This is part 2 of my tutorial on how to make an 8 inch reflector telescope. In part 1 I showed you how to make the OTA or optical tube assembly (The red tube part). In this part of the tutorial we make the mount that holds it (The blue part).
This is a unique and very effective design I call “The Cabinet Mount” telescope because it is also a small cabinet that will hold your various telescope and astronomy things like eyepieces, barlow lenses, astronomy magazines and anything else. It keeps it all organized and in one place for you.
You don’t need any particular skills to make this telescope mount. Just some simple tools, some wood and a few other parts. I explain to you exactly what you need and how to do it.
Wonderful little telescope that is portable, easy to use and easy to make. I like it! It is the Cabinet Mount Telescope!
The main bearing that rotates the telescope is called a lazy susan and it is readily available in many styles. The one I use is sturdy and cost me around eleven dollars. The white things you see that the telescope moves up and down on are simple pvc pipe fittings you can buy at the home depot or Lowes.

Plz show us how this works ???how the night sky looks through this
This is a great suggestion. Thanks! I am planning on doing a video with pictures. Maybe even a live stream. It's a pretty powerful telescope! Jupiter, Saturn, The moon and more are great with this telescope.
All of us are waiting thanks
curious if it really works well. No pictures to see.
@@epicfantasy how to use means if we want to see jupiter than how can we get focus?
@@rishabharyan613 wouldnt it be near impossible without motorization and sky tracking?
can you please show us how saturn and jupiter looks through ur telescope?
Cool tutorial.
One thing that would have been good to mention is the importance of having a dust cover over the end of the tube whenever the telescope is not being used
Wow, great comment and thanks! I have pinned this comment to the top. A few days ago I was thinking about making a dust cover and adding it to the tutorial. Then I forgot all about it! Thanks for reminding me.
This is such a simple idea - the cabinet-mounted Dobsonian! - that it is sheer genius. Great idea; great design. Thank you for such an inspirational video.
Love that it can be put away so easy.
I have a special giveaway bonus for this video. If you make this telescope send me a picture. I will mail you a copy of my new telescope book free. Limited to the first five people.
epicfantasy does it really work??
Wow
would love to see how good it works
I'm an Astronomy college student, I have a project for my major, I need to make a telescope, but I don't know where to buy 8 inch concave mirror. I ask mirror shops in my city but they only have convex mirror. I only have $10 budget to buy one concave mirror. (sounds crazy).
How much total did this cost because i am currently building it off of your specs. The cabinet and everything I'm trying to find cheapest way to build it but with quality stuff.
Watching part one and this video made me happy, I thank you for your tutorials and the attitude you have. Definately gained a new sub, great content :)
Great work!
Nice to come back to your channel from time to time.
Thanks for orbiting in once in a while. I officially name you comet Red Rose :)
Very clear explanation of how to make a simple scope. For anyone contemplating this I would say the secondary mount looks very simple with no ability for adjustment. That makes construction easy but could cause issues unless you get it right first time. The legendary late John Dobson did similar using shims of wood so it must be possible if you are patient. Using this method and at ~f3.6 such a scope would be OK for wide field views of star fields, perhaps bigger nebulae and galaxy hunting but certainly not planetary observation. Love the under scope cupboard for accessories, that's very handy.
Awesome stuff Bud !!
Great work
Nice video thanks sir
Again, nice job - very fun project, and i love your intro! Funny, and fun. Good stuff. :D
Love this! I like the way you made the side bearing tensionable with those shims to get the right movement up and down. Do you think there would be a way to add something similar to keep the lazy susan part from moving too easily? Great project, and I think I know what I'm making next - 6" mirror set already here!
Superb Dear thank you for sharing 🙏😀🎉🎉🎉🎉🎉
Nice ...
Well this is pretty much useless if you dont even show a video with the telescope viewing the sky
Thanks for great video. The telescope works great. Only modification I made was to make main mirror quick release. Mirror sores in a box when not in use or in transit and easier to keep clean. Just slotted holes in tube to edge and locks in with wing nuts. Surprisingly good pictures when using telescope with digital camera. It really good for this. Now built a 14" one but the 8" a solid backup with camera. Love it.!
Great to hear from a fellow telescope maker. You should send me pics of your telescopes, for my website!
