If you're not sure if a light pollution filter will benefit you or not (and it probably will), this SVBONY UHC Filter is a relatively inexpensive way to find out. Basically, it works by darkening the background so you can see more nebulosity that would otherwise be too faint. This filter allows one to really see small planetary nebulae that would otherwise be washed out by the background, such as the M42 Nebula, the Dumbbell Nebula, and the Lagoon Nebula. It helps with finding the little planetary nebulae because it dims everything but the nebula, i.e. you can look at the same spot with and without the filter, and with the filter in place the stars are dimmed somewhat but the nebula isn't. SV305C telescope camera adopts the latest IMX662 1/2.8” back-illuminated sensor. The camera has ultra-high sensitivity and ultra-low readout noise. It has better performance in planetary photography and lunar surface photography, and is very suitable for EAA. We have set planetary high-speed mode and deep space long exposure mode in the sharpcap software, users can choose according to their actual shooting needs, and realize one-key quick setting. Using HCG noise reduction technology, when the gain is increased, the HCG mode will be automatically turned on, which can greatly reduce the readout noise, and at the same time retain the high dynamic range of low gain. When the gain value of SV305C telescope camera is 190, HCG will be turned on automatically.
