ISS Transit 4/16/16

There were 3 cameras connected to my mount, 2 of the cameras were connected to telescopes and 1 was riding piggyback. Fortunately or unfortunately only 1 recorded the ISS transit. Elliot Sevren's photo shows the setup. There were 56 images (layers) of the ISS combined in Photoshop to make the composite.





                                      

The Moon: Canon T3i vs. QHY-5L-II-M

I took series of videos of the moon using my Orion ED80 f/7.5 refractor on 4/20/16.  I first took the videos with the Canon T3i controlled with Backyard EOS and then switched to the QHY-5L-II-M Planetary Imager in an effort to see which gave better results.  I processed the images roughly the same through Registax and Photoshop.  The results are as follows:

Canon T3i Images: 

Image 1-Prime Focus 2-in (1/2500s, 400-ISO, 1000 frames)

Image 2 - Prime Focus 2-in BYE 5x (1/2500s, 400-ISO, 1000 frames)
Crator: Plato - center top
Maria; Sea of Rains - center

Image 3 - Prime Focus 1.25-in 3x Barlow (1/640s, 400-ISO, 1000 frames)
Crator: Tycho - center bottom with striations radiating outward

Image 4 - Prime Focus 1.25-in 3x Barlow BYE 5x (1/800s, 400-ISO, 1000 frames)
Crator: Plato - center left

QHY-5L_II_M Images:

Image 1 - Prime Focus 1.25-in (500 frames)
Crators: Copernicus - center, Plato - center right, Grimaldi - top left

Image 2 - Prime Focus 1.25-in 3x Barlow (500 frames)

Image 3 - Prime Focus 1.25-in 3x Barlow (500 frames)

Image 4 - Prime Focus 1.25-in 3x Barlow (500 frames)
Crator: Plato - center 

Both cameras did well and they are close.  However, I think the QHY-5L-II-M gave slightly better results especially with the closeup views.  None of these images were cropped, only the brightness, contrast, exposure was adjusted in Photoshop. The QHY-5L-II-M Image 4 showing the crater Plato was rotated so it matched T3i Image 3.

Image 5 - Prime Focus 1.25-in (1000 frames)
Image 5 was taken on April 16, the night of the ISS Transit through the Orion 80 mm Short Tube refractor.  I had this recording but it shut off right before the transit occurred. Fortunately I got with the Canon T3i mounted on the Orion ED80.  For a comparison of ED80 vs. the ST80 look at Image 1.

Imaging Jupiter with and ED80 (80 mm)

I have been trying to get a higher quality image of Jupiter with my Orion ED80 80 mm refractor for quite a while now.  I have tried various setups this past year which I will describe but I believe I have found the optimal configuration (Figure 1).

The main difference between this image and other images I took with the ED80 over the past year was using an Explore Scientific 3X Barlow which is why I requested it for a Christmas present.  Another difference was recording in 5X Planetary mode in Backyard EOS (BYE) although I have other images with just that mode and they are not nearly as good.

For comparison, I have added some the other configurations that I took previously with the ED80.

First Shot of Jupiter from the BMAS Observatory

This was the first shot of Jupiter from the rebuilt Boothe Memorial Astronomical Society (BMAS) 16-inch reflector. It was sky not ideal for planetary imaging as there was lots of atmospheric disturbance, also Jupiter was not overhead so images are not as clear as they could be.  I published an image a couple weeks ago based on 1000 stacked frames.  However, another BMAS member, Elliott Severn, informed me that I could could combine all three 1000 frame video clips in Registax if I convert them to single frames. Since I use Backyard EOS (BYE) and BYE already creates single frame jpeg's along with the video clip it was easy to bring them into Registax.  Another program I used prior to Registax was Planetary Imaging PreProcessor (PIPP) which among other things, can cut down the size of the file Registax has to work with. So here is the newly reprocessed image.

Image 1 - Reprocessed (1950/3000 frames)

Image 2 - Reprocessed, Cropped to the same Size as the Original Image (1950/3000 frames)
