M51 Whirlpool

[Gerr]

The Whirlpool Galaxy located in the constellation Canes Venatici was the first galaxy to be classified as a spiral galaxy. Its distance is estimated to be 23 million light-years away from Earth. Now widely imaged and a must have in any budding astrophotographer's DSO album!

This is my latest version from my Bortle 6 class sky.

Lights: 89x60secs  (ISO800).  Canon 650D. SW200P. Optolong L-Pro filter.

HEQ5 Mount - guiding at 0.5 total RMS error (mediocre due to gusty conditions) taken 7th May under waning Crescent Moon.

CC's welcome.

Very nice image Gerr.

Ca I ask whether you are using a barlow lens in your  200P, or does the coma corrector give you sufficient inwards focus ?

Hi Noodles,

No barlow. I can achieve focus with or without the coma corrector too. Never had a problem focusing with the SW200P. Though I maybe lucky in that respect as I have noted on this forum.
