Hi guys! Remember me? I am the guy who was bothering you for the last 6 months while grinding, polishing and figuring 8" mirror. I finished my scope today, it still needs some minor improvements and painting.
I had a pleasure to see some breathtaking things this night, even in light polluted Chicago! I couldn't say a word for several minutes seeing the majestic Saturn with rings and moons for first time in my life, I was just bedazed, and then hurrying through the sky Jupiter for a dessert! God, I can't wait until I take my new toy to some dark sky places...
So anyway, I am proud of myself and I want to thank you for your priceless advice and support. Without you I would just throw away a mirror blank and polishing lap through a window after clueless hours of painful figuring.
I would like to thank especially Tom Simmons for hand holding and being a patient teacher; Bob Chester, William Earl, Doug Scobel , Jason Lane, Floyd Blue for great tips and support and all other guys from Astromart forum I missed. Really it's good to know that you guys are around. I hope we'll meet some day on a star party!
I attach some pics of my work.