Hey andrew can I see some pictures that you took please? I want to make sure itll work before I invest in building one myself
ha ha space for snacks some cans of cola , Toilet Paper in case you're in the middle of nowhere
Where can I see pictures of how it looks through this telescope?
any videos or pictures of using it?
Good Jobs.
I'm starting to make my 6" telescope but it has a much longer tube, about 48". Can this mount be adapted to this type of tube? Any additional tips? Thank you. Greetings from Colombia.
I really wonder how heavy is the mount. Would it be significantly slighter than an EQ mount?
how do i choose the eye piece? im planing to build a mirror but i am not sure where to get an eye piece
HELL YEAH
Please make Samurai armor please?
these videos are a good example that most people could build a reflector telescope, using optics (mirrors, focuser, eyepieces) from a telescope supplier.
However,
Those plastic tube bearings and 'lazy susan' will eventually cause you a LOT of grief, which is why Mr. Dobson chose the Teflon bearings for the scope side and base bearings, and they work the same for a 6-inch mirror or a 16-inch mirror. You can move the scope with a 1-finger push. Ball bearings are meant for high-speed rotation, not once-per-minute micro-adjustments.
The tall cabinet & mount will eventually fall over, so you need to move weight down low, use Teflon tube bearings (2 for each side) and 3 Teflon bearings to replace the lazy-susan. A doubled 3/4 ply base with 3 feet will sit well on almost any surface, so the 4-wheeled base is only good for a smooth or concrete surface.
Please move the scope away from the door, unless you want to pick it up from the floor after someone pushes the door open.
Do you have a reflex sight and/or a low power finder?
Awesome idea on the cabinet holder!!
However, I would have made the lazy-susan cradle holder part taller SO THAT WHEN you store the telescope you can point the open end down thus avoiding dust accumulation on the mirrors. I understand weight balance but there could be some type of 'seatbelt' to keep it from tipping over.
Excellent creative thinking.
ok where do we get the mirrors ? mainly the back mirror , i cant see your website , its blocked in my country , thanks in advance ...
hi, where can I buy similar mirors and others stuff than yours? Do you have any link?
Hey Will I wanted to ask if you could make thorin's oakenshield from the hobbit please.
Done for get to keep the dust out of the telescope while it is being stored
Thanks for posting these videos on how to build an 8 inch telescope. Did you purchase a Spherical or Parabolic mirror? The links you provide are for spherical which cost a third of a parabolic. I ordered your book as well. I might order a couple more for grand kids.
Good video will jeff told me about the book
Thanks! I am so happy about the book!
Can you see any planets with this?
Did you collimate in part 1?
what configuration does that eyepiece has ?? actually i want to make one like that so...
I just found this -- I can't really afford to drop lots of $$$ on an expensive telescope, so I really want to try this. Thanks for posting! Do you have any photos you've taken through the telescope or things you've observed? I would love to make this with some of our scouts.
will you make optimus prime's sword from transformers the last knight and a sword holster?
..The primary mirror is a concave one or flat? 🤔
Wahh hitayo
Very cool Wil! Have you done any observing yet? The book sounds awesome, I’ll be ordering a copy
Thanks! I haven't done any observing with this telescope yet. Just finished making it yesterday :)
epicfantasy gotcha, the weather hasn’t been conducive to sky viewing the last couple of days!
How good does it work???
good rendition of a galaxy
Won't plywood absorb moisture over time and delaminate?
what are the eye pieces?
Hi... you are doing Great work and sharing your knowledge to others. I really like your videos about Telescope. I would like to know this 8 inch mirror is Spherical or Parabolic. Kindly share the link from where i can buy the genuine mirror.
Thanks for watching! It is parabolic.
Spiral galaxy, and a nebula?
HOW GOOD CAN IT SEE SATURN?? THX.
Why are so many people asking this question ? It is going to see it as good as any other 8" dobsonian (so Yes)
He's using purchased optics , which are really good and cheap these days.
After that , it's just about how well you line them up ... which his fine tune adjustments are plenty good.
The cabinent stand is a bit of a weak point imo , that could make steady images tough , but not impossible.
So imo , I would get a mirror with a longer focal length so the support base would sit on the ground .
