Image of Orion the Hunter constellation last night. Due to only a few hours before the snow clouds come rushing at 21:45 hours.
I quickly made a move set the IOptron Smart EQ mount and the Baader Modified and cooled Canon 600D. Made a wonderful wide field image. Something totally different and no telescope were used in the process.
I’m really quite chuffed with this one, but a word of warning this is no easy target especially up north, where the Orion constellation lies quite low in the sky, You are literally vulnerable to surrounding light from the street lights and houses. A slight hint of lens flare will be projected on to the image. I had to use a lens shade to minimise the sky glow, And would help if I had a clip in Light pollution or CLS filter. Got 2″ filters for telescope use but not for camera lenses. I would really preferred to use ISO 800 and 2 minutes to get a ton of detail.
But with ISO 400 and 1 minutes exposure it’s not bad image and a slight hint of the Banard’s loop is seen. I needed more exposure and time and a LPS filter would have helped a lot. But end of the day it’s balance take the rough to the smooth and has long you can judge the conditions of your sky and limits, you get good images. To say I used a stock budget 18-55mm Canon lens the image is very crisp. One key factor with any long exposure Astrophotography, the EQ mount is the most important part of any set-up. Always!!! Consider the mount first before any Gucci telescopes and fancy cameras or lenses.
