M35 - Single Frame D5300

[Jerry_Lodriguss (Jerry Lodriguss)]

Here are two beautiful open clusters in Gemini - M35 and NGC 2158.

It's interesting to note the golden star colors in NGC 2158 compared to the bluer star colors in M35. This is because NGC 2158 is a much older cluster.

I though I would see what I could get out of a single exposure with my new Nikon D5300 DSLR camera.

This is one 10-minute exposure at ISO 200 at f/6.3 with my AP 130EDFGT refractor at 825mm of focal length.

The big thing about the D5300 is it's low readout noise at low ISO. This gives the camera a large dynamic range and the ability to better hold star colors in the highlights at long exposures because a low ISO can be used.

It's a nice pic Jerry !!
Interesting test with your new dslr...
Two clusters with different ages and different colors close to each other on a single shot... like it

A great composition Jerry. Good demonstration of the DSLR capabilities.

Wow Jerry,
that's a great shot & 10 minutes is a long time with a DSLR.
I could only get 2 minutes even in Winter with my Canon EOS 1000d
& it would be all red in the bottom right hand corner.

cheers

Then Gemini is not visible as it is close to the winter solstice point of the Sun.

I was referring to all pictures not this picture.
It is a problem with the Canon EOS 1000d -
they go red in the bottom right hand corner
with long exposures.

Thanks guys for your kind words and for taking a look!

You couldn't get away with a single 10 minute exposure on any faint fuzzies, but for bright star clusters you can.

Very pretty star clusters, and your camera clearly is a great performer (so is the telescope!)

Beautiful cluster Jerry!
