Last night I took advantage of clear skies and imaged from home again. I was out there from about 9 PM to 4 AM. I used a small RavPower battery pack for my laptop and my new (light) 200WH Portable Generator for my scope and camera. I was pleased to get about 7 hours out of the two!
I continue to get a bit better at getting where I want and what I want with regard to imaging. A few things I want to keep in mind below (i.e. note to self):
Before beginning, use eyepeice and make sure image will be centered. StarSense will do this. Go to known star, center, and press Align - etc. After centering, press Back to continue.
To focus, slew to object and focus on set of nearby stars. On my FeatherTouch focuser, the camera will be focused about 80 mm. Set Video mode to about 4 seconds exposure and make sure Stacking is OFF. Use the FWHM (Full Width Half Maximum) AND visual to optimize. Looking for the smallest FWHM (range 3 to 5 is good). Make sure to allow A LOT of time between focus adjustments - especially at the beginning of the session. Watch for the "jiggle" and the green status bar at the top to know the image on the screen is updated. Plan to focus a bit after moving.
The Infinity software seems to freeze on me. I think it froze about four time during this session. A work around will be (maybe) to be sure and record the session so it can be processed later. Also, save images as they are stacking.
To get best image, turn on the Fine Histogram option near the bottom left menu - select black, orange, white.
Take care when slewing between objects. If there is concern telescope might run into mount, manually slew scope to approximate location and then use goto.
One BIG thing I think I did find out is that the presence of wispy (high-level) clouds will add a grey / white background to stacked images - this makes sense.
All-in-all, I'm haveing a BLAST viewing "stuff" from home like this. Things just don't pop out or can't be viewed without stacking. It's SO enjoyable watching images "come alive". It's also "fun" playing around with the histogram while gathering those cute little photons =)
So my husband is like... Your new Horizon camera will not image planets? You should get you something so you can image planets <3
So.... I (we) purchased the ZWO ASI 120 color camera. I'm still finding my way around - but VERY FUN! For these photos I used SharpCap software to take the images and then AutoStakkert to stack the images.
I made the leap from a DSLR to a CMOS.... A driving force for expanding in this way is to be able to share with others live images, sometimes called EEA or EAA - Electronically enhanced astronomy or Electronically assisted astronomy.
I'm using the Atik Horizon Camera attached to my 6" Celestron Advanced VX. I've had to use a 2" extension tube to get it into focus. There are other tidbits I'll probably mention in later posts, but for now ~ here are a few photos I've taken so far =)
Globular- M10 (I'm pretty sure....):
Wild Duck Cluster:
I'm looking forward to "playing around" with this camera more! I LOVE seeing the images stacked in real-time. I hope others will enjoy the capture in video mode too ;-)
I'm wanting to project from my telescope onto a monitor, as I saw recetly done at a Public Viewing session at the Witte Observatory by a visiting member of the Popular Astronomy Club (PAC) =)
A bit "quick and dirty" - I set up our "adopted" 8" Star Hopper (Newtonian refelctor on Dobsonian mount). I played a bit with it during the day both prime focus and projection using my Cannon ti5. I was not able to get the camera close enough to the secondary mirror to get it to focus using the prime focus method.
I was, however, able to get the Moon in focus using the projection technique with a 17 mm eyepiece. =) I had to back the camera WAY OUT. The image was hard to image because I had to hold the camera steady as the mount could not support its weight.
Here are a couple of images I snagged and a video I made.
The monitor we ordered came in and I hooked it up to take a look at the Sun through my 6" Celestron Advanced VX Refractor. The image on the monitor worked pretty darn slick. I used the projection method through a 20 mm eyepiece. In order to get the travel I needed, I had to add 2" extension to get the image to focus.
Here are a couple of images and video I made. I was glad there are (finally?) a few sunspots to look at.
