Gras___ Don't be fooled

Hi all,
After 2 sessions and 3 photo's using this ----Don't be fooled!!!!!!!!!!
The photo's shown when you log in are not what you will get!!!!!!!!!
Whilst i'm a bit dissapointed i already knew, my point is don't go hoping for a you beaut photo, it will not happen.
However it will give the budding astro-buff something to beat.
Cheers,
Duncan

It does say they are not realistic representations of what you'll get doesn't it?..you're talking about the G13 trial I assume

Duncan,

Did you tell the guys first ?

After all that is what the trial is all about.

Cheers Rally

Can you tell more what you mean? I was thinking about paying for time but now not so sure. Very expensive if you images are not good as they are saying. Thanks

Duncan it's a bit rough to say something like that without elaborating on it more.. Have you followed the other GRAS threads?

Hi Tino,

This is a photo from Jase http://www.cosmicphotos.com/gallery/...ld_album_id=12, partially aquired from GRAS. Definately you can aquire fantastic data using their equipment. The processing of course is up to you.

The current GRAS 13 trial is fun but GRAS 13 is aimed at a different audience and is still only in BETA.

LOL, I like it . Your a hard man Duncan. Sure, show us you can beat it.

G13 is a freebee tryout, you get what you pay for .

If you pay, it gets better, way better .

for what it is G13 works well, you just need to understand whats going on before you pick a target, as you are only getting a single 5 - 10 minute colour exposure from a widefield scope and a low QE ccd you need to pick the brighter extended objects to get a good result.

the way G13 is set up its more a happy snapper than a full on imaging rig.
i think people are expecting way too much from it from seeing some of the other images acquired from other GRAS scopes.

Regarding my experience with Gras, I didnt use this new one rather the big RC one in Australia, took 2 objects with it, first one came back perfect, a set of Lrgb images. 2nd object I took 3 luminance shots, all had massive guide error, not something I thought Id see from those horrendously overpriced paramount mounts. If I was able to fit a buyers drive worm and wheel to my old Sampson mount, I reckon it would leave those paramounts in its dust as far as good tracking goes

Hi all, Don't be to critical of the results you are getting. Being a new owner of a CCD imager I found myself in a really frustrating position with this new camera. My real problem has been and still is getting the quality image I have taken into an image which looks good. There is a really steep learning curve with ccd IMAGE PROCESSING. The cameras record a bucket full of data and without good processing skills you get a drop of image. Without the help of a lot of very gifted processors I would be using my camera as a boat anchor.
Go to Brad Moores web site and take a look at the processes he uses and you will see a great image can take literally hours of processing.

You may very well have the data but be unable to extract it very well.

This is not meant as a slight on your processing skills but may be an explanation why your image is not what you had expected.

I have a mate who has a 6 thousand dollar SBIG and he has been through the same frustration.

Keep your original data and only work on copies, given time you may find your initial post was wrong.

Keep at it

The PME woulnt be the problem, cloud etc could have been . If your not happy, GRAS offers a no hassle refund. Many factors can contribute to an unsatisfactory experience. Please contact GRAS support if you have a problem.

Hi all,
Don't get me wrong. For what it is it does a great job.What i'm saying is that when you select a target there is this you beaut photo beside it and newbies will expect that in return. The reality is far different and could cause major dissapointment. Those of us who have been in the hobby for a while realize that to get clear in depth photo's you need heaps of exposure on heaps of frames to stack together.
My son was beside me when i used it and was clearly dissapointed at what we got. I had to explain to him why it didn't look real good. Having said all this using it at 2:00am would be a lot better than 9:00pm.

If i have upset anyone i do apologise. More education is needed along these lines.
I will be in contact with the Gras team later to see if i can gain more info to give my lad and convince him not to be so dissapointed.

I for one will be buying time with these scopes. Mainly because i work away for weeks at a time and get limited time with my own scope. As i said to my lad, Pick a target and image it over and over again and then we will stack them to see a much improved image. And hopefully he will enjoy what he can do and achieve.

Again i do apologise if i have offended anyone.
Cheers
Duncan

Hi Duncan,

Thanks for your comments let me address some of the issues you raise.

1. I stated on the menu selection screen this " The target icons displayed are indicative of a long exposure imaging sequence with moderate to advanced image processing applied. G13's results will differ from the icons displayed."

I'm not sure how you got mislead on the expected results. So based on your comments I have now high lighted it in BOLD RED.

Additionally I have now included some sample images on what you should expect out of the system. Along with some samples of what to expect out of the other telescopes assuming your processing skills are up to scratch.

As you say anyone who knows anything about astrophotograhy will know the exposures are too short to produce draw dropping images. Most who have tried astrophotogray knows how much work goes into even getting images to this standard little along being able to click just your mouse at whim and end up with 4 images in your inbox. It was my decidsion to limit the exposure as to give everyone a fair go and to make it as simple as possible for all subscribers.

Here is a good example if your have the right skills where gras can take you.
http://apod.nasa.gov/apod/ap080502.html

However just because you have access to the GRAS gear doesn't mean you can take nice images, because its how you process the data you have.

However not everything is about pretty pics, a larger percentage of our customer work with the AASVO and the Hubble Space telescope if you really want to get serious. We have working groups right now doing these sort of projects.

http://www.prweb.com/releases/2007/11/prweb571706.htm

2.) The reason for selecting the these thumbnails for G13 is to give the novice users some idea of what they are going after, nebula, galaxy.

a) Firstly it was impossbile for GRAS to provide a scalled down thumbnail as no image data exisit for the service until now.

b) If you do take the G13 image shrink it down to a 80x80 thumbnail its impossible to see what you are going after. Is it a glob or a galaxy?
(See attached images)

c) If I used a mouse over to provide a 1/4 size preview of image you should be expecting kinda defeats the purpose of imaging the target, take all the fun out of it.

G13 is a entry level, get your feet wet, have some fun, point and click image system. If G13 subscribers want to trial the rest of the network for a small reasonable fee. Then you can really test your skill in processing images. G13 is obligation free, its going to give hundreds and maybe 1000's of people the opportunity to try astrophotograhy without spending a dime.

Thanks for your feedback,

Best Regards,
Brad Moore

its a small aperture scope (90mm) with minimal zoom. im guessing its designed for wide angle stuff... pleaides would look nice!

i was initially (naively) disappointed (not really disappointed..as it was free.. but you get what i mean) with my image but then came to the conclusion above.

Hi Brad,
Thanks for the reply to this thread.
I did not mean to offend or be over critical. I realize you can't get much from a 10min exposure and did read what was on screen.
My son turned out to be the perfect example of someone expecting a whole heap more. However after sitting him down and explaining things to him (as best im could) He seems to have gotten the idea.
The only shots i've ever taken are of the moon with a point and shoot digital camera afocal. So i've not had any experience taking galaxies or nebula. However after 12mths on this site i do have an idea as to what is involved.
But if what was written has improved the site to better explain to newbies what they can expect then that can't be all bad,LOL.
Again i do apologise if i upset someone!!!!
I have posted some shots i took using GRAS 13 only a couple of nights ago in the Deep Space section and have also stated that i will be buying time.
It is a great thing you guys/Gals have got up and running and can only serve to create more interest in Astronomy as a whole.
Three Cheers to you all!!!. Very well done.

On the flipside i hope to start imaging in about 6/8 weeks. I think i've bought just about everything the other half wanted,LOL.
Heading for GSTAR-ex complete kit and new lappy.

Cheers and thanks,
Duncan
