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...
I hope you'll pardon the post, but I've joined GSSP 2008 organizing committee, in part representing imagers, and I am REALLY excited about the prospect of...
NGC2903 has always been sort of a harbinger of the galaxies for me. When I see it rising above the head of Leo, it always brings with it anticipation of galaxy...
that's cool Pete by sheer accident I am imaging the same object tonight maybe I will have something worth showing tomorrow if i wake up early enough to shoot...
Hi, I just got a NP101is but now need to purchase some adapters, as the EOS T-mount does not fit the 2.4 wide focusing unit on the "is". Would the CWT-1070 be...
TV makes an EOS adapter for the IS focuser. It screws in directly to the focuser so is very rigid. Here is the pdf chart for necessary spacers and adapters. ...
Hi Vincent, Thanks for taking the time to research this and sharing it. That EOS adapter is the one I was referring to. The CWT-1070. I was actually wondering...
Rogelio, If you check the chart, you'll see that for an APS size chip with no reducer, you need 2.375" of spacers, which (according to the chart again) are 2...
Hey everyone, Thought I'd send out a reminder, as the registration rates go up April 15th. If anyone is looking for a great venue to image this summer on the ...
