Wonderful Observing with a Fullum Sandwich Mirror

I recieved a 21" 2005mm focal length sandwich mirror from Mr. Fullum earlier this year. I have only in the last month really been able to start to observe using the mirror in my ultralight-minimalist homemade dob.

The views the mirror have provided thus far are wonderful to say the least. Both deep sky and high power planetary images yield nothing to other high end mirrors I have used in the past. All this in a lighter weight, rigid, fast cooling mirror design.

Thanks Normand for the ideal 21" mirror

Daniel, I am glad you are happy with the views you get At F/3.75, it really shows the potential of a sandwich mirror on both deep sky and planetary, with a 20 minutes cooling time!!
Thanks for spreading the word

[COLOR="Purple"]That's great to hear Daniel!

I'm hoping to get an 18" f/4 from Norm later this year. I think these mirrors will ben the wave of the future for "amature' astronomy.
