Does anyone have any input in regards to this OSC/Chip. I am looking to assemble a quick grab and go setup in a OSC format. Thanks so much. If you think there is a better alternative please feel free to suggest. I will be putting this on one of my 102 apo's at F7. Looking to keep the arcsec/pix in the 1.5 to 2 range.

QHY8L is a bit 'old school' (can you really get those new?).

Anyway I suggest ASI294 or ASI071 or their QHY counterpart (or is there for the latter).

The QHY counterpart is the QHY168c.

Well it is old school but in its day it was a premier OSC camera. You can buy them used for a song these days...they have such low noise you can skip darks and use bad pixel maps instead. The larger pixels work great with longer focal length scopes. You will probably have to deal with some column defects and the TEC is unregulated...here's a few pics I took with mine...

Of course, QHY168 and QHY247 in color CMOS will be a good choice.
The QHY168C and QHY247C are 14BIT cooled CMOS cameras. A significant advantage over the QHY8L is the high pixel density and readout noise of up to 3 electrons. So if your telescope has high sharpness, you want to get a high enough resolution. Images, while also having good detail, can be considered with both cameras.
However, QHY8L also has its advantages. The CCD chip has a native 16-bit A/D. The output is 16-bit, compared with 12-bit and 14-bit ADCs. 16-bit ADCs can achieve higher sampling resolutions.

Absolutely nothing wrong with those images. Thanks!

I like the specs on the 168 Nearly identical FOV as the 247 with my scope but a little more forgiving with 1.4 arcsec rather than closer to 1.
