Easy mounting - no need to dismount the focuser - reduction is adjustable.

A 1:10 micro focuser has been well proven in practical observing and astrophotography, it allows fine focusing. The 1:10 Micro Reduction Unit from Lacerta can be easily retrofitted to many Crayford focusers. The retrofit is done with the focuser mounted - disassembly is not necessary. The gear reduction does not fit on rack and pinion focusers.

The 1:10 reduction fits to ...
... all focusers with four base screws in 33 mm x 22 mm spacing
... Skywatcher ED refractors, Newtons, Dobsons, Black Line telescopes
... Vixen ED 80 and ED 100
... Orion USA ED refractors, Newtons, Dobsons
... and many others.

Fantastic Addition

The Lacerta upgrade kit is a fantastic addition to my Sky Watcher 300p Flextube. The shipping was fast and the package arrived undamaged. Installation is quick and very simple, all you need is a set of allen keys and about 5 minutes of time. I highly recommend David Astro and will definitely be purchasing from them again in the future.

Nice improvement

This dual focuser kit is giving my 8" dobsonian the focus improvement I was hoping for. It was very easy to install by following the video on Reflactor channel on YouTube. David Astro processed the order very quickly.

Excellent Service

Thank you for your help in my purchase of the Lacerta kit to upgrade my crayford focuser to a dual speed focuser. I initially e-mailed a question about being concerned if it would fit my focuser. Someone promptly replied that same day by e-mail not to worry it would fit. It arrived on the exact date promised and I installed it. It works beautifully. Thank you very much.

Butter smooth focusing after an easy install

Quality well-made product, easy install and tuning. Instructions on the Lacerta website (PDF)are clear and easy to follow. The 1:10 movement gives a smooth focus and no rollback with heavier 2 inch eyepieces. Great inexpensive upgrade for your crayford focuser.

Skywatcher 200MM Dob With Lacerta Focuser Upgrade

I purchased this Lacerta dual speed focuser for my 200MM Skywatcher Dob for fine tuning the images. I ordered my Lacerta focuser from David Astro , quick shipping and within 24 hours I had the focuser. The focuser feels very solid and ultra smooth, and it takes 20-30 minutes to install the focuser, and then fine tune it. and looks like factory installed focuser on my Skywatcher telescope. I have used heavy eyepieces like 13 Ethos -1.3lb , 35 Panoptic 1.5lb holds with ease and zero shift. I am recommending this focuser if you were wondering about it, get it. and when fine tuning the stars Wow brings it in superbly. Clear Skies
