This is the best description I've heard for aligning my telescope! The instructions and even other things I've found online have been so confusing, but doing it during the day is genius!
i'm kind of a beginner myself and i found it very usefull for dimming down objects that are very bright, like the moon or jupiter. on a smaller scope i may use it for increasing the f-stop, when using it on a camera like a lens.
OK, Robert - question pertaining to the lens caps on the aperture: What is the reason for having the two caps? I've heard that it's to intentionally allow LESS light into the scope for various situations. Care to elaborate on that, please?
pigslefats and Lovre Alviž Thanks for your questions. You will often see people have a stab at answering this question: it’s to help collimation, allow a solar filter to be fitted, allow steadier observations to be made during bad seeing etc. All quite imaginative really - and all quite wrong. At least ‘wrong’ with reference to the manufacturer’s knowledge. The answer is actually quite simple. It is a feature copied and recopied by a multitude of Chinese fabricator’s 20 years ago all of which had no idea why it was like this but the Japanese original they examined had it so they copied it. The Japanese, in turn, copied the scope from a European or US original 40 years ago - so they don’t know why they did it either. The original telescope was made by people who understood every aspect of their product and the astronomical culture it was a part of - and they had a mundane reason for the double cap (probably one of the reasons already mentioned above). But sadly they are gone - so we can’t ask them why they did it. Politicians think it’s a great idea to have poor people far away make cheap goods for us. Personally I find the spectacle of people designing machines and not knowing what parts of them are for more than a little unsettling. But then, I’m not politician. KR RJD A&NTV
I have a 130mm reflector which has the dual cap (one of the caps is offset) I played around with it one night and it seemed to ever-so-slightly dull the intensity of the image when only the small cap was off. I guess this could help a little with viewing brighter objects. I doubt this is what it's original use was for, but it's all I could think of.
They are okay those mount for beginners are cool best thing to do is got a dealers and ask them to demo it you will soon realise that what you want and what you get are two different sides of your bank account dont buy one until you have a plan of what you want to do with it if you doing this for fun yeah by all means go buy a cheap one that will end up in the shed or garage rusting in 6 months time if your serous and want to do this as a hobby and get into deep space photography dont be surprised at a grands worth of scope and mount and that is just the basics the rest can set you back as much as another 2 grand in equipment this hobby is not for the faint hearted or people who want to die with there cash rendering it award to the government if you dont make a will to gift it other wise enjoy your life spend that well earned cash on something that will make your dreams come true when you look into the the vast wonders of this tiny universe we all live in

thank you! finally advice for how to use the finderscope! keep going like this guys!
i'm kind of a beginner myself and i found it very usefull for dimming down objects that are very bright, like the moon or jupiter.
on a smaller scope i may use it for increasing the f-stop, when using it on a camera like a lens.
"get it set on a window of a house" ..... I swear officer I was aligning my finder scope. Still you guys do great videos, keep it up !
Just got a new telescope and this was very helpful. Thanks, A new subscriber too!
Really helpul and informative guy.Thanks for making great understandable videos.
I am seriously thinking of coming to you for a new telescope now :)
For the Newtonian telescope smaller caps helps you the check allignment mirrors of your telescope. I dont know use on refractor telescope.
Good description for beginners
Excellent tips!
This is helpful.
It stops down the aperture, makes it easier to see the moon without blinding yourself.
All great vids!
Viewing very bright objects, like the moon.
Large apertures can make the Moon the equivalent to staring into the sun
I can relate. I have an 8 inch telescope, and I literally have to use sunglasses since I lost my moon filter.
at 2:54 is that a 250mm skywatcher on anNEQ6??? looks awesome!!
OK, Robert - question pertaining to the lens caps on the aperture:
What is the reason for having the two caps? I've heard that it's to intentionally allow LESS light into the scope for various situations. Care to elaborate on that, please?
What IS the point of the smaller central cap, exactly?
Love you guys
The cap that you can remove as shown around 1min 45secs, is that so you can add some solar film to have a solar filter?
Can I ask where I can get one of your Eq6 piers from. I can't seem to find them easy. Thanks
That cap why does it has two peaces.
so if you must remove both caps, why bother having two?

"Tiny universe" wat???
Beautiful comments!
Someone in my town has one of those white domes that telescopes are in,
Sounds like you need to make a new friend.
