Telescope mirror cleaning (and re-marking the center)

[@emuhead]

The sloth backpedal is hilarious. Helpful video, thanks. 👍

[@BBROPHOTO]

absolutely tickled me 😂

I’d like to know more about how you made the fan. It appears you also move the primary mirror further in? I have an xt8, and have heard Orion doesn’t Offer a fan anymore

I bought a carbon fiber sheet, 2mm thick, and used my jigsaw with a blade made for cutting carbon fiber. I than drilled a small hole for a 5.5mm DC-plug and mounted that as well. The carbon fiber sheet is attached with magnets to some regular 90 degree angle fittings which is bolted to the inside of the telescope tube. I did mounted my mirror further in, as when i recorded this video had an focuser with a too long draw tube. I now have the correct focuser (1,5" version) and have the mirror mounted in the middle position as it should be. /Daniel

Oh My God! Your telescope mirror has written quartz in our Chinese! nice mirror!

[@ExoPhotography1]

Well, I hope it is good, but i don't have any mirror to compare with as this is my first reflector telescope :) /Daniel

Where can i get a center mark for my orion sky quest xt8 plus i only use amazon to but all the stuff i see (btw i live in puerto rici and bought my telescope on amazon) and the original center mark thah my orion telescope has its has half the circle please help me to get a new center mark 😅😂 (sorry if you dindt understand me my english isnt that good)

[@ExoPhotography1]

I searched on Amazon (i do not use amazon my self that much) but could not find anything as you say - maybe ordering directly from catseye collimation is an option? (US) The have several different kinds of center marks (i use white hotspot) If you order - also order the templete for mounting the mark. /Daniel

Thank you for uploading. I got the chance to see a rocket launch in 2018. Memorable experience. I shared a pretty cool video of the journey to my channel.

[@ExoPhotography1]

My pleasure =) wow, that must have been cool, have to check that out!

I attempted to clean a mirror using what I thought was acetone. It turned out to be nail polish remover and contained lanolin in addition to the acetone. Removing the lanolin is maddingly difficult.

[@ExoPhotography1]

I have made that blunder my self, not on a mirror but nail polish can be really tricky some times. Isopropyl alcohol is the best for optics, nothing but pure alcohol :)

@@ExoPhotography1 AGREE! I was going to suggest that but you've got it. Have a GREAT day, Neighbor!

[@bobf3598]

If you have a 3d printer you can make a template to fit snug to the primary circumference without the need for steady hands and a sheet of clear film guide. I made one for my measly 5" primary and took no more than a minute to center it.

[@ExoPhotography1]

Good idea! I’ll have to source a huge 3D-printer though ;)

[@shanegraham6318]

Great video, purchased the catseye and going to try to add the hotspot to my scope. What song was that when you removed the mirror from the scope?

[@ExoPhotography1]

You won't be dissapointed with that type of collimation, i can asure you :) I can't remember what song it is, it was included with Filmora editing software, but I am using Adobe now and have uninstalled filmora :/

[@taair6270]

Great vide but The template you used seems quite complicated to line up IMO I just drew a circle the same diameter as my primary and cut out a cardboard template with an exact small hole in the middle and stuck a small self adhesive paper blank on the mirror using the template as a guide. simple no problem works fine. and because I used a thick piece of cardboard the template didn’t touch the main mirror surface.

[@ExoPhotography1]

That sounds like a neat sulotion! It is how ever quite easy to line up, no hassle at all, but is performed best with two persons for sure =)

[@erichall9907]

great video, ship the music next time

[@rageofyouth569]

Love from India Kolkata...just sub u...I just got a Astor master 130eq...plzzz can u suggest me some beginner scope camera

[@ExoPhotography1]

Hi, well, if you wan't to image planets - I would suggest a ZWO 120 color camera. It is cheap and good entry level camera. If you also wan't to image deep sky objects like nebulas or galaxies, you "need" a cooled version like the ASI 183 MC Hope this makes things easier for you :)

[@johnlaccohee-joslin4477]

Oh look, someone knocked it off the sink, do you want to use my super glue????

[@ExoPhotography1]

Haha, Maybe superglue is the shit for fixing mirrors :P

[@toml.8210]

I'm motoring this video to see if some wanker suggests you use Windex glass cleaner and a paper towel... ;)

[@ExoPhotography1]

Let´s hope not anyone tries it anyway :P
