Bit of a lurker here but time for a first post as I've scoured every corner of the internet and cannot find the exact info I'm after.
My style of shooting is more landscape astrophotography over deep space and I really want to be able to photograph Orion using a wide angle lens (eg. Samyang 24mm) on either a Canon 6D or a Sony A7SII and pick up the nebulosity.
I have a tracking mount (Star Adventurer Mini) and am familiar with stacking images. I was wondering if a light pollution filter would help my cause here as I've read they can help boost nebulosity.
Started to get my head in a twist with all the various filters and different types of nebulosity. I really don't want to modify either camera as I use them both for daytime landscape work too.
The Samyang 24mm has a 77mm thread on the front, would something like a Hoya Red Intensifier be beneficial to my aims? Is there a better front threaded filter available for what I want? Or is a clip-in filter better?
Any help much appreciated,
Quite often I will start an image and not get time to finish it before the telescope being used has to move on.
That is the case with this one, which is just 3 test exposures with a small refractor and Atik 11000. Usually the data just sits on my hard drive, going nowhere, but by chance I opened one of the exposures in Pixinsight and hit CTRL+A, and the auto-stretch feature revealed a bit more detail than I expected, so I just stacked the three images with no rejection to see what came out. Originally my intention was to frame a shot of the three main stars in Orion's belt, but the nebulosity and position of the horsehead nebula did not lend itself to a nicely composed picture.
I definitely haven't gone for "pretty" here, but rather, with a drastic stretch of the outlying regions around the Horsehead, the image makes clear the density of the Hydrogen clouds in the area. We also get an idea of the amount of stars that get filtered out by comparing local areas within the image.
Oddly enough, despite a personal propensity for pareidolia, and having imaged this area extensively for quite a while now, and even having a small contribution to this image https://apod.nasa.gov/apod/ap101005.html , I have never before noticed the looming Giraffe in the background.
I shall look out for it in future though
I just got a little clear weather and thought I would try out the Mesu 200.
If you use plate solving to find targets do you have to sync the Mesu 200 in your planetarium software accurately? I read that you have to sync with a planetarium program. Can you just sync and be tracking at a sidereal rate? I'll be using ACP and don't plan on using the SKY X other than for the telescope sync function. The mount is moving faster than sidereal and the stars are moving quick on the frame and focus screen of Nebulosity. Not enough to blur but you can see movement at the 1 sec I have the camera set to take pictures. What I get in Nebulosity is that after every 1 second exposure the stars move and I can't do a fine focus before they move off the small fine focus screen.
I know that I'm doing something wrong.
Thanks for any help.
