1. I am planning to buy H-Alpha Filter what one should I buy and is 1.25" better or 2" with wide view eyepiece is better.
   thanks
2. Just got a celestron explorascope 114AZ telescope with a 3x barlow. I dont know if its a good telescope. Had nothing but cloud cover every night since i got it.
3. great video mate really did help :-)
4. I got a 2.25x Baader planetary QTurret Barlow, it is made of metal, it was about 50€, it has a detatchable lens that gives 1.3x , and quite happy with it. Combined with a 750mm focal lenght reflector and a 10mm ocular it gives nice sharp images and a good amount of magnification.
5. where can I get that Web cam?
6. does the barlow also increase the maximum possible magnification of my telescope?
7. When i bought my telescope it came with a barlow lense and a erector lense.
   Can someone please tell me what is a erector lense.
   Thank you
8. Where the heck is this place this place is my hevan Holly sh** dude ok i need to calm down
9. Hi Robert, I bought an Orion 2x barlow multcoated lens for my Orion 70mm goscope 2 but couldn't get focus for far distances (short distances are fine). Is my Barlow faulty or am I missing something?
10. Learnt a lot thanks for that.
11. Spend a few extra bucks and get that Apochromatic Barlow lens,because if you use a Reflector/Apochromatic Telescope that will introduce Chromatic aberration,the very thing these things were made to avoid.
12. My hasselblad is better
13. Can i have your e-mail pls i am interested some of your item. thanks.
14. Hello guys are new to the telescopes, my daughter received a 76 mm Firstscope and I would like to Barlow lens 3x or 5x buy using eye SR4mm and H20mm you think would be most appropriate?
15. Who in there right mind would use a five mega pixel web cam or a CC TV cam??? What are you saying...
    
    I want quality video and photography of the planets... I'm using a 35 mm SLR Canon 5D Mark 3 with the capacity of 22 mega pixel capacity as well as video... What do I need to buy for this set up... 
    
    I want Jupiter right in my living room if not bigger... I don't want to see some tiny dot...
    You guy's just don't get it... Go big or go home...
16. I currently have the celestron 130 slt , what would be the best eyepeice/barlow lense combination? (the 130 slt is 2 inch compatible )
17. Great video!!
    Just one question: what happens if you use a 5x barlow with a DSLR? Cannot that be used to get more detail of the moon, for example?
18. I've just purchased a second hand telescope as a starter to have a look at the night sky. These videos are by far the easiest to understand for me as a beginner and especially the one concerning the German equitorial mount set-up. Enjoyable learning. Thankyou.
19. I have a few old M42 Pentax camera teleconverters. Can they be used as a Barlow with the aid of a T mount adapter setup? TY for the videos, they are very helpful. 👍
