This is NGC 4517 along with its' partner (NGC 4517A?). This was the ST8300 on the C8. I am still using 1-1/4 inch filters, so overall with the C8 and all, this setup is not my optimum. I do like the 8300 chip since I can bin 2x2 for more reasonable image scale on 1600 mm and still have a reasonably nice size image. Image and details are at:
