Wonderful!
Wednesday, 20 January 2021  | 

I have two of these now, one on my 102 refractor and now this one in readiness for the delivery of my Skywatcher Skymax 180 Pro Maksutov. They are really nicely made with silky smooth focus action. I agree with another comment on here that I thought the focus travel would be longer than it is but none the less will do the job beautifully and efficiently removing any primary movement issues that may or may not be present. Can highly recommend these and have give this product the full 5 stars.

Needed adjustment
Wednesday, 30 December 2020  | 

I got this for an old C8 to get round the image shift problem common with mirror focus mechanism of a SCT. Not as much travel as expected, maybe I did not read spec correctly. Anyway, I use original knob to get approximately in focus then fine focus with it, so that's OK. Not sure if the original bulky Celestron electric focus motor will still fit, I can live without it I think. Main issue is, it did not work out of the box, lost a star. Had I not already known about adjusting the pressure plate, or whatever it's called, it would be on it's way back to FLO with a bad review. A simple thing to do, a slight turn, if you have the right size Allen key, fixes it. Should have been tested and done if needed before shipping, in my opinion.

Fast delivery & Good quality!!!

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.

Great upgrade to a Skymax 150
Thursday, 16 April 2020  | 

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 .

Must-have upgrade
Thursday, 8 August 2019  | 

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.
