SKY-WATCHER help

[AstroGeorgeD]

Hi guys, I've never posted here before and am new so bare with me if I have or haven't posted in the right area. 

I've been following alot on this forum recently and find it really helpful so wanted to be part of it.

I'm looking for my first astrophotography telescope. I've currently got my dslr linked up to my celestron nexstar 6slt and it's been working fine but not really ideal. 

I jave been looking at a few and wondered if which one if any of these two I should choose

SKY-WATCHER EVOSTAR 72ED DS-PRO

Skywatcher Startravel 102 AZ-3

the 102 is f4.9 but is achromatic 

the 72ed is doublet and f5.8

I know a lower f ratio is better but will the extra aperture of the 102 be better? I have been told to stay away from achromatic though. I also noticed the one woth the mount is £50 cheaper which to me says something. Any help would be awsome.

thanks 

George

If you happen to own a Startravel 102mm you can have a go at using it for imaging, and you can get some results.  But if you want to do some serious deep-sky imaging you should buy something like an ED scope - the experts can advise which one.

You will also need an expensive heavy-duty GoTo mount and (I suggest) the book "Making Every Photon Count" by Steve Richards, available from FLO.

Hi and welcome to SGL.  I don’t do imaging (strictly visual) but many friends are heavily into imaging. Please be aware that to get good consistent results is a steep learning curve and can eat deeply into your bank account.

2 suggestions- get the excellent book already mentioned, and a post in the imaging section is more likely to be seen by more folks who can help.

All the best, Ed.
