Putting my new fast coupler to the test - SH2-101 Tulip nebula


Recommended Posts

Last night I put my new pillar with the special designed quick coupler (made by Herman ten Haaf) to the test. I did a pole alignment last week using Sharpcap and took everything off and repositioned the mount 2 times this week. Both times I had a polar alignment within 1' (1 arcminute) without doing an alignment (checked with sharpcap). I'm very happy with this. 

Last night this resulted in a guiding rms of less then 0,6" on both axes and so I could get very nice and small round stars. 

This image is a first result of only 6x900s Ha (5nm astrodon) because of incoming clouds using my TMB92ss and QSI583ws. But it is already promising and a nice target for the coming time to get more data.

Ha 3.5nm(baader) 900s


Oiii 3.5nm 900s  , with my old 7nm Oiii i would not have got anything like this.

Yours is cracking by the way. Guiding was a bit rocky but stayed on guidsatr for 4 hours.


I like your Ha a lot,
