Hi, I've got a Skywatcher Heritage 130p reflector, and if i insert anything less than 10mm eyepiece, the image won't get crisp. I guess it's normal, but as I'm very new to astronomy, I'd like to know what the sharpness depends on exactly.
Is that the focal length (how fast the telescope is? ) or the size of the mirror and how much light it gathers? Or both affect it the same way?
Are things the same with refractors in this regard? Thanks.
Hi I went out this early evening to see if Saturn and Jupiter were observable but the clouds dominated this area.
The Moon however was in a very clear area so I used my MeadeETX90 with a bino viewer with two 25mm eyepieces and spent some time viewing it.
The views were really good as the Moon was in the first quarter which is when I feel is one of the best times to view it as it is not to bright.
The shadows that were being cast were amazing but once again the clouds rolled in so until the next time??

I'm getting desperate over this hobby (but I refuse to give up); with every change new problems set in. I purchased a SVBONY SV106 (60mm - 240mm) guide scope to replace a 80mm - 400mm scope, I was using as a guide scope which was installed on the Orion 8 tube rings. I replaced the finder scope with the guide scope.
First issue balancing but that one I sorted out. Then I tried to focus the ASI120MM with the new guide scope. For the old one (80x400) , I needed 2 extensions (in fact the extensions are low cost barlows from which I removed the plastic lens) to get focus. To align the new guide scope, I used a 17mm eyepiece and that went ok while pointing at some far away trees. But I could not get the ASI120MM focused on the same trees, not with PHD2 nor with Firecapture; I turned the gain way down, but with or without extensions, no focus. As bad weather is (again) setting in and the scope is permanently outside I had to stop trying.
So I take on this break to get some assistance. Anybody any advice on this, for
