 Do you want to use the mount to do any deep sky imaging? Both links are to Alt-Az mounts which will not be suitable for astrophotography as they will introduce field rotation, unless you use a very short exposure. Alt-Az mounts are fine for visual observing.Peter 7 November 2024 at 5:51 pm #626318 Dr Paul LeylandParticipant Dr Paul LeylandParticipantHi Jack,

The Seestar uses 10s exposures to keep field rotation within its acceptable limits. 7 November 2024 at 8:23 pm #626319 Robin LeadbeaterParticipant Robin LeadbeaterParticipantOr fit a field rotator before the camera Or a wedge provided the software recognises this equatorial mode 7 November 2024 at 8:32 pm #626320 Robin LeadbeaterParticipant Robin LeadbeaterParticipantHere’s the Celestron version.
