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

The Optolong CLS-CCD broadband filter is designed for CCD cameras and astro modified dSLR cameras to improve the visibility of various deepsky objects. 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 highly transparent in main nebula emission lines at OIII(496nm and 500nm), H-beta (486nm), NII(654nm and 658nm), H-alpha(656nm) as well as SII(672nm), the filter is suitable for enhancing the contrast and details for photographic purpose at light pollution area.
This CLS-CCD filter is different from the CLS in a way that it cuts off light at the infrared part of the spectrum between 700-1100nm. Recommended for color CCD cameras and astro modified DSLR cameras for astrophotography. Work well on most emission nebulae, planetary nebulae and supernova remnants. Noticeable boost in contrast and visibility of the fainter outer detail. Please note that light pollution filters do not completely eliminate the effects of light pollution and definitely do not increase the object’s brightness, hewever they increase the contrast between nebula and night sky by making the background darker.
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.
