Hi folks had this put to me to by a astronomer relation of carols. . I had discussion about starting this forum and it was said that we are basically camera engineers and not astronomers and that a our images are not anywhere near the quality of dslr image's. . I pointed out most dslr shots are stacked and without post processing are not any better than a single frame taken from an avi video.. I also pointed out that we do not require the same exposure/ intregration time as a dslr.. Seems to him we flaf about to much..I disagree when our kit is set up I think we would be done and dusted long before a canon or nikon has the shots we have...whats the opinion folks

I would flip that on him and say we are much more astronomers than imagers are! We observe while capturing whatever we want. Imagers set up and observe nothing...well maybe their scope... not the sky lol. Im pretty sure i could get some fancy images myself. But im not interested in post processing at all. Just the live dirty views that can be instantly shared with others

video and Dslr or single shot camera's are two completely different aspects of this hobby. and for faffing about, we can electronically view dozens of DSO's while they are still capturing their first image. I know in our club some members can spent four nights or even weeks on one object collecting data and spend maybe double that again processing. whats the fun in that. I love the fact that I can slew from one object to another in sec's and start viewing. What you should of said is that what we do is to replace the eyepiece and view it in colour instead of a grey smudge in a eyepiece,
then smack him in the mouth and knock some sense into him

Your friend is pushing the limits calling himself an astronomer. Photographer and data processor would be more appropriate and if he's using PhotoShop then add artist. Like many that are unfamiliar with electronic viewing he is generalizing and possibly looking down his nose at those not as sophisticated as himself. What he doesn't realize is that in his league he is looked down on by those with astronomical grade cameras.
A smack in the mouth may be a bit harsh unless you are on a hockey rink but an occasional poke in the eye does them good.

A deep breath and a pause is required at times...we can all be defensive about our hobby and yes it does annoy..but its a valid topic for a forum..another thing that was brought up was most of the astromers that image use large aperture scopes 10" and above while we use small aperture and focal reduce as well.. Video astronomy has grew leaps and bounds but still has negative views by diehard astronomers and imagers.. Each to there own me personally I like to try and do it all ..visual..astrophotography and video why is there still biased opinions seems you have to one or the other in astronomy

we are basically camera engineers and not astronomers and that a our images are not anywhere near the quality of dslr image's. . Obviously a rash statement from someone who knows little about astronomy. Astronomers basicly falls into 3 categories. Visual observers, Imagers, and electronically assisted observers. They all study the universe in their own way but are all astronomers. Visual astronomers can study the universe through an eyepiece for a lifetime and never see what a camera can. Imagers can spend a lifetime gaining enough data to produce a spectacular image but without ever looking through an eyepiece. Electronically assisted observers can study the universe in real time with enhanced viewing capabilities and see more than the other 2 in far less time, and still never look through an eyepiece. I would imagine that Carols relation also thinks DSLR's are the proper tool for the job. Do they know that a dslr is just a poor mans CCD camera and is vastly inferior to a proper cooled CCD Cam. I aslo watched TOM(Soin)'s broadcast yesterday morning and saw the best M51 ever produced with an MCX X2. It was actually highly detailed and very clean. You could counter this relations uneducated remarks by mentioning that dslr and ccd imagers are actually just photoshop experts and not astronomers. The only true astronomers were the original ones like Messier, Herschel and the likes of Patrick Moore, but given a mallincam in their day, I think they may well have used it willingly. And as for faffing about too much,,,,,,,,,,, ok I admit it.

Not sure I get the camera engineer bit? Imagers mod DSLRs and cool them. It takes less time to setup video than a long exposure session I would think? As for not being astronomers, I. Would think we are more so looking at live objects rather than waiting days on one object, but each to their own

I like video because of the instant feed back you get from the camera, but at the same time I enjoying capturing and processing images.
I would like to have a astrophotography setup and collect data with a dedicated ccd camera and then use my 10" goto dob to view live while im waiting for long exposure to get done.
I really like both. My next telescope is going to be for astrophotography and use a mod canon dslr.
Video astronomy is great astronomy outreach and education.

Horses for courses Davy, we all like different things and what suits you best is best! Tell your buddy I'm going on NSN soon so perhaps we can change his opinion

What a Clown! Most astrophotographers never look through a telescope! They set it up, turn the PC to 'capture X amount of frames', then go inside and watch TV, have a shower, eat their evening meal, then maybe walk outside to check they haven't got cables wrapped around somewhere. I know, because that's exactly what I did for years and it bored me. Some I know actually click 'Capture' and go to bed! Yep, sound like Astronomy to me Video Astronomy is viewing, observing, looking. Now that's Astronomy. Sounds like he is confusing it with 'Imaging'.
