Hi.
I have tried to image SH2 157 in the Cassiopeia Constellation. When found in ASIAIR Plus sky atlas, hit the GoTo button and I'm told that it is below the horizon.
I am in the UK and can clearly see Cassiopeia above me.
I made a search for the Bubble Nebula, also in Cassiopeia and very close to The Lobster Claw nebula. This was found, pressed the GoTo button and my mount slewed straight to it.
I've also done some searches for other nebula and found the following to have the same search result, target in below the horizon. These targets are: Sh 157. Sh 103. Sh 1340. Sh 105. Sh 125. Sh162.
As you will see they are all in a similar area of the sky.
I've uninstalled and reinstalled the app. I checked coordinates for targets and they seem correct.
I'm at a loss now.
Please help. Thanks.
Keith
