Yes that’s what I thought I have a 7mm to 24mm zoom eyepiece and with the ezxyz phone mount with my iPhone got some great shots with the set up. I think if the zwo mini scope dosent work will bite the bullet and get the off axis setup and be done with it. I will let you know how I get on. 
this is as a picture if the moon with my iPhone and mount 

 

That's a really nice picture. Was this with the zoom eyepiece and if so, at what level of zoom was it?

I too will have a bash at guiding my 127 Mak with the ASI120mm and the 50mm spotter. I suspect it will be ok using my DSLR as the imaging camera but less successful with the ASI178 due to it's smaller sensor.

 

Why do you feel the smaller sensor would require better guiding? My guess (which may be wrong) is that you're thinking the smaller sensor makes you more 'zoomed in,' so giving a more detailed image. It absolutely does not. What matters is the difference in pixel size. In a given scope the system's resolution is controlled by the pixel size. Smaller pixels give higher resolution and so need better seeing and better guiding. If I'm missing your point, here, I apologize.

All agreed olly, my terminology is at fault here. I think my understanding is about right.

I was trying to describe my findings from the guiding tool I posted up the thread. I should have said better resolution of the 

That's why I posted the link to that tool; a picture paints a thousand words...

The FOV of the camera and scope at prime focus should be small enough so you don't need an eyepiece or barlow. Also, I don't even know if you can reach focus through an eyepiece with a ZWO camera?

Short answer: Yes:)

Perfect thank you for the advice

Hi yes it was I think that was around 17mm zoom. It’s difficult to tell as there are no fine markings on the zoom piece to determine the exact mark but roughly 17mm
