Description

Good morning my fellow Lensfriends!

Perfect nights for imaging are getting few and far between these days with all the crazy weather patterns all over it seems. Just a few days ago we had thunder, lighting, hail and very close to us funnel clouds and tornadoes right offshore. For this area and time of year these are crazy conditions!

The silver lining to all this was after the storms blew through it was absolutely stellar sky conditions up there. These kind of nights here make imaging with a modded DSLR really enjoyable. Sensor temps where right around 50f. Just where I like them. The colors captured here with my modded T5i using a custom WB I set with noon sun and a grey card are more like other imagers pictures I've admired over the years on the net but could never really come close to even using a more expensive and stock Canon full frame. Thanks much to Hutech in California for such wonderful work on my camera. I highly recommend their services.

Auto guiding in such clear conditions is also a joy and enabled me to get 10 minute exposures with nice rounds stars without a single bad exposure in the bunch out of 20. Love it when things come together and just work especially after a Windows update...whew!

This is with my Stellarvue SV80ED doublet @ 560mm using an AT2FF. 20-600 second lights @ ISO 800, 25 darks and 25 bias frames. No flats or dark flats needed at all (gotta love that). Everything was then stacked in DSS using Median and Mosaic method and given an initial edit in DSS before saving to a Tiff. Then onto PS for a slight stretching and finally LR for a small tweeking. Let me know your thoughts on the final outcome here.

Be well and look up!
