If you plan to reuse the alignment later (for example if you are in an observatory)

The HCG (high conversion gain) mode reduces the read noise at high gain levels without any loss of dynamic range

ZWO UV/IR-CUT FILTER 2" Nadirus 16" thus allowing continuous high performanceThe UV IR cut filter is an indispensable accessory to block unwanted infrared and ultraviolet light where the ZWO is still sensitive. Note: Some ZWO UV IR cut filters may be labelled as only IR cut, but they are exactly the same and will also block UV. This filter increases the contrast, particularly in refractors, as the chromatic aberration continues in the infrared and ultraviolet spectrum. That is true also for apochromatic refractors where the
