Hi David, Thanks for the reply - I took the leap and bought a set of CatsEye collimation tools and boy what a difference having a 2" Cheshire makes. The combination of the Blackcat XLS 2" cheshire and the Blackcat Xl for the primary make thing so much easier. Now the Catseye XKLP auto collimator - i'm not a fan of that - as i really struggled with it. The good news is that i sorted my collimation and it looks so much better now. Cheers, Rich.

Hi John, was that for visual or Imaging ? It's good news if there is very little impact on diffraction spikes as i only want one of these CNC cells to stiffen up the front of the scope as i think the oversized secondary of the Quattto Series flexes the standard spider vanes as it moves across the sky.

Hi All, Just wondering if anyone out there had upgraded their secondary spider to use one of these CNC secondary cells ? just looking for some feedback to see how much of a difference they make - primarily interested from a collimation perspective, but also interested to see how much it impacts your diffraction spikes. Cheers, Rich.

Coma on one side of image only
Northernlight replied to Northernlight's topic in Imaging - Discussion
So you think this is secondary rotation error ?? -
Hi All, I recently bought a SW Quattro and in the process of setting it up. So far i'm seeing some strange things during the setup process. I've used a 2" concentric tool to setup the secondary and in the tool the secondary appears perfectly central and presenting a perfect circle but the inner circles appears oval shaped as per Image A below. looking down a cheshire sight tube - The black shadow which appears oval is more obvious as per Image B. So not sure what is causing this - i.e.is it tilt in the focuser or maybe rotation or tilt error on the secondary. Any help woul

Hi All, I'm setting up a new ES HR coma corrector and initial testing shows coma only on the left side of the image. I know the spacing between my camera and coma corrector isn't quite perfect as i'm waiting for some fine tuning adapter - Is this likely to be some sort of tilt issue. ? Maybe on the focuser Cheers Rich,

The Future of Imaging - Is everything heading OSC
Northernlight replied to Northernlight's topic in Discussions - Cameras
you all make fair points - i just think that there is a much larger choice of OSC camera when compared to options available for mono in the consumer market these days, whilst going back 5-10 years ago the market for camera was predominantly mono, so i think there has definitely been a transition to more people wanting OSC than mono. -
Hi All, I just recieved my new 10" Skywatcher Quattro yesterday and noticed that the light baffles only come half way up the tube - Is this another chnage in design, as I thought on previous earlier models i thought that the baffled came 3/4 of the way up the tube, i.e. 75% of tube covered vs only 50% I might have it all wrong and that they always had 50% of the tube covere din baffled, so would love to hear from other quattro owners. Cheers, Rich.
