Re: [Utah-astronomy] Ceres and Vesta
...and you probably noticed this as well, but Mars and the 1st quarter moon will also be in extremely close conjunction on July 5th. I don't know precisely how many degrees will separate them, but it looks to be about 1/2. Great night for a single field of view! ~Kelly

The current issue of S&T notes that Ceres and Vesta will be within half a degree of each other between 29 June and 12 July and closest at only 10 arc minutes on 5 July.
By coincidence there will be a SPOC star party on the 5th and I'm looking forward to using the Bogdan and its just over half degree field to see two relatively bright minor planets in the same FOV.
If I've got my figures right on that evening the two will be 39 degrees up at the start of nautical dark and 32 degrees at the start of astronomical dark.
Now having said all that, I'll predict rain the night of the 5th... :)
Also, unrelated to the above but related to an earlier thread here on terminal velocity, here's a fun video a few friends shot a while back.

I'm thinking that with the right amount of streamers we could do the same with a bowling ball. :)

Correct. I'd not noticed that. Looks like closest, 24.5', for here at SPOC is at 1830 MDT with Spica about 4 degrees from the pair. At that time the Sun will still be up but we might still be able to spot Mars by scanning just above the Moon. By the time civil twilight starts about 2130 the two will be about 1 degree apart. patrick On 27 Apr 2014, at 05:36, Kelly Ricks <kellyalenericks@gmail.com> wrote:

Just remember that Mars will be well past the prime observing window for this opposition by then, only around 9 seconds of arc in diameter (estimation on my part), and noticeably gibbous, so we'll need exceptional seeing in order to make out surface detail. If you want to see Martian detail, look now, as it is receding from earth and getting smaller every day until next opposition in 2016.

I’m going to try to image Mars sometime this weekend. However, my imaging capabilities as regards planets is pretty meager. Hell, all my imaging skills are pretty meager, but planetary imaging really sucks. That’s why I’m going to give it another million or two tries to try to get it right before I give up. Weather looks good down here this weekend, though. Seems to good to be true. Now I’ve done it. Dave On Apr 28, 2014, at 5:47, Chuck Hards <chuck.hards@gmail.com> wrote:

Dave, shoot video, and lots of it. You'll be bound to have enough good frames to put together a terrific image. But yes, by announcing your plans in advance, you pretty much jinxed the weather. On Mon, Apr 28, 2014 at 7:54 AM, Dave Gary <davegary@me.com> wrote:

One thing to note about observing right after sunset. There is often a window lasting anywhere from five minutes to as long as 40 minutes, right after sunset, when the air is remarkably still and seeing is excellent. The sky is still blue, so you can't look at any faint fuzzies, but lunar and planetary observations are possible. Apparently the ground hasn't begun to give up the heat it accumulated during the day yet. Sometimes this window doesn't appear, but often in summer it is there, briefly. I took advantage of it when observing the Shoemaker-Levy 9 impacts on Jupiter. I got some incredibly good views for up to 40 minutes after sunset, before the air started boiling and seeing went downhill until well after midnight.
Thanks for the information Chuck. I do have a little video camera. I’ll try imaging right after Sun goes down on Thursday. Dave On Apr 28, 2014, at 8:20, Chuck Hards <chuck.hards@gmail.com> wrote:

You may be better off waiting until Mars is higher. The sunset suggestion was mostly for the July 5th event Kelly posted about. I've used both my hard-drive camcorder and the DSLR for video, both seem to produce the similar results on the moon, sun, and planets. It's the stacking and post-processing that gleans all the details. On Mon, Apr 28, 2014 at 9:05 AM, Dave Gary <davegary@me.com> wrote:

I had planned to start imaging around 21:30. I think Mars is at about 40° above the horizon by then. I think. It may be a bit lower. I’m going from visual observation (memory) the other night when I got called out. Dave On Apr 28, 2014, at 9:21, Chuck Hards <chuck.hards@gmail.com> wrote:

My apologies if someone has already mentioned this - If you are using a color video camera or using your DSLR (in video mode) you should check out the last article in the May S&T. It has some really good info about new algorithms used for debayering. This should help give you better resolution for planetary images (when starting with color video).

Thanks for the tip, Dale. My May S&T has been sitting there for a week, unread, your post reminded me that I needed to open it up. Interesting article, although I'm having a brain cramp when thinking of how to apply the masking/layering to planetary video frame stacks. Give my brain a kick-start, please!

Hi Chuck, I think typically you would be dealing with AVI format video files. You can also use other formats (FITS, JPEG, etc.) if you have single frame imagery. The bayer masking is performed by the camera. From there you can use the enhanced techniques the article discussed to debayer or you can pipe it into Registax or other stacking software.

Dale, I do imaging so infrequently that I have to re-learn the software just about every time I use it. The older I get, the more repetition I need to learn, darnit. I've only had the DSLR for about six months and I'm still not all the way through the manual. It's a whole different animal than the HD hard-drive video camera. I'll be getting a new computer in the next month or so; I may hold off on processing anything else until I get the new one up and running, and all the software installed. Image files are getting so big now that it takes my old XP machine forever to process stuff, let alone just uploading files! I recently started storing all my video and still image files on an external hard drive, so it will be easy to just swap that out to the new machine.

Hi Chuck,
I think typically you would be dealing with AVI format video files. You can also use other formats (FITS, JPEG, etc.) if you have single frame imagery. The bayer masking is performed by the camera. From there you can use the enhanced techniques the article discussed to debayer or you can pipe it into Registax or other stacking software.
Personally, I'm just getting started with this stuff.
When taking video of plants can you use a DVR camera like a Nikon D3100 thru the telescope or like a web cam?

However, my imaging capabilities as regards planets is pretty meager. Hell, all my imaging skills are pretty meager, but planetary imaging really sucks. That’s why I’m going to give it another million or two tries to try to get it right before I give up. Weather looks good down here this weekend, though. Seems to good to be true. Now I’ve done it.

Just remember that Mars will be well past the prime observing window for this opposition by then, only around 9 seconds of arc in diameter (estimation on my part), and noticeably gibbous, so we'll need exceptional seeing in order to make out surface detail.
If you want to see Martian detail, look now, as it is receding from earth and getting smaller every day until next opposition in 2016.

Correct. I'd not noticed that.
Looks like closest, 24.5', for here at SPOC is at 1830 MDT with Spica about 4 degrees from the pair.
At that time the Sun will still be up but we might still be able to spot Mars by scanning just above the Moon.
By the time civil twilight starts about 2130 the two will be about 1 degree apart.

...and you probably noticed this as well, but Mars and the 1st quarter moon will also be in extremely close conjunction on July 5th. I don't know precisely how many degrees will separate them, but it looks to be about 1/2. Great night for a single field of view!

Ed, you can use a DVR camera with the telescope, I've done it many times. Use it afocally, meaning you place an eyepiece in the focuser and focus normally, then position the DVR lens as close to the eyepiece as possible. Long focal-length eyepieces work best for this. Use a Barlow if the magnification is too low. If you don't have an eyepiece projection adapter that fits your camera, there are universal brackets made that hold the camera in the proper position, such as this one, which I have used successfully: http://www.telescope.com/Astrophotography/Camera-Adapters-T-Rings/Orion-Stea...
