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?

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
@1495978707Ай бұрын
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

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.

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!

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.

Spherical. Making a parabolic or hyperboloid mirror is much more involved, and a spherical mirror will do just fine for getting started.

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.

Do you apply the reflective surface at a later stage? Cause your base is just a peice of transparent glass right?

Yup. You send it in to a business that has a chamber that vaporizes aluminium which then deposits onto the glass making it a mirror.

@1495978707Ай бұрын
Because a sphere is made of a bunch of circles. For this to work, you have to be very diligent in keeping even. The more gradual the material removal, the easier that is. It won't be perfect when you do it by hand like this, to make it perfect you have to make a machine to automate the process. The point here is that you can make a good enough mirror to get started for way easier and cheaper than a super fancy telescope. You totally can automate the lapping process, but you can also imagine how much work that would be, and a beginner needs easier quicker reward for his efforts, so he's motivated to push on
