The Dwarf3 telescope looks good easy to set up as a pensioner ILike it but not able to use it yet many thanks.
So far I am very impressed with the dwarf 3 I am getting the hang of setting it up the app is easy to follow

By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow). Together with the high transmittance in main emission lines of nebulae, namely O-III(496nm and 500nm), H-beta (486nm), N-II(654nm and 658nm), H-alpha(656nm) and S-II(672nm), the filter is suitable for enhancing the contrast and details for both visual and photograhic purpose at sub-rural area.
Suitable for CCD cameras and DSLRs. CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution and more natural color retention. Light pollution filters neither nullify light pollution nor make nebulae brighter. In most situations, they just enhance the contrast of a nebula and reduce the background brightness. The brightness of the nebulae is not increased.
WARNING:
Optolong filters are not designed for solar observation. DO NOT LOOK AT THE SUN WITH ANY OPTOLONG FILTER as permanent eye damage will be the result.
The Major Emission Lines of Nebulae: H-α 656.3nm, H-β486.1nm, OIII 495.9nm, OIII 500.7nm
The Major Emission Lines of Artificial Light Pollution: Hg 435.8nm, 546.1nm, 577nm, 578.1nm, Na 598nm, 589.6nm, 615.4nm, 616.1nm
