FAQs:
What type of observing is the StarQuest-90MC best suited to?
This telescope is well-suited to lunar, planetary, and double-star observing, where its long focal length and high-contrast optics really help. Features such as craters on the Moon, cloud bands on Jupiter, and the rings of Saturn are clearly visible under steady skies. It is less focused on wide-field deep-sky viewing.
Is the mount suitable for beginners?
Yes. The mount can be used in a simple alt-azimuth mode, which makes pointing and observing straightforward for newcomers. As experience grows, switching to equatorial mode allows smoother tracking of objects as they move across the sky.
How stable is the mount and tripod combination?
The mount uses precision gearing and a clutch system on both axes, which helps movements feel controlled rather than loose. Combined with the aluminium tripod and accessory tray, it provides good stability for a telescope of this size and weight.
Can I take photos through this telescope?
Basic imaging is possible using the supplied smartphone adaptor, which fits most phones between 54 and 90mm wide. This works particularly well for capturing the Moon and bright planets, where short exposures and high contrast suit smartphone cameras.

The Buy Now Pay Later option comprises a 36 month loan following a six month deferral period.
During the six-month deferral period, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is partially repaid within six months, the remaining interest will be adjusted to reflect the new balance. If the loan is fully repaid within the six-month deferral period, then no interest is payable, however, a £29 early settlement fee is payable in respect of repayments within these six months.
Following the six-month deferral period, Novuna Personal Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 18.9% APR (representative) on outstanding balances (backdated to the first date of the loan). Novuna Personal Finance will send a reminder letter approximately one month before the six-month deferral period is due to elapse.
