It had been running through my head for a while.
On the 625mm with a red laser I could only collimate with my barlow laser when it was getting dark.
The red laser used was not powerful enough. But since I have green lasers I printed an adapter to replace the red with a green.
This one now allows me to collimate even in direct sunlight. To shoot Venus for example.
We can see on the staff that the reflection of the mirror eyelet is not centered with the exit hole of the laser. So collim to redo but since there are engines it only takes a few seconds.
The equipment used from left to right: green laser with its contactor stuck in the laundry basket, the adapter, a short barlow 2 times meade and the Tublug on which is made the return. In the end we can also print it out.
Have a good day.
