St-80 moon shots march 26th

[BillPickle]

So i decided to go easy and try some tracked moon shots instead of dso tonight...

The first 2 pics are the st-80 with a x2 barlow.

Im really surprised with this despite the CA...

last pic was my 114mm reflector with x2 barlow to bring it to focus... im not seeing much benefit to the 114mm with the longer focal length really.

Perhaps a more experienced set of peepers can enlighten me though.

Im finding it difficult to obtain a better focus than this. Could it be the shutter at iso100 being too low? think they were all 1/35 of a sec at iso 100

Shutter has no effect on focus.

How are you firing the shutter? If you touch the camera, it will create vibrations in the rig that may take a few seconds to settle. A remote is best, or a cable.

Using a tripod? Hanging some heavy weight in a bag from the tripod will help with stability. This works for mount tripods as well.
