this is a great "challenge" object for my mag 3.2 skies in my backyard. I am shooting this in pure emission line so far and have 7.5 hours of halpha, 7 hours...
maybe 100 hours is overly ambitious :-) http://www.narrowbandimaging.com/3c461_cassA_mk1sn2_cm10_geg_cs4_s2hao3_page.htm i evened out the exposure time: 7.5...
Here's an image of M31 I took on Sunday night from Fremont Peak. With 92 minutes of exposure I expected a little more detail, but perhaps at 200mm FL one can...
I've been considering the purchase of a secondhand STV in order to offload the autoguiding duties from my imaging laptop. I have been using my ST-8XE's...
the major technical downside is using automation software to control the imaging session: to dither the automation needs to stop the guider and reacquire a...
I'm unclear about this dithered guiding, and am not currently using it AFAIK. Please explain. Paul ... __________________________________________________ Do...
OK, the STV is not "computer controllable" as such. You cannot have a computer start and stop the imaging, but as I understand it you can download images from...
Okay, that makes sense. I have the latest ver of Maxim and checked it out, discovered the dither feature. I'll have to check this out. There are two dither...
i dont use maxim 4, i use maxim 3.21 so i get my dithering via my automation script engine if you dither by mount then you are going to either need ascom or...
I added some RGB data to my M31 collection, to go with the Halpha I took last month I made three different color images from it using slightly different...
Hi Richard, Nice image! Great subtle use of the Ha data in the Ha+RGB. Didn't know you had a FSQ, but it seems be working well for you - the stars are ...
I decided to try my hand at narrowband imaging. But it seems like the image is still very noisy even after dark subtration. Can anyone see a problem? ...
where is the image Vincent? what are the exposure specifics? with an St10Xe you will probably need to expose 30 minutes or 45 minutes on many of the common...
Watch out for links like this one below - if they have a lot of encrypted numbers they are probably a temporary link, and will expire, which the one below did....
Hi Vincent, I tried to open the image, but I didn't have any luck (even after downloading the file). Could you put up a copy in some other format (ie. a JPEG)....
the FIT version downloaded just fine for me you need more exposure time that's all that is wrong with the image try for 45 minute subs ... From: kmvhuang To:...
Thanks, I'll give it a shot. Vincent From: norcal_ai@yahoogroups.com [mailto:norcal_ai@yahoogroups.com] On Behalf Of Richard Crisp Sent: Sunday, December 09,...
Thanks for the JPEG Vincent. I'd agree with Richard - the technical aspects (focus, tracking, composition) look great. All you need is more exposure time -...
in fact, gentlemen, i have examples of a single 600sec halpha shot taken with an ST10XE and an AP155EDF f/7 I had one of the original Schuler 9nm filters. By...
Richard, Your's has none of the strong noise I get in mine. You'll see it towards the bottom and on the right half of my image. Mine is even a class 1 chip....
no but i used a 9nm filter and that lets more everything through that was also at fremont peak on a very clear night and those objects are comparatively bright...

look in Vincent's folder in the files section and you can see the difference in the QE for the microlensed and non-microlensed versions of the KAF3200 as you...
Ok. guess I need to setup again and give it another shot. I had to tear down because of the wet weather recently. Vincent From: norcal_ai@yahoogroups.com...
