Summer's heat and the nice FRA600 out testing the asi294mm in near infrared

Description

In June, above 52N there is no astronomical night, sun is always above -15 deg altitude. The ultra hot summer with temperatures going up to 35 deg C (almost 100 F) makes the sky clear, and the seeing bad. Yet, no real deep sky photo might be taken anyway. I have used this opportunity to test problems caused by the 294mc/mm sensors in near infra red (Ha, S_II). They are easily calibrated, phew. The pristine fields in east Poland are really a charm, and their sky is awesome... but not in June.

The effect of these tests can be seen here:

Happy summer and don't be mad -- I am posting setup pics really rarely
