Observing with friends, kids, visitors - the Wow factor of the ZOOM
I have been telling friends about my new hobby and people have been interested to come and share an evening of observation with me. I set up 2 telescopes and two binoculars and give them the tour. Recently I have been using the Orion Nebulae as my demonstration target as you can just barley see it by naked eye where I live. Sort of a lighter spot below and to the right of Orion's belt. So they can look and see and find it when they go home.
I show them the Nebulae in 10X50 binoculars as a first look. "Look for the stars that seem to have a fuzzy cloud around them." I use a green laser to help them find it.
Then I take them to the 80 mm scope with the 8-24 zoom. They look they smile, they may even comment on how cool this is.
OK, now twist the barrel and go up in magnification. WOW! There is always a wow with the zoom, especially with kids.
Then I take them to the 8" Dob so they can see that view.
The zoom works so much better than taking the scope back to swap from this fixed FL eyepiece to that fixed FL eyepiece. Swapping eyepieces does not have the same impact and you don't get that clear and obvious change in magnification. But the zoom gets a wow every time.
If I put it on the moon I may also drop in a 2X barlow and then zoom, WOW!
I like the zoom personally.
In the ETX 80, 400 mm FL, I grab that 8-24 mm zoom and a 2X barlow and I can view all night. In my ETX 80 this gives me 16X to 50X with no switch of the eyepiece. Drop in the barlow and I have 32 to 100. For most things that is all I need.
In my 8" Dob, 1200 mm FL, this gives me 50 to 150X. Add the 2X barlow and I now have 100 to 300X.
If I want to get a better view on something I can drop in a fixed FL eyepiece but most of the time this is fine. And it gets that WOW when I am showing astronomy to other people.
Offered for your consideration.
