Any recommendations for a x1.5 quality Tele-extender or Barlow which would fit a 1.25" set-up.
I'm looking of such an animal to give me a full frame solar image (ASI 1600MM) on the ED80.
Beren,
Thanks.
A pretty expensive solution, not sure what the final magnification would be - it does say it's a tele-extender so the back focus (nosepiece-T2, T2 to T2 tilter, T2 to camera) shouldn't make any difference .....
In the meantime I found "in my box of tricks" an Astro Engineering, x1.6 Magni-Max (AC555) Barlow. (I tried this years ago to improve a guide camera set-up)
It's a 1.25" filter thread so needs a bit of ingenuity to get a fit to the T2 tilter.....
Let's see what can be done.
Update:
The filter sized AE Barlow...found a 28mm to male T thread adaptor, this then needed a female/ female T thread at one end to mount a 1.25" nosepiece.
Where do you get a female/ female T thread adaptor??
Baader and Agena do one....what other options?????
An inspired thought...the T2 camera adaptors I have (many!!) have the T thread insert - three small grub screws - what about it?
Yes! removing the insert provided an ideal female/ female...
Mounted on the front of the usual ZWO T2 tilter managed (between wind and cloud) to get a solar image. The image size is ideal!
Hmmm OK, but what about quality? resolution?
I'm taking a couple of images to check things out....stay tuned.
