Why not save up for something like an Astro Tech Ritchey-Chrétien astrograph and do the spikes properly. ;)

 :o

If i knew what it was and were i would put it i might!!!

I prefer the cheap artistic way of sticky pieces of string at a perfect 90 degree angle to each other on the end of my tube. ;)

Don't forget i'm still getting to grips with what a black,flat and bias does and where to put them.....in context to the other images. :o

Thinking about this is a black,flat and bias cheating :o :o :o ooooopssss don't want to start anything up....... :lol: :lol: :lol: :lol: :lol: :lol:

Ahhh..... but Rick spikes don't look good on ALL images & you have no choice as to whether you want them or not with a scope like that so then all us astrophotographers that strive for pretty images to hang on the wall would have to look for some Spike Removal Software or spend hours in Photoshop painstakenly cloning or erasing them...

At least in that enterprise you'd be in step with the professionals...

So what do you put behind the removed star spikes then?

Hopefully, you reveal things that're behind them, the light from which was mixed up with them (and spread elsewhere in their own spikes), but it gets messy. Not a huge lot different (but rather less extreme) than the early Hubble images (which needed pretty horrible levels of deconvolution etc. to get them presentable).

This isn't going to go away is it  :-?

Perlease can we just accept that some like diffraction spikes and some don't ?

All that's going to be achieved here is that some people will get ratty and end up at each others throats  :(

If you disagree with the subject, ignore it.  Arguing the point just prolongs it  :roll:

Locking the thread is not going to make it go away, let it run it's course, it will die eventually (please, please, please)

Admin can merge the "Spike Threads" so they can be ignored at will.

On the science point, if Hubble, Keck, Subaru, Gemini, CFH etc. stick fake spikes on their images, that is a bit of a different ball game from Joe Bloggs sticking them on an image he took from his back garden in Bromley.

Very, very funny Mr. G - So I need to know did you find that photo on the web or did you expertly apply those diffraction spikes yourself in Pshop.. if so is there beer underneath them....  :lol:

It's not fake beer is it  :o 

Don't toy with my emotions Tony :cry: :cry: :cry: :cry:

Fake Beer, I thought they stopped making Kaliber.  :D
I bet that sent a shudder down your spine the day that was introduced to the local Off License.  :-?
