I've imaged M101 before, but wanted to try it thru the 115mm Stellarview. This was one of the few images that I was able to acquire at the 2015 Texas Star Party. The weather was poor with only a couple of nights providing decent imaging opportunities. The region framed well in the 115 and also allowed the capture of NGC 5474, a dwarf spiral galaxy. It's visible toward the lower left of the image above. I had hoped to add Ha to the image, but the weather didn't cooperate. So I extracted a pseudo-Ha channel using the red channel. That helped bring out the myriad of (NGC) emission nebulae that dot the galaxy. Clicking the above image will bring up a higher resolution image with a wider field of view. The linked image is rotated 90° relative to the image above. |
