Again great explanation, thanks for your help. Excited to try it out when it arrives! Really awful weather here in the UK though so might need to wait a few nights...

Wow thanks for the detailed and informative response, that's been really helpful! And that's such a great image of Jupiter. I've read / watched videos about image stacking (PIPP, Autostakkert, RegiStax, etc.) but obviously haven't had a chance to try it for myself yet... For capturing that photo (or video frames) were you using a Barlow lens (and if so was it 2x) or just the camera straight into the scope? Thanks again!

I've recently acquired a Sky-Watcher Explorer 130M (900mm focal length, 130mm aperture / mirror size, maximum recommended magnification 260x). I've also ordered a budget SV105 camera for getting more into astrophotography. As discussed in the thread here, the SV105 has a field of view equivalent to looking through a 4mm eyepiece. If I use a 4mm eyepiece that's a magnification of 225x. Adding a 2x Barlow lens the magnification would be pushed past the maximum limit to 450x. I know that you can't really talk about "magnification" in the same way regarding cameras, but does the same limit apply? i.e. if the FOV of the camera is equivalent to a 4mm eyepiece, will a 2x / 3x / 5x Barlow result in a blurry image because of the maximum recommended magnification? Or will it be crisp because the camera doesn't work the same way as an eyepiece?
