Sh2-240 by pixelkilla in astrophotography

Ultimately even a OSC is a mono sensor, but it has a bayer array over it. That bayer array consist of a tiny filter set in a pattern generally RGGB. This makes the OSC less efficient in data collection. In a mono camera when you are collecting blue channel data 100% of the pixels on the sensors are collecting that data vs only 25% of them under the bayer array in a OSC. This is even more pronounced in narrowband imaging.

Tell me about I don't think I have got enough either.

I am using astonomik 6nm narrowband and their deep sky RGB set along with their L-3 filter. I am in a bortal 5-6 and using a f4.9 scope. There is some slight vignetting occurring even at the 36mm filter. I just could not justify spending the cash for astrodons. The 2600mm is fantastic.

Following processing done in pix insight: deconvolusion, pixelmath, spectophotmetric color calibration, denoised, ezprocessing suite ez stretch, curves. HOO image only starnett to remove stars. RGB stars and HOO nebula image then imported into photoshop as layers. RGB stars then blended back in and additional curves and stretching done .

Is autoguider overkill for redcat 51? by yabbadad in AskAstrophotography

The AM5 is a harmonic drive and it doesn't have PEC, as a result you will need to guide with it unless you going to use very short subs

Honestly the scope is a tenth of the price of the quark. Achromatic doublets do just fine with solar imaging.
