On the 2nd of December the weather was great again, so I decided to try out M33 with my now pretty automated setup (so nice to sit inside watching a movie while the RP4 just controls all :))

The end result was pretty great IMHO. Your AF3 did an outstanding job of keeping the focus throughout the imaging session. It's a truly amazing piece of hardware you've developed for a very reasonable price. I can only give it my highest recommendations.

New autofocuser from on my new TS 60 APO. Perfect fit, all i need is a #clearsky.

I used AF1 ``in the field`` first time last weekend. It worked wery well. I tried focus with Bahtinov mask first, took a few photos and after that ran the APT autofocus procedure. The focusing was much more precise. The coma in the corners of pictures was completely lost. Thank you for a great accessories.

I use the Deep Sky Dad 3D printed Zwo EAF kit for my RedCat 51 v2, it's great. It was easy to install using the YouTube video on the DSD website.

It allows me to very easily autofocus. I have it set up to refocus any time I start a new target, and every 2 hours, and any time the temp changes by 5 degrees C.

Here are two photos taken using it on my RedCat 51:

This is a shot of the AF3 focuser for the William Optics Redcat 51 from Deep Sky Dad. This thing performed BEAUTIFULLY on my first night out. Big improvement over trying to manually focus that scope with the Bahtinov mask.

I was getting picture perfect V-curves from SGP and my first image with it came out well ( The installation was easy (20 mins) and the manufacturer provided the SGP setup on his website. Couldn't be happier!

I have no affiliation with this product or the company. I was just very happy with the product and I wanted to share my impressions with the Astrobin community.

An awesome piece of gear made by an astrophotographer for astrophotographers. Fully ASCOM ready and custom 3D printed mounting platform

Multiple autofocusing solutiuons by Deep Sky Dad! Highly recommended.
