for your help
Something to note is that you donlt want the difference in diameter of tool and mirror to be too big, makes it easier to keep things uniform. Weight distribution is what makes the curve. A centered tool that's bigger than the glass will just make a flat surface. If the tool is smaller than the glass and center of mass of the tool is over the glass, it will hollow it out, and if the center of mass is outside the glass, it will round it convex
Basic but functional. 👍👁️
Come to Brazil 🎉
Could you please tell me where you got the plastic template to measure the rough curve? Is there somewhere to find this to print out?
Blackwater Skies on the surface seems great, but there is now way to put in a DSLR and telephoto lens combo to get a field of view for imaging planning, all it seems to take is telescopes which a lot of us don't have.
Riveting series of videos! You are brilliant, well spoken and teach in a way that all can understand. You will go far in life!
Hello, super super random question, but it seems like you really know what you’re talking about! Question: im making a pitch drop experiment with gugolz #55. I’m using 55 because from what I understand it is the softest pitch they sell. But from a previous persons experience, the #55 was still too thick/hard. He suggested I thin the pitch but neither of us knew how. He suggested astronomy forums since you guys are familiar with pitch. Would you have any advice on how to thin pitch? I would greatly appreciate it!
Hope you are doing well bro
Beautiful video, really very nice, congratulations for the really amazing photos
I've taken this project up for my Physics Honours. This video really helped me understand more about the process. Thanks a lot!!
I'm planning on tackling this process myself but can't find affordable glass anywhere.
how many hours of grinding? might do well to use 3d printing and arduino or something to machanize and automate the grinding process- then apply to 30 inch glass plate
Excellent narration and very knowledgable.
That is a superb explanation of how to make a pitch lap. Probably the best kept secret in astronomy. Thankyou from the UK (where it's still raining).
Great job cunt!
this is amazing work!
It's a shame you're too young to know what you're talking about. My SBIG ST-10XME was a CCD and had a QE of 85%, dark current of less than 1 electron per pixel at 0⁰ and almost non existent noise at -25⁰, had dual sensors for self guiding, a remote guide port for external guiding, adaptive optics etc. The CMOS sensors are nice, but depending on what you're doing, they are a downgrade. My st8300 (another ccd) pulls far more signal through a 3nm Ha filter than the asi1600mm... What ZWO has done is make the process easy with a fully integrated system of cameras, minipcs mounts, guides, scopes and filterwheels that all work seamlessly together, but to think that any of their cameras would outperform an STL-6303 in sensitivity or STX-16803 for overall field of view for a given scope, you're unfortunately dreaming. Yes, I have an ASI2600MC and a 294M, and I love them for what I use them for, but to boldly state that they smash CCDs as a blanket statement is pretty short sighted... Newer doesn't always mean better.
Why didnt you use your drill based grinding machine for this mirror?
Very good job!
did you make a spherical mirror or a parabolic ?
Spherical. Making a parabolic or hyperboloid mirror is much more involved, and a spherical mirror will do just fine for getting started.
Logan... A very skilled young mirror maker has that name. He made very thin 18" mirrors. Same one?
Awesome telescope! Videos like this deserve likes and subscribe even if there is no beggung for them.
Are there plans for this design?
Hey, I found these videos inspiring. Why didn't you create part 4? Is it cost, moved on, etc?
Go bigger!
I reckon Logan found a girl and decided he couldn’t be arsed to do UA-cam any more. 😂
Wow! Not sure if this channel is still active? Just a question, if we to use a blank mirror, how to determine the pitch curvature?
Could silicon be used instead of pitch? Thanks for the posts, very informative.
"for a beginner". We have very differing views on the word beginner.
I just watched the video and I felt the exact same way. He just blows by all the menus and then goes as fast as possible through the demos. You can tell Logan Nicholson had been doing it for so long that it's second nature and not remembering that you need to be slow and methodical if you're teaching beginners. I think what he did was like when someone calls and leave a voicemail with their telephone number. The person leaving the message usually says their number so fast that you need to replay the voicemail at least 5 times before you get the first 3 digits.
Can you gift me a 50mm lens . I cant afford to buy. From Pakistan
Do you apply the reflective surface at a later stage? Cause your base is just a peice of transparent glass right?
Way too fast.
Went through the whole tutorial following each step closely, only to discover that my final output image was grey with no color at all... useless.
Gee, I think I'll grow my own rubber and make some tires. Really, it's good you know how to do this and enjoy it, but this ain't for me.
I like your all video 🙏🏻❤️
Yeah, I would love to do this. All I'm missing is the glass. You can't get it anywhere.
NOT for Beginners - Can I have my 10 minutes back please.
I know I am a few years late to this. But props for using freecad. It is probably the most tooth pulling software for 3d modeling out there.
