Hello! I am new to astrophotography and I need a little help getting started. For some reason, when I attach my ZWO ASI 385 to my telescope (I have an Askar 103 APO), I can't see the sky. If I get an object centered in my telescope, (such as the moon) it appears as a very small dot, or as though I'm looking through a tiny hole at the end of my telescope tube. I've tried focusing it, using extenders, adjusting my settings, etc, etc. I think it's the way I put it into the telescope, but I'm doing it exactly as directed. Does anyone else have this problem?

avez vous tester de jour pour faire une mise au point sur quelque chose comme une montagne, une colline, bâtiments, églises, etc.. Hello! Yes, we tried that. It's as though the camera just shows a small dot of light/whatever the telescope is pointed at. We could see the moon through it, but it was extremely small with a black area (inside of telescope tube?) that wasn't the night sky around it.

avez vous fait celà? Yes, but for some reason, it works better with out it. With it on, I believe the screen was black or it showed only the small dot of light.

je précise bien sans l'installer dans le télescope *** Sorry- When not attached to the telescope and without the telescope adapter, I can see clearly and full-screen. However, with the adapter on, I see a white screen and it changes to dark if I hover my hand over it. ***

êtes vous en mode vidéo et le gain sur 100 environ ? *** I have an Askar 103 apo. Also, we tried it with an extender and the 1'25 adapter on, (doesn't fit but we managed) and we got a clear image. Should I need an extender? I use ASI Studio and even with the gain on 100 I can see nothing no matter how much i focus. ***

le format de l'image dans Asi Studio est bien 1920x1080 ?
pour ce qui est de réglages contraste, gamma, saturation et autres, tout en bas vous avez "par défaut"
avez fait un essai en reculant la camera à la main du tube optique et voir si vous pouvez obtenir la mise au point?
avez vous une barlow pour augmenter la focale?

the amount of reduction in focal length it takes to turn the moon into a dot is impossible to have with your native focal length and your camera

maybe can you show us a diagram of your image train, or a picture of it? the way you used it when you say you saw the moon as a dot; I think that would clear up everything in a flash
the amount of reduction in focal length it takes to turn the moon into a dot is impossible to have with your native focal length and your camera
you say you "see", can you explain what you mean by that, what are you seeing through? *** Sorry for the confusion, I'm not sure if you can see the photo I just sent, but the moon was in the 'little hole' as a small, unfocused dot. ***

Can we see what is attached to the camera, if anything. I mean, just the camera not the barlow or the scope, just the camera and whatever else is screwed onto it?
