There is no need to illuminate the telescope to view the moon, etc

Yes.

@@jayendradani3572 Thank you😊

@@planetofmystery4787 Yes, you are right. I Just wanted to make it as simple as possible. For watching during night, doesn't make much difference. But painting black inside is always better.

For getting 16x magnification, with the current objective lens, eyepiece focal length needed is 700/16 = 43.75mm to be exact

But with the 25mm eyepiece used in this video, we already get 700/25 = 28x magnification.

Thanks

But the problem is that I have a 16X microscope eyepiece And I don't know it's focal length. I don't know if the focal length of 16X eyepiece of microscope would be 43.75. Because it's a microscope eyepiece and it may have its power calibration on it according to the microscope objective lens. Can you tell me if it's focal length would be exactly 43.75?

😊

Thank you🥰

Hi... please watch the video in 0.75x speed without music if you feel its very fast....

Yes..

@@VinKrishSolutions Thank you

Thank you😊

@@VinKrishSolutions you're welcome 🤗

Yes, definitely👍👍

Hi... I have used achromatic objective lens which reduces chromatic aberration.

The lenses are bought from anand traders. The purchase link is given in the video description. Pipes are bought from a local hardware shop.

Outer diameter

Hi... did you mean template?

Hi... for seeing planets, eyepiece with lower focal length eg. 8mm will be required.

Hi...Sorry... it's difficult for me to make on personal orders for the time being...

Thank you🥰

This is mobile tripod bought from a local store..

I couldn't translate this properly. But I hope you liked the video. Thank you.

This was made just as a demonstration of how dudeney's dissection works.

@VinKrishSolutions The midpoints of the sides forming the apex of the triangle are not positioned directly above the points on the base, as you have described. If you are going to all this trouble, I think it should be mathematically sound.

Not that hard.... watch video fully and try again. You will definitely get it flapping....👍

The photo is taken through this telescope using a good camera.

For bird photography, a camera with optical zoom will be better...

Thank you😊

The total length of telescope (lens to lens distance) should be the sum of the focal lengths of the 2 lenses.

Details of lenses used are given in the full video and video description.

Yes. I am from India.

🥰

Thank you 😊 You may use the same telescope for using 4mm eyepiece also.... Since eyepiece focal length decreases, the total length of telescope will reduce from 725mm to 704mm. There is provision for length adjustment.

Thank you 😊. Seeing with naked eye is always better than with phone. For watching space, this may not be useful.

It actually works I have made 5feet dobsonian my self learn something then only comment on someone effort

Please contact the phone numbers given in video description for the detailed current timings...
