Heart & Soul

I thought the single narrowband filter revived an old lens. So I tried out last night. This was taken by Sigma 150mm/F2.8m, which was a good lens in the film era. But unfortunately seems to be a bit out-of-date for the digital sensor.

I was curious how it performed with Ha filter under Borlte 8 sky.

IDAS Ha STD 52mm + Sigma 150mm @F3.5 + ASI2600MM, 40 x 5

Yes, I’m glad Sigma 150mm is in my active lineup now.

20 x 5′
