Thanks. I'm of the same opinion. I think that I must have tried something similar to this at least four times now, but eventually I might get it right <g>. ...
yeah i have been having fun shooting familar objects on the few nights I have had some skies to work with. i have had a few more than I did a year ago but...
All, I have just received a new optical tube and have noticed something that I find perplexing. Any thoughts from the group would be appreciate. First the gory...
the fainter the target the more you have to push the processing and the more you push the processing the better your flats need to be cleaning the cover slip...
Richard, Thanks for the good information. I am going to try and get some better flats this evening. What prompted my question is I took a bunch of integrations...
you should not have to worry about this if the flats are good; the fixed pattern noise will be corrected by good flats. the trick is getting the good flats. I...

I found that file I mentioned. it shows the total noise in a corrected (calibrated) image as a function of total signal level and the amount of signal...

Thanks for posting this Bob. I am looking forward to the conference and discussing a number of new things I have been doing lately that I have not yet publicly...
Thanks for asking Dave I will answer inline below and am cross-posting to Narrowbandimaging, where I had posted the same curves from Janesick ... From:...
Narrowbanders, Jim Burnell asked me to post this message. Looks like another good conference coming up in April, followed by the ever popular NEAF. If you're...
I am not Liebrecht but I think I know what he means NB = Narrowband = emission line I think he meant using the major emission lines reassembled and placed into...

normally I would regard a read noise of 7.6 electrons to be pretty good for the average amateur astrocam. But in some situations with faint objects, very...
Hello, My name is Wolfgang Hitzl, I live in Austria and use a 80/480 TMB Apo with a starlight sxv-h9 for astro-imaging mainly for H-alpha. I am interested to...

depends on the object i haven't heard of any online [OIII] catalogs but there are a growing number of amateur images shot with emission line filters you can do...
Hi richard, thanx for your quick reply. BTW, I like your background with the curve and surface integrals. Are you a physicist? wolfgang ... -- Using Opera's...

For those who may be interested....I spent tonight trying out an ATIK 16 cam as a guide cam....it's a cooled CCD cam with an "st 7 " sized chip...tho a sony...
To add even another option for those not wanting to break the bank on a guide camera, I've been using the Meade DSI and DSI pro in my observatory and out in...
I did a bit of imaging last night; couldn't resist the dark and clear sky, and warmish temperatures I was pleased to find good seeing too. Well good until the...
Last month I was about to capture 17x600s on the Jelly fish area. http://astro.neutral.org/imagehtml/20070202_ic443.html And this weekend, the Seagull Nebula...
both very nice Tom good to see images again. perhaps all of us are getting a break in the weather? ... From: Tom How To: narrowbandimaging@yahoogroups.com ...
The DSI's are probably the cheapest on the market at the monment, and work great. I've been using my Lumenera LU075 occasionally as a guide camera only because...
I haven't tried it but I understand that you don't even have to have the camera talk directly to the mount if you are using ACP. It can communicate to the...
And of course, let us not forget the humble webcam. A long exposure modified webcam makes a useful guider. If the colour CCD is replaced with a black and white...
I like both of those very much. You have done very well for any exposure time. I like the comment about "thuggery in PS", but you have apparently minimized...
