Just went out and looked at sun
Sorry, you are not Hubble telescope
the center flare (at the center of the spikes) should be a little bit bigger and softer looking.
If you want you can edit it by yourself, i can't use my pc, now i'm using the phone D:
what reference photo(s) did you use? Just curious.
Any photo of Hubble Gallery have that flare, i used this photo anyway...
