How to Use Telescopes : Using Newtonian Telescopes

[GeorgeChar95]

newtonian dobsonian telescopes! That's what i call a true champion of it's kind!!!!

I have an 8 inch Skywatcher Skyliner and i will buy this X'Mas the SynScan system for it so i can take pictures and find objects like galaxies easy! Pretty much excited

Nice carpet! ;-) Good review. Thanks!

hehe, asthma. Azimuth!

[WatchmenDrManhattan]

nice house or office.

"You can move them in asthma"? No thanks, I'd rather move my inhaler to my mouth and avoid dying, but it's a nice thought.

Very helpful vid

[derman077]

Is it "this particular telescope" or "This telescope in particular" ?

[furian89]

how much r these any way?

[ingewie]

texts are too fast, good i got ears.. =(

remember to wait for the scope to cool down

[ParaglidingManiac]

@rastamaniakTHC,

Does the collimation change when it cooled down? Or does it stay the same "just be carefull do not rush" type of thing?

[rastamaniakTHC]

Collimation can change but this very very small so you will not even notive that ;] You can always first cool down the scope then collimate it ;]

[dirtyd365]

@rastamaniakTHC I keep reading everywhere to let it cool down. what is meant by that?

[HauntHouse]

@dirtyd365

The mirror surface needs to be very precise. When you go outside, the mirror will be warmer than the air so it starts cooling down. The inside of the mirror takes longer to cool and creates tension in the glass because it expands or contracts according to temperature. You won't have a good surface until the temperature of the glass is roughly even. Very expensive ceramic mirrors keep this deformation to a minimum. Tube currents are also a cooling problem.

@dirtyd365 Heat waves.... you see them coming off of your car on a hot day.... same thing with your mirror, but you notice them a lot more as you magnify more. They distort the image quite a bit, it's not terribly noticeable under 100x, though.

Is it xt8?

[WaukarusaKid]

Nice video.

However, I would recommend aligning the finder scope in daylight at a distant object; such as a chimney on someone's house

[VicAzcro]

Yeah, Thanks for this post! I'm looking to buy one for photography. I'm going to shoot for a low-end newtonian, I'm currently eye balling a 6". I might be buying 2 of them, My father is old, and isn't capable of alot of movement, But I think that he would lose about 60 years, looking at the stars and moon.

Basically turning him into a little kid, who couldn't wait for the sun to go down. LOL.

If I threw you some links, would you be able to tell me if these would be decent to buy?

Thanks!

@VicAzcro:

man thats a brilliant thing to do, hope you n your old fella have had some good sky time since this comment was left...

what did you buy btw? I'm hunting myself now...

best

That was really informative. Thank you. Could you make a video on how to align a Newtonian to the polar axis. I have a Newtonian mounted on a EQ3 and live in the Southern Hemisphere. Looking forward to your video on this.
