After airing my concerns with the modified D7100 to LifePixel, they graciously replaced it with a modified D5500. Naturally, it was cloudy for a week after it arrived but I finally got a chance to test it out on Saturday. I collected 88 minutes of data and got this image. Not terrible for a first attempt I think. The learning curve is extremely slow when you can only practice once a week for 6 hours. Hoping for clearer weather in June.

Great image.  Just so you know, the D5500 is ISO invariant so you can shoot it at 200 (experiment with this, most shoot at 200 though).  Going higher than that is just hurting your dynamic range.

This is a fine image. Six hours of practice a week, you are a lucky guy and you have good skills.

Congrats on a nice start, !

 

Off topic - but since your image gives me the opportunity...

Why does no one ever mention the head of the fiery eyed dragon, glaring at us (or it at the pelican) between the pelican and N. Am.

Any chance you could repost that graph? It's really hard to see/read

Some good info regarding ISO and how it works on a DSLR here too.  http://dslr-astropho...trophotography/

Oh dang! Thanks for the iso lesson. I had no idea about that. When shooting macro with flash I tend to shoot at iso 64. Good to know slower iso is the way to go for astro as well.

Not a general rule, it depends on the camera. But for the D5500 it’s true.
