These 8 inch DOBSONIAN MODS will BOOST your VIEWS

[@DobsonianPower]

I have 2 videos about the 8" Dobsonian mods. Here is the other you should watch: kzbin.info/www/bejne/bJTZm6R4frdqmdU

[@GarnettLeary]

Great upgrades. I especially like how you only flocked the secondary. A lot of people think you need to do the whole tube. That’s the biggest impact point,

[@DobsonianPower]

Hi Garnett. Yes, although an 100% protostar flocking always benefit a newtonian, i would not flock the whole tube in a modern newtonian. This simple and inexpensive mod does the job and we can really notice that while observing. But first it's important to check any light leaks on the focuser with a torch. Many people would be surprised how much light intrusion happen in some focusers. Fortunately i've checked my new 8" and it's fine, no leaks, but in my 12" i had to fix it. Now it's fine.

Wow, some really useful tips. I've got an 8" F5 GSO (it''s quite similar to yours, I think must be same brand) and I think it could use some modifications like the ones you mention here. Thanks for sharing your knowledge. Clear skies!

[@DobsonianPower]

[@vicamaral]

How about removal primary and secondary mirrors and painting the edges matte black and flocking the hole tube, you could also put in and dew cover to gave better views and keep stray light from the focuser and secondary mirror also check for stray light leaking at the focuser base, also don't forget the focuser tube you can paint that 2 matte black, clear skies mate.

Amazing video Tiago!! Very useful Tips!! I will try Some Of These 6 inch Newtonian! Thanks For Sharing!👍🏻

[@DobsonianPower]

Thanks Avanteesh

[@oz6123]

Great video! Could you share the dimensions of the dovetail plate you used to attach the Telrad to the mount? I have been thinking of a triple mount for a while and seeing your video I will commit to it. Did you have to drill another hole in the standard Telrad mount to fit the 2nd screw or is 1 screw enough to hold it tight?

[@DobsonianPower]

No drill. Links: 21cm Dovetail i use with the Telrad: amzn.to/3fCn8BK Tri-bracket mount: amzn.to/34RZrDr

Acho incrível que consiga ver objectos do céu profundo com poluição luminosa categoria 5! Basicamente é como se estivesse na cidade. Eu também consigo ver os mais brilhantes (nebulosa do Orionte, por exemplo) com binóculos, mas o brilho do céu estraga completamente a experiência. A propósito, estive a ver um mapa da poluição luminosa. A zona mais escura de Portugal é a Sul de Serpa e a norte de Mértola (entre essas duas localidades). Deve ser interessante visitar esse local de madrugada. 😁👍

[@barnoldtv1265]

Thank you, Tiago. I like the way you simplify everything for the beginner. You are a good resource for someone starting from scratch. One thing I would like to request, could you do another collimation video? Your current one is very informative, but it is very long, and takes a long time to get to the actual collimation. You have gotten so good at the "short and sweet" videos that I think you'd be great at a quick-and-easy collimation video for total beginners. Thanks!

[@DobsonianPower]

I may do that in the future but all my collimation only make sense to people that use the Concenter. My way to collimate is based on that simple tool, which i love. People that use all other tools have a bunch of other problems that i will not consider. That's why i didn't make that video yet.

[@Destide]

I'd say upgrade the fan too Noctua will run quiet, push more air and not vibrate as much

[@nordmende73]

Thank you very much!

[@DobsonianPower]

👍👍

[@grahamalgeo3867]

Is it a good idea to upgrade the spring for the secondary mirror in a similar way as the upgrading the of springs for the primary mirror? Your tips have worked great with my 8" newtonian, thank you ever so much.

[@DobsonianPower]

I don't think so because the pressure the central knob does against it along with the 3 knobs is strong enough. I never had a secondary mirror shifting ftom it's position. The trick is to have them very well tightened.

[@hooper365]

Looking through a black hole 🕳️! That's how I felt when I used my grandma's binoculars when I would put them really against my face the edges would feel like that of a black hole

Hello, Very much enjoyed your video! Can you tell me what Dovetail Plate you used under the Telrad? Thank You!

[@DobsonianPower]

Hi. My 21cm Dovetail is this one on Amazon but check also on chinese websites to compare prices and buy the cheapest one, they are all aluminum. Make sure they are equal to this one on Amazon though: www.amazon.com/gp/product/B092QN48B5/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=keepitsimp06b-20&creative=9325&linkCode=as2&creativeASIN=B092QN48B5&linkId=6fdf6b2628f82058c8c492930b6226f1

Where did you get the tube end cap from? (different to the fabric one you had in previous video) Or does it come with the telescope? Another nice video - thank you

I didn't see the link for the magnetic power bank, can you give me the link please? Thank you!

[@KevinSanchez-ts4pr]

The power bank from the link is not the power bank you used in this video. Did you use duct tape to hold the magnets in place on the power bank?

[@DobsonianPower]

Sometimes Amazon sellers update the links. That one is better than mine, doubles the power and has the same USB 5V DC 5V 9V 12V. The brand is the same although you may find another that works, this one it seems is out of stock now. Yes, i used duct tape to stick the magnets to the UPS.

@@DobsonianPower thank you so much!!!

[@johnbarry5036]

ive read of ppl who install a smaller secondary, for improved contrast/more light. Any comments on this?

[@DobsonianPower]

Yes i have. Only worth it if your secondary is too large. Usually is not. For ex.if i reduce my 8inch secondary i would have less light because it would cut too much the cone of light, it wouldn't catch all the light that come from the primary. Imagine a really tiny secondary, it makes less obstruction but also catch almost nothing. It should be the adequate measure, which almost it is in a new dobsonian. You check yours when collimating. If this still not very clear, ask me on live stream and i show you.

[@bahraintelescope1369]

I know nothing about this hobby. However I’m considering purchasing an Explore Scientific First Light 8” Dobsonian telescope. This a good choice for a first set up? Anyone have better suggestions or advice for a complete noob?

[@DobsonianPower]

3 words: GO FOR IT

[@SimRacingVeteran]

@@DobsonianPower - yeah my research has been pointing me to this. Seems a bit more finicky than a refractor telescope but the bigger aperture seems to be the way to go. Also needs to be collimated bit seems to be a great unit to start. Thanks for the reply 🤙

[@SimRacingVeteran]

@@DobsonianPower - does brand really make a difference? I’m still looking at an 8” Dobsonian but the one site I found in my area doesn’t have the Explore Scientific one in stock. However they have a Starfield 8” f/6 Dobsonian in stock. It has a fan on it. Is this Starfield unit worth 850 Canadian dollars? Or is there a brand that I should be looking at more than an other?

[@DobsonianPower]

@@SimRacingVeteran Don't worry about the brand because the manufacturer use to be the same. That Starfield it seems it's equal to mine which is also equal to many other brands. They only change the sticker.

@@DobsonianPower - it seems to be the case the more I research the Dobsonians that they’re all mostly the same. I suppose the better quality eye pieces are going to make the difference. Thanks for your help. I really appreciate it.
