What you seem to be experiencing is what "we" call "defraction spikes". This is caused by "light scattering" of the spider vanes. This is what holds the secondary mirror. You may have noticed on photographs bright objects that have 3 or 4 spike like flares. This is a common occurance. This is especially common with very bright objects like the planets and stars. The thinner the spider vane, the better. No worries. |
