Additional fee for replacing the GSO 8x50 straight finder with the GSO 8x50 RA angular finder. An option recommended for people purchasing GSO Dobson Deluxe telescopes and GSO optical tubes. Exchange possible - after e-mail approval - also for tubes of other brands.

An angled finder is (usually) much more convenient than a straight finder, and it gives an image of the Earth, not inverted, both left/right and up/down.

Comments
• the option applies to new equipment (telescopes / optical tubes), we do not perform this type of replacements on used equipment
• in the case of purchasing a GSO telescope / tube - you can exchange it by purchasing the telescope / tube and paying an additional fee for the replacement, without the need to contact the store staff
• if you purchase a telescope/tube of a brand other than GSO (Taiwan), it is necessary to contact the store staff to obtain consent and confirm compatibility - please write an e-mail
