Try aiming the scope at a bright star closer to zenith & look for the same aberrations. Better still would be Jupiter but only with it high in the sky (which right now means around 1am). This will ensure as much as possible less stray light getting in - & try to set up somewhere without strong lights impinging on your scope.
If these strong spikes keep on appearing it will mean looking at things more carefully. I have not seen any such spikes in my 127 Mak. Could also be the eyepiece. Is it very modest in cost? This isn't a certainty as a source, just part of the investigation.
Oh yes, Mars is flaming tiny right now. Earth is leaving it very far behind now in our orbit around the Sun. It won't be a good target for another 18 months or so. Jupiter and Saturn are coming up to opposition next month. Uranus and Neptune later on again, and they present their own challenges to identify.
And don't forget DSOs and the Moon!
