ok needing a little advice.

I have a Bintel BT200 f/5 scope that's quite banged up.
I have moved house 3/4 times over the 5-year period I have owned it and it's needing to be replaced.

Now im looking at buying the BT200 f4. is there a big difference between the f/4 and f/5 scope in terms on astrophotography wise?

just can't get my head around it all at the moment.

Thanks in advanced.