Guessing he has an F4 mirror ? So I would get an F6 , plus it has a higher magnification range ... Cuz me likes more X power ;) hehe
Albeit the image gets dimmer ;( ... so a shorter focal length will give you brighter images , which I guess was his choice of personal preference .
you could be my best friend if we meet togther ! great job , i love all your work
You would probably need a cover over the end of your scope to keep room dust off your mirror, in addition to keeping something from accidently damaging your mirror of your 8" telescope.
Great comment. Absolutely! I need to make a cover for it!
well done brother........but what you made in 2 part video, is it a furniture or a telescope ? if telescope than what is the look of the moon, planer or sky or bla bla bla ? instead of that you displaying us the physical structure and its facilities. after seen your 2 parts video it seems that from now we can build a demo of a telescope with furniture
Could you make a quasar saber from power rangers lost galaxy?
Shower caps will keep the dust out (until they break - lol)
Had you see any planet by using it?
Still questionning about the fact this guy didn't have a ten bucks collimation laser to show us how good the collimation was after spending hours building a telescope.
What! No equatorial mount? Thank you!
Hi Colin, Thanks for watching! You are very welcome :)
Can i put it on equatorial mount?
Yes, you surely can. You just have to make some kind of a cradle mount for the tube so it adapts to the EQ mount.
epicfantasy
I think i will design my own mount 😁
And something i just noticed
You forget to put cooling fan to the primary mirror 😅😅
Keep me posted on your telescope build! Be sure to send me pics!
Is this suitable for observing the moon or. Planets?
Yes, and much more!
Test it out
Dust cover?
I see a new guy on TH-cam
Does this guy make awesome stuff? Yes.
Does he make telescopes? Yes.
Can he make a reflector telescope? Hell Yeas!
SUBSCRIBE LE!!
Thanks for watching!
Could you please make Jason Voorhees Machete from Friday the 13th???
Galaxy and Nebula/star clust.
The first one is endromida and other one is our milkyway.
It looks great and all, but how do we know you can actually see anything with it? You need to make a video with photos of whatever it is you can see. How far can you see with it? Can you actually see Saturn? That's my first question. Great video 👍👍👍 brother.
well, I went ahead and got some materials for this because it was relatively inexpensive. I have most of the measurements and all I need to do is assemble. I'll let you know if it works out.
honestly just buy something already made for you lol
@@1theheightofparadise Did it work? I want to build one myself
@@burnt_toast_astro7180 nope, its junk.
@@TerryRGraham Building a scope rn, I have learned a lot from doing astrophotography since my previous comment.
It may be a difference in mirrors, or quality of mirror cell. Idk, I don't see why it wouldn't work
Whoops, that base peice is not 1/2, it's 1". It would be good to glue those peices before you put the screws it--makes it stronger. As for the wheels, it might be better to have two of them non-swivel. One more thing is that this needs a cover for the tube, as dust will start coating the mirror.
Almost 2yrs part 2 come
I challenge you to make Samehada (shark skin) and Kubikiribōchō (executioner's blade) from Naruto
To see captures of telescope you need to find a way to mount a proper camera on it, make it capture that same shot, lap top and much more. So maybe he will do that in some time, but it needs time.
Can you even look at the Moon ?? we don't know unless you show us it working other wise it is a decoration
hmm, looks fancy but depending on the weight of the eyepiece you'll find this concept simply doesn't work. 'wheels to roll it outside' ... that's just not going to be steady enough for someone srs about this hobby but will do if all you want is to roll it out during a BBQ to have a look at the moon.
18:30 - Spiral galaxy
18:40 - Globular cluster
where is profit?
Omg.z half the video before you get to the point 😂
sir I am kiran from middle class family from india SIR its a request please can you donate a telescope that you had made.Sir i have no budget to buy for my child.sir lpz make a kind heart thank u sir.
what's ur age
5min on the internerd shows me that I can buy a professionally made 8" reflector for what it would cost to make this amateurish thing. Why would I go to the bother and possibly fuck it up? Thanks but no thanks.
I'm making this with my 11 year old nephew as way to make him interested in engineering and astronomy. I don't think he would engage so much if I just bought the thing ready to use
What a shame you don't show any pictures. It's been 5 years and you still haven't shown a single one so it's probably god awful quality. If that's the case, that's very disingenuous, people spending money and hours of their time when they should just go on amazon and buy a $150 tabletop dobsonian.
