Those mirrors are hyperbolic. Parabolic mirrors are in standard Newtonian reflectors.

I have an 10" Dobsonian Telescope and I love it!

My fingernails are sharper than that goofy obsidian knife. lol

Hi. I also bought one of these scopes. I have one question. Can you optically (not photographically) get the scope to focus sharp on a star without using any of the extension tubes?

Nice stuff!

At the end he got close to the telescope to show you the Galaxy in Orion's belt.

It was a men and black reference, yes.

Is it suitable for visual observation as well? Thank you for the answer.

thanks, a dream of many is a good telescope like that

What a great shielding ... If you want a 150 mm mirror sensitivity, you buy a telescope with a 200 mm mirror. :D

Refractors are the way to go.

Nice vid. Would you still need a coma corrector for the ritchey chretien astrographs or would that just be redundant?

RC scope would not need a coma corrector

Nice toys.

You could mount a ZWO AAP to that third finder bracket

Great video ! Sorry but I cut my twine on bales of hay under tension by cutting from the under side ! Then it cuts like a knife through butter ! Have checked the local astronomy web sale page and no heavy duty Tripods ! Though one lady sold a six inch telescope for $75.00 USD (My brother has the same model 110 VAC from a wall outlet). Thank you for the knife review ! tjl

It's possible to mount the telescope using that vixen dovetail on "top"... you don't have to use the Losmandy dovetail.

what please your x-ray geiger counter test next video......

Can't wait for future videos. P.S.: How can you use your neolithic knife without neolithic beard? :-)

Hello tom, I had contacted you some years ago via email in regards to radiation detection equipment. Hopefully you see this, I had a few more questions in regards to gamma spectroscopy. Thank you for your time!

My favourite actress is Cindy Crayford... meanwhile, I just bought a nice Crawford focuser Oh wait, other way around. ; )

I also have one of those, not used it much though to be honest. Really prefer a big refractor (NP127is for wide-field) and ODK12 (small stuff like galaxies). You realise that getting into astrophotography is going down a rabbit hole? You think the scope is the big cost? LOL! Hope you enjoy it anyway :-) PS. To get the best out of learn how to collimate an RC scope, can be tricky but easier if you have a laser providing a circular diffraction pattern.

Go BIG and get a Software Bisque mount! JK! Nice photos BTW!

That knifework was painful to watch! Only kidding around Tom.

antiprotons hey antiprotons, I was wondering what Geiger counter/radiation monitor you would recommend for someone who wants the capability to measure high levels (Sv/h) and low levels (micro sieverts/h). I ask this because most counters for sale seem to only be able to measure really low levels.

The focuser base is made from plastic.

I hope you have gotten yourself a real knife by now! 🤪

"Behold" lol

Someone send him a good sharp knife or a sharpmaker, jesus ;D But on topic: So, i bought a 8" Celestron EHD one year ago. Unfortunately i used it only three times since then and i really have to do something about that. In 80% the wheater is bad - in 2% im sick in 3% i have to deal with oder things, in 5% i am to lame to do anything after work in another 5% im to afraid to risk getting ill because i have to do my work... And then there are 5% which I HAVE TO USE FOR THIS. Oh my god, i am getting ill seeing my telescope getting dusty :-(

I think some cat hair went in the tube.

craftsman he is not.....

You’re knife could use a wet stone 🙄

Not a very cost effective set up for astrophotography. I dont like it one bit

What part of it don’t you like? The scope itself? The accessories? The mount? I mean, you don’t *need* (even a little) to use an ST80 as a guidescope but it’ll work just fine and it won’t be worse than a random 50mm achromat - and using what you already have is always cheaper than getting something new.

@@JasperJanssen um, actually he need the focal lenght (600mm) of his ST80. That 8" RC is running around 1600mm so you will get shit guiding using a 50mm guidescope.
