Hi Eduardo,
90% probability these are caused by some bright stars just out of the field of view. There is, regrettably, nothing we can do against it. I will try to baffle up a little the scope, but the only "help" one could have would be by moving the field of view either away from those stars, or (better) to include them. In this case, I would move the FOV a little to the right...
Best regards
Lukas
