I bought it to apply to SkyMax 180 Pro. Received by Royal Mail. The delivery was fast and the quality was excellent.
I'm more satisfied with my purchase from FLO than from Alli Express.

Firstlight Optics service as usual fantastic. From order to first light 28 hrs. Thanks Guys.
This was an upgrade to my Skymax 150 and well worth the investment.
Fine focus easy to achieve compared to the standard system. It makes mounting and manipulating my Canon DSLR a lot easier. No interference with the standard focus knob and they compliment each other.
Initially I was worried about balance with this chunky focuser ,Canon 1000d , Baader 31 mm Aspheric and 2 " 2x extender but it just and only just worked out.
Overall very happy and I feel it added to my rig in functionality and ease of use.
Big Smile. Wonder why Skywatcher don't offer it as a package deal .

Bought this for our brand new SkyMax150 Mak. It just fits without blocking (or being blocked by) the standard mirror focuser. Crystal clear spot-on focus - a must-have if you want to do photography with this type of scope.

Great , best choice for my cpc 800HD , perfect to get the very best focus over planets , exelent qualaty , very solid and strong qualaty product
