Earl Posted September 9, 2013 Share Posted September 9, 2013 I have seen loads of 314L images, but i always seem to feel that the starts have a tendency to look a little bloated.Any thoughts on this? Link to comment Share on other sites More sharing options...
Freddie Posted September 9, 2013 Share Posted September 9, 2013 Got any examples you can add or post a link to? Link to comment Share on other sites More sharing options...
johnrt Posted September 9, 2013 Share Posted September 9, 2013 This will be nothing to do with the camera, and everything to do with optics / filters used.Stick a 3nm Ha filter infront of one and you get tiddly stars!! Link to comment Share on other sites More sharing options...
Earl Posted September 10, 2013 Author Share Posted September 10, 2013 Ah a very nice example where they are under control.Id rather not link out images that others have taken, as that would not be fair. Link to comment Share on other sites More sharing options...
ollypenrice Posted September 10, 2013 Share Posted September 10, 2013 Let's look at it the other way round, by showing good 314L images!http://www.middlehil...-O3B-master.jpghttp://www.middlehil...-border-850.jpgIt's a great camera but because it is also a relatively inexpensive one (I stress relatively!) it tends to attract beginners who may not yet be highly skilled and it will tend to find itself working in budget instruments, often refractors, which cannot compete with high end apos on controlling star size. In the link you see an expert imager using high end optics with stunning results.Olly Link to comment Share on other sites More sharing options...
Sp@ce_d Posted September 10, 2013 Share Posted September 10, 2013 I have seen loads of 314L images, but i always seem to feel that the starts have a tendency to look a little bloated.Any thoughts on this?Well, I have 3 of them at the moment & they are joyous to use. To follow on from Olly, surely matching well corrected optics to resolution / arc secs per pixel is the key here. As I'm finding out trying to choose scopes for my triple shooter project. There's a lot more to it than just bolting a CCD to a scope or three!Sent from my iPhone using Tapatalk - now Free Link to comment Share on other sites More sharing options...
JamesF Posted September 10, 2013 Share Posted September 10, 2013 Ah a very nice example where they are under control.Id rather not link out images that others have taken, as that would not be fair.You could always ask the poster first if they mind if you use their image as an example. There's no reason it has to be a negative experience for anyone.I've felt that the stars in some of my recent 127 Mak DSO images were quite bloated, but I'm also coming to the conclusion that it is the optics that are the cause. Particularly as I found out a few nights ago that the collimation looks really unpleasant as stars move further off-axis.James Link to comment Share on other sites More sharing options...
