Did some tweaks and now a new reading

[Cathal O'Donghaile]

Good afternoon everyone.

I did some tweaks to my horn antenna:

I''ve run a half metre cable between the LNA and cantenna. The LNA itself is now in a sealed container inside a static bag. The probe itself comes from the black aerial that comes with the Smartee v5 bundle. The whole setup is easier to manage this way. After applying this, another reading appeared:



So, the reading at 0.5 Doppler is still there which AI Claude still reckons is a Hydrogen cloud. The new one at 0.3 Doppler it reckons is the Perseus Arm. The Az of my antenna is 225 and the alt 65 from Waterford, Ireland. Would love to know what you all think?
Instead of as before, I ran

Can you post a photo of the cantenna you ate using on this horn and how ot connects to horn?
