Basic Knowledge: Attaching Your DSLR/SLR To A Telescope

[vtrmech1]

hi

can i connect to my telescope with only t ring because my telescope already have threading near diagonal..also if u remove the eyepiece can u tell me to find out the magnification i can get when i connect to dslr..

[truemartian]

@vtrmech1 If the threading fits I don't see why not. I have no way of knowing if it does. This is called prime focus imaging. In general, divide your telescope's focal length by 50 to get the prime focus magnification.

[vtrmech1]

@truemartian Thanks for the quick reply.I am a beginner so please dont mind the question logic.Can u please tell me how that number 50 came. Usually magnification is focal length of objective to eyepiece.right? Also if i buy a telescope with higher focal length

[truemartian]

@vtrmech1 To be honest its an area I am not exactly well versed in but in my research its a common number given as a "stand-in" focal length for prime focus. I suggest looking up keywords "prime focus magnification". This should bring up several articles on the subject that can give you a little more information on it that I. I hope this helps.

[vtrmech1]

@truemartian Thanks..I got a calculator for finding the effective magnification from web. Again thanks for giving me the concept of Prime focus magnification.

[truemartian]

@vtrmech1 Glad I could help!

[truemartian]

@vtrmech1 Keep in mind that standard magnification on a telescope is the telescopes focal length divided by the eyepiece focal length. Longer focal length scopes will give you a higher magnification with your eyepieces. The max useful magnification for small to medium sized scopes is usually around 300X. Typically high magnifications are best for bright planets and lunar observing. Lower magnifications are better on deep space objects.

I need to attach a Canon EOS 550D to a Saxon 767AZ can anybody tell me how much all the attachments will cost?

[truemartian]

@goldenguy12345 That question is probably best answered by contacting a dealer like optcorp com.

[goldenguy12345]

@truemartian Okay, thank you for the very fast reply!

Very useful. Thank you for taking the time to post this.

[truemartian]

@DebashisTalukdar You're welcome! Thanks for watching!

[MrConn96]

Great video. How much did all of that equipment cost? (Not including the telescope and camera of course)

[truemartian]

@MrConn96 A T-ring can range from $12-$60 USD. An adapter about the same. It all depends on what you need to fit your equipment so you will have to do some checking.

Great video T.M. could you possibly do a vid with some tips on exposure time and iso settings on camera ?Keep it up and Clear Skies.

[truemartian]

@daxmagavanaki This would be a topic a the edge of my knowledge base. As an intermediate myself the most I can say is try everything! :D

Thanks for yet another succinct and informative video! :D

I bought one of these cameras off Ebay specifically for astrophotography some years back, but it arrived F.U.B.A.R. like most second-hand items!

I'm going to save up so I can buy a decent, brand new one.

[truemartian]

@Gik1618 Sorry to hear of your misfortune. Thanks so much for watching!

[JCue23]

awesome man always love your videos please keep them coming!

[truemartian]

@JCue23 Thanks so much for the encouragement!

[archdelux]

[truemartian]

@archdelux Thanks man! You too!

You'll only see dead stars through your necroscope.

TrueMartian, thanks for the video, you seems to have knowledge about Astronomy stuff.

But why are your videos soo low quality ! You should have 1080p HD videos, with good lighting !!

Thanks

[truemartian]

@Ciwan2 Its an old web cam. I am working on saving to get a new camera. ;-)

[Ciwan2]

@truemartian Awesome ... looking forward to your future HD videos ... I can't wait :)
