Spider Trouble!

[Tony Connor]

Second night out with the Celestron Nexstar 130 and Skyris 236c, iCap imaging software...

Why am I getting an image of the scopes spider instead of Venus? TIA. Tony

Most likely because you can’t reach focus with your camera’s, so you may need to have an extender in place in your focuser to achieve focus correctly. Test it out in the daytime focusing on something in the distance, and if you need an extender move the focuser to max out position, then carefully undo the camera so you can very carefully pull it back out of the focuser until you see you get focus OK on your camera/pc. Just be very carefull you have a hold of the camera always.  Extenders can come in 1.25” or 2” sizes, of varying lengths like attached link shows.
