Hi Don, that is really interesting! I will try that out. The diamond shaped stars of the minimum filter are really bad. I usually have to fade a lot when I...
Thanks so much Steve! Clear skies, Kevin From: Steve Mandel Wonderful, Kevin! a great perspective on this area. Your hard work paid off nicely! Steve _____ ...
Hi all. I'm really missing all the great winter emission nebulae. My light polluted skies make decent galaxy imaging a daunting task with my setup. I feel...
This nebula in the heart of Auriga is rather faint considering how bright it looks in this image. I used CCD Stack to register and combine the images using...
Like I said, no real problem <g>. ... http://www.stonecreekobservatory.com/Galaxies/M31/index.html ... www.flemingastrophotography.com Direct from Boston -...
For longer focal lengths, there are some spring-time planetaries. Here is my Jones-Emberson 1 in Ha, I think it's still around for a few hours each night: ...
I shot some frames of the owl nebula two nights ago in narrowband 16" LX200R Fork Mount, STL-6303, Astrodon Narrowband Filter, externally guided 80 min each...
Here's a link to a chart of some springtime planetaries: http://www.blackskies.org/seasonbst2.html Kl_22, Abell36, and of course, the Owl, look like...
Terry over on the SBIG group suggested I try a different Palette for my narrowband image and it did produce a more traditional looking narrowband image Seen...
Looks good, Michael. I was getting desperate. ... http://www.darkfireastro.com/images/JonesEmberson1_Ha.html ... www.flemingastrophotography.com Direct from...
Yes, I've resorted to, gulp, galaxies. But, around 3-4am some narrowband targets are starting to come up. Phil ... [Non-text portions of this message have been...
I'm glad I waited to comment. Either version is terrific, but this version does show the structural differences better. Good work, Michael. Don Goldman ...
Hello All! I am off this week, and that is when the weather decides to go sour. I haven't been out with my scope for about 5 days. However, I am still imaging....
Hi, can someone help about where to find a procedure to create a Hubble palette image with just Ha and OIII images? I think this procedure could be placed in...
That will be a tough job, Florencio. The Hubble palette uses Ha for the Green channel - the channel normally synthesized by most folks when supplied with only...
Hi Everyone! I am looking at new cameras and would like to see some relatively short halpha exposures (approximately 5 hours)from someone who is using an STL...
My total exposures are usually longer than that, but here are a few with the FSQ and 6303 chip, Brian: http://www.flemingastrophotography.com/nebulae.html ... ...
Neil, Thank you for the link. When you went from an ST-2000 to the STL-6303 did you notice a lose in detail because of the larger pixel size? Did you do any...
There is a slight increase in undersampling...I believe something like 2.88asp to 3.51asp. Hard to really SEE the difference, though. The big difference is in...
Neil, Quick clarification: the 16803 chips have 9-micron pixels as well. You might be referring to the 16000M chip, which is the one with 7.4 micron pixels....
Hi Brian, you are right, the pixels of the 11000 are a bit too large for a widefield refractor like the FSQ. But I am really impressed what nice details this...
ALL the cameras have pixels too big for our FSQs <g>. Even the outstanding ST-10 results in 2.64 asp. That works fine if you have seeing in the range of 8.7...
Hello All! Happy Easter to All!!! I got a chance to image one of my favorite southern targets, NGC 2070, The Tarantula Nebula. It is an HaRGB, but the Ha image...
