Why there is no Skywatcher EQ4:

Unlucky Chinese Numbers
Four
Main article: Tetraphobia

Number 4 (四; accounting 肆; pinyin sì) is considered an unlucky number in Chinese, Korean, and Japanese cultures because it is nearly homophonous to the word "death" (死 pinyin sǐ). Due to that, many numbered product lines skip the "4": e.g. Nokia cell phones (there is no series beginning with a 4),[5] Palm[citation needed] PDAs, Canon PowerShot G's series (after G3 goes G5), etc. In East Asia, some buildings do not have a 4th floor.

Why there may be no EQ7:

Seven

Seven is considered spiritist or ghostly. The seventh month of the Chinese calendar is also called the "Ghost Month". See Ghost Festival for more detail. During July , the gates of hell are said to be open so ghosts and spirits are permitted to visit the living realm.

But there may be an EQ8:

Eight

The word for "eight" (八 Pinyin: bā) sounds similar to the word which means "prosper" or "wealth" (发 – short for "发财", Pinyin: fā). In regional dialects the words for "eight" and "fortune" are also similar, e.g. Cantonese "baat3" and "faat3".

There is also a visual resemblance between two digits, "88", and 囍, the "shuāng xĭ" ('double joy'), a popular decorative design composed of two stylized characters 喜 ("xĭ" meaning 'joy' or 'happiness').

The number 8 is viewed as such an auspicious number that even being assigned a number with several eights is considered very lucky.
