- ZWO EAF
- dew shield
As expected and experienced many times previously, on time and competitively priced
Easy to use, set it and forget it. Keeps my target in focus while I get to nap.
Is terrific! I hated removing the dew shield from my Rasa 8 to place the Bahtinov mask, focus and then replace the dew.shield. The auto focuser perfectly focuses the Rasa and in a few minutes, i am ready to go! works flawlessly with Asiair!
The ZWO EAF was able to achieve the tightest stars and maintain the best focus on my C-9.25 SCT w/ f/6.3 focal reducer/field flattener, L-eNhance filter and OSC astro camera under a Bortle Class 8 moonlit sky! It was easy to install with the dedicated SCT bracket and use with my ASIAir Pro and iPad mini.
Focusing is the smoothest and the quietist. You have to look at it to see that it’s moving. I like it much better than the Celestron focuser which is very noisy. The EAF does protrude from the rear of the scope quite a bit, but is off to the side and presents no issues. The hand control is a must as far as I’m concerned although astronomy software found the EAF very easily through ASCOM.
