Windows 7

Windows 7 me Arduino ide 1.8.19 install nahi ho Raha hai to maina 1.8.18 Kiya usme esp 32 option hi nahi h 1.8.19 install karna k liye windows 10 mang Raha hai to mai kya karu

Esp32 ka option install karna parega , download karke ,

You can cut your own mirror blank from plate glass or you can buy it from different seller, such as India astronomy club ,Bangalore

12 inch

Where 12 v is mentioned connect with 12 v with parallel and where 5v is mentioned connect 5v with parallel .

I gave the circuit diagram in the vedio , pause the vedio and draw it .

Hi

App ko 4 wires wali stepper motor ki jarutat hogi ye mount banane ke liye.

I ordered it

And please give me a propper circuit diagram please

I gave circuit diagram in the vedio , pause the vedio and draw it

About 5000 rupees

Thanks🙏

Thank you sir 🙏

I used two worm gears for each axis . One worm gear is of 18 teeth and other is of 40 teeth .

@@astrovillager What is the diameter of small and large 3d-printed gears?

Diameter is not important , teeth number is important , you can use any diameter but teeth number must be same, anyway my plastic gears dia was 5cm and metal gears dia was 2cm

Mirror banane ka vedios deklo , mere channel me hain

Bro i used canon 1500D , all dslr are good for astrophotography ,

@@astrovillager tks bro, minimum what budget we need to spend for good dslr camera, can you suggest some models pls

Canon 3000D is the lowest budget dslr , but if your budget lower than it than you can buy a second hand dslr from Facebook marketplace or olx

@@astrovillager oh okay thank you so much for your reply

May be in future , it cost 5000 rupees

Thanks🙏

2400mm, f/8

That's incredible. Thanks again for sharing.

May be, I did not try,

@@astrovillager saya juga tertarik membuat cermin teleskop, namus saya ingin membuatnya dari cetakan semen, namun saya masih bingung dengan bagaimana caranya membuat lapisan cerminnya. sampai akhirnya saya menemukan video anda

If you want to make a telescope mirror then glass is only one option . You can't make with other materials.

Desired , not mandatory , you can put 2.5 , or 3 or 2 , I put 3 to slew my telescope little bit faster.

also where did you find the ckt diagram ? i have a 38 pin esp 32 so i needed one for mine.

My one was 30 pins, I got the circuit diagram on Internet .

No brother , autoguiding is not possible with it.

@@astrovillager Thanks for your reply ❤️❤️❤️. Not many creators respond after uploading a tutorial 👍👍👍

Thank you for your suggestion 🙏, Yes I am thinking about pvd coating , Yes, i have to invest some money, By the way you mentioned vaccuam pump, rotary vane and diffusion pump , do i need both or any one of them . Is rotary vane is enough for creating proper vaccuam? And ok i will enable my join button.

@@astrovillager both pump need . Roatary vane pump gives rough vaccum like rough grinding. Diffusion / turbomolecular (any one ) gives higher vaccum . Single rotary pump is not enough to create 10^-5 milibar of pressure. Single pump can't go beyond 10^-3 That's why we need different mechanisms two pumps. Aluminum matel vaporizing temperature is 2100 C in air but as much higher vaccum is boils faster , In higher vaccum it could boil just on 800 to 1000 degree . But we directly can't use higher vaccum pump. Ex-: It would be like to rough grinding mirror cerium oxide . Think how difficult is to .

OMG, Yet I will try in near future . I see the rotary vane pump available on amazon ,can we add 2 or 3 rotary vane pump in series instead of diffusion pump ? I watched a youtube vedio of pvd . They used only a oil diffusion pump .

Actually very less detailed video available on KZfaq about Pvd Let's we know everything in detail. Reason 1. Rotary pump comes In two type : single and double stage Double stage pump is just as your idea , this pump is also included two pump in series in single motor . But these type of pupmp work on rotary and compression mechnism so , they are limited by their physical working principle . Over 90 to 95% vaccume in the chamber the air Density goes very thin and this roatary mechanism can't suck air any more . Ex: its holding water on FORK spoon .as same struggle face by this rotary machine when its pressure goes around 10 ^-3milibars . So If You Add 2,3,4.... in series but also can't suck air by its limite due to extem thin density of air(like Fork spoon example 2,3 or .... over and over spoon can't hold water more then its maximum surface). Reason2. When we add Diffusion oil pump its trap the air and throw out by first pump (rotary) May you think what is special khichri😅 in this Diffusion pump? Diffusion is a type of balancing process of air pressure . But here diffusion is an oil Boiler heater which heats the heavy Oil mineral oil (silicon oil) and creates a fountain hot boiling oil , this boiling oil actually cause to trap the air Due to heavy weight it's down in the bottom and light air passes by its exit pipe hole This exit hole is connect with first pump intake and then rotary pump throw air out . Diffusion is work like a transformer/air density dopper If you want its diagram of whole circuit gives your contact like what's app or instagram Diffusion or turbo molecular pump is a like Steriod of BODYBUILDER/ Vacuum builder 😅😅. Turbo pump is expensive then diffusion , and more complicated to repair Diffusion pump is non unmistakable because it has non moving or rotating part. I hope you 20% doubt clear🎉. For more info ask me any time . Thanks🙏🏻🙏🏻 for complete reading.

Thanks for valuable writings 🙏, Please give me the whole diagram , My whatsapp no is 9862007890

You have to use nema 17 stepper motor

Approx 5kg

Onstep calculation software (spreadsheet)

Ok , I will try ,, but you can watch this vedio . I captured it with my 8 inch dob telescope . vedio link 👇👇 kzfaq.info/get/bejne/Z7xhorKC0LaoXWg.html

@@astrovillager Yes I see that is good but you can do better by stacking and processing because your raw footage is so good it gives so much detail of craters.

Thanks🙏

May be , but i used onstep ,

Yes, i made it using onstep

@@astrovillager Is their any difference or upgrade between Onstep and Onstep X.

0.58 arc-sec

@@astrovillager Thanks

Yes , why not , but keep focal length 5 to 6 feet max , to use the telescope comfortablly.
