Thanks for the review. Very well done and in great depth… even the flies cooperated! I don’t know how you convinced them!! :-) I think your takahasi was slightly brighter on the image, how did it do at night??
Takahashi is the best, and is great for lunar and planetary. I have not used it on the deep sky targets, because of its narrower field of view, but I will try it.
I tested the zoom eyepiece on some close double stars at high power using an 80 mm APO f/6 triplet and ED f/7 doublet. It held up well against my TV Radians. My only gripe is that not all lenses are fully multicoated (as advertised), but neither are most of the eyepieces in the reviewer's collection.
Thanks for showing the action of the EP from the bottom! Now I understand why the barrel is so long on this zoom. Definitely can't use this with my new binocular telescope
@@TheAstronomer EPs need to have a short barrel or they won't seat fully in my BT-80A and then focus cannot be achieved. Testing EPs with it, my 24mm Panoptic works great, my Baader Zoom won't work at all.
OK, I see. How long should it be to sit in the eyepiece holder? I measured these with a vernier: my two Televue Panoptics have a 21mm metal end, in SVBony Aspheric 23mm,10mm and 4mm eyepieces it is 21.5mm, in my Zeiss Pl-10x microscope eyepieces (equal to Panoptic 24mm) it is 29.5mm and in the SVBony 3-8mm zoom it is 36mm. So I think your best alternative can be SVBony Aspheric. Lots of cheaper eyepieces also can fit, including the kit eyepieces of Skywatcher Super 25mm and 10mm.
@@TheAstronomer I've got 1x the 10mm & 23mm Aspherics that I hope to try the next time the skies clear. The zoom is great for f/6 and below, so I still plan to buy it for this little FS-60C I picked up recently. 3-8mm is 118-44x. Might be all that scope needs for grab-n-go!
If you already have it , yes , if you are going to buy one, then get a Nirvana 4mm and 7mm. They give you a comfortable 82° field of view. 3.2 mm will give too much magnification and you will start to see your own eye's floaters (unless you don't have any floaters).
I’ve just bought the starguider 7-21mm zoom eyepiece just wondered if you have tried it.i originally bought the svbony sv191 zoom before and it was extremely stiff and hard to use!I have the starguider eyepieces and find them to be excellent so thought why not buy the zoom also!
Love your videos and the fact you do these reviews but wish you would strap a go pro to your head and use both hands instead of fumbling about with one 😁👍

Excellent review, thank you so much. It really helps in the decision making.
Thanks! Great review of this eyepiece, finally!
You are very welcome! And Thank you for watching!
Great review. Do you think this would work well with a 6se f/1000?

My only gripe is that not all lenses are fully multicoated (as advertised), but neither are most of the eyepieces in the reviewer's collection.
The BST Starguider ED 8mm and Takahashi EMC LE 7.5mm are both not only multicoated, but also well baffled and lens edges blackened.
What would happen if use 2x barlow ?

Glad to be of help l! Does it mean it will hit something in the binoviewer or Barlow ?

Good luck with your trying of eyepieces for your binoviewer. I hope you will find the right eyepieces at a reasonable cost.
My wife wants words, I've just bought myself one. 😅
Great review, looking forward to trying it out. 👍
I am also looking forwards to try it on planets Saturn and Jupiter with it!🔭🌌
@@TheAstronomer hope we get a video? 👍
Yes, I will try to make a video of the night time use of this eyepiece.
I have uploaded the night time video testing the zoom eyepiece on planet Jupiter.
The tmb 2.5mm would be too much for my 8 inch dob but would the starguider 3.2(375x) be ok?wanted something powerful for the moon!

I have several zooms in that rsnge . They are alright if you want to save money . I tendcto use noe only the SVBony 3-8mm Zoom Eyepiece .
Exchange rate fluxuations make a big difference as well
May be! Our economy at the moment is going down in the UK.
Love your videos and the fact you do these reviews but wish you would strap a go pro to your head and use both hands instead of fumbling about with one 😁👍
May be one day!
The 3-,8 is the best
Yes, that eyepiece is a gem. I can not believe that SVBony has made such an excellent eyepiece for planetary observers.
