I saw some photos from your 6 inch f/8 mirror those photos are very sharp and vivid in colour but how can this possible to achieve such quality without aluminizing or silvering how only a transparent piece of glass produces images so clear
That is because my mirror's quality is very high 1/17 wave around. Aluminizing or silvering has nothing to do with the quality of the mirror. It only helps increase light reflection. An uncoated mirror reflects around 4% of light so you can see the objects and assess the mirror's quality before coating it. Coating is just a few angstroms thick layer of aluminium or silver deposited on the curve of the mirror.
You can certainly make a secondary mirror yourself but it's a time consuming job so people usually prefer buying it. You can buy the secondary mirror from me. Please check this page of my website khanresearchindia.wordpress.com/secondary-mirror/
There are many however please note that most of the books written are old and do not reflect the current advancements except mirror making which has been basic over the years. I am listing below the books I have read. 1. Standard Handbook of Telescope Making by N E Howard. Good first book to read about the telescope making. 2. Homebuilt Reflector Telescope by Sam Brown. It's a shortcut book about telescope making and is a short version of the book All About Telescope by same author. 3. How to make a Telescope by Jean Texereau. This book was and still the Bible to many. Please note not everything is simple to read in this book. Build Your Own Telescope by Richard Berry is the most recent book published about telescope making. I don't have a copy though. If you want only one book then I would suggest buying this book only.
@@astrokhan actually I am totally beginner and earlier I don't even know what are ronchi and foucault test used for but now I found a website from where I can find what are these tests but didn't find what are zones so can you tell me what are zones used for and I am planning to make a 8 inch f/6 mirror
@@bangtan_armygirl7 Zones on the mirrors are primarily the defects which you need to correct before calling the mirror done. Zones are deviations from the desired curve and could be high and low areas of different RoC. I suggest you read some good literature to understand about the zones.

Should we need to make grooves in tile tool
Not required initially since course grits will abrade the cement below the tiles level. Only on finer grits make groves around a mm deep if required
And also tell me from where you purchase your secondary mirror or can we make our own

@@astrokhan thanks for this generous suggestion
Hey man I think I can get much information from you about telescope making in a easy way so can I get your w.t. no.
Can you tell me what are zones in telescope mirror
Sure. Send me a pic of your mirror's Foucault testing and I will let you know.
