Early on Thursday and Friday morning I captured the 20 and 21 day old moon (full disk) with the MSRO configured as it always is as a deep-sky system. The FOV of the camera is 1.3-deg x 0.9-deg with an image scale of about 0.9 arc-sec/px.  I captured these images using SharpCap. Here is the processed and labeled image(s). You can clearly see craters down to 3 miles (5 km) and detect features smaller than that. For those new to lunar/planetary imaging, this is not the typical configuration. Here I am only shooting at a focal length of 851mm at f/5.1  Typically you need f/20 or greater to get the best resolution possible. I processed these images with Regstax 6, GIMP, and Paint.

I enjoy pushing the resolution on these full disk images of the moon to see how much I can do with our system at the MSRO. Equipment details on the image

Here is a link to the full resolution image

+1  on 'heavy'.

Just as a science project, I bought my scope a 2", 2x ED barlow a while ago.   I mostly wanted to check out how well my guiding held up at longer focal lengths (perhaps with a future scope) and maybe do some Moon work with this one.  This was on a 102/621 mm, so 1200mm -ish FL barlowed, depending on spacing variation. 

Well... I think the guiding held up ok, but the images were hit-and-miss anyway.  By the time I had arranged things to get the back focus I now needed, I had the focuser stretched out pretty much at its limit, with lots of weight from the big glass in the barlow, etc., and my DSLR out even farther on that limb....

The TL;DR is that my mount was ok, but my focuser wasn't up to it, and it's an old JMI two-speed.  The thing's a tank and normally perfectly fine, but that much weight out that far, and it sagged anyway.

That’s about all I can tell you.  I gave it up after one frustrating night.  Didn’t try to figure out how to use it properly.

One other thing is the darned things are heavy as can be.  Look at those specifications.

Hi,

last week I had the chance to made some pictures (videos) of Mars. It was my first attempt with Mars and it was also the first time were I could test new hardware and settings together. So the Mars was not my first goal, but at the end I’am surprised, what is possible.

BTW, I noticed, that Explore Scientific offers focal extenders. Are there any limitations in use with different telescopes? I’ve only a cheap 1,25’’  2x Barlow… so I think about a 3X 50,8MM/2“ or the 5X 31,7MM/1.25“ for my Skywatcher 80/600. If anybody has experience with this, any hint is welcome.

Regards, 
Mirko

User Manual for Android version of ExploreStars? #ExploreStars #Android #VIDEO

Paul Mogg
 

Hi there, is there a user manual available that is specific to the Android version of ExploreStars? I'm a beginner to astronomy equipment so I need exact instructions as to how these things work, and so far have only been able to find instructions for the Windows version, instructions for installing the Android version, but no user manual for the Android version, which has a lot of differences to the Windows version, e.g. star alignment, new "ENTER" and "OBS" buttons, different functionality on the "SYNC" button. How do you you capture a location?. I know you can work these things out by trial and error, but frankly you shouldn't have to guess and waste your time doing that. Thank you.

Thanks Wes, I have the FTDI chipset and everything else works fine. I’m sure I will find a workaround I just thought I may have a fault. However it’s a computer isn’t it🤔

Thanks Jennifer I will give that a try.😊

Roy:

I assume you attempted to update the FW using the Configuration Manager Tool.  Another way to update is manually via Command Prompt.  There are instructions located in the PMC-8 Application Note (AN001).

Re: #FIRMWARE #FIRMWARE

I had the same problem.  Unfortunately I do not believe there is a cure, just a work around.  

1.  There was a suspicion that it had to do with the ftdi or lack of an ftdi chip set.  I had the failure with both I believe .  But I might be remembering it wrong.  If you are using a non ftdi usb-serial adapter then get one with the ftdi chipset.  If you are an iexos it already has it in there, so look at the next point.

2.  What worked for me was to change the pc being used to load the code.  Not ideal I know.  I couldn’t get it to work using my windows 10 tablet.   It did work in a bootcamp Mac air, and it works fine on my Dell laptop.

Sorry man, that’s all I can tell you.   Find another computer.

Hi All. I am having issues uploading the latest firmware. I have full control of the mount via serial but the response from the PMC manager keeps coming back 'Checksum Error on Com5'
Is this a laptop issue or a PMC8 issue. Here is the log from the PMC manager for each of the uploads.

Any ideas?

Thank you Wes this is the information I needed it will help a lot.

Thanks again Bill.

Re: Polar alignment and Sharpcap.

Wes Mcdonald
 

Bill:

1.  If you are polar aligned by sharpcap, you have gotten your RA axis parallel with the axis of the earth.  That is step one.
2.  If you are polar aligned, there is in principle no reason to do a 2-3 star alignment. Clear the alignment results in Explorestars and use the mount raw.
3.  If your mount is truly level, especially now east-west tilt, that is step two
4.  If you have cone error, meaning your telescope is not parallel with the RA axis, best to visualize when you are at polar home, your goto accuracy will be poor to the extent you have cone error.  It is best to calibrate out cone error if you need very accurate gotos.  This is done per a video from the Astronomy Shed (https://www.youtube.com/watch?v=WatdQlPp22Y).  This is step three.
5.  If your polar home position is not correct, then your gotos will be off.  You should establish the true polar home position.  I have a paper in the Files section of the Mounts subgroup that shows you how to find polar home.  It does a pretty good job I think, although some have reported variable results.  This procedure answers your question about where the weight bar should be at polar home.  The arrows are close, but may be off for your specific mount and setup.  Note the correct polar home is affected by the level, so establish a way to repeat your level every time.  This is step four.  Note you must restart the PMC8 with the mount at polar home after you do your sharpcap alignment to ensure the PMC8 has the correct north celestial pole ( NCP) reference.
6.  After you do your first goto and center the object you should SYNC your mount.  This will remove most if not all of the RA home error you might have, but DEC disturbances caused by residual cone and level are not removed completely except near the location of the SYNC.  Thus if you are having trouble getting deep space objects in the eyepiece, do a goto to a nearby star, center it using your red dot finder and eyepiece, and SYNC.  Then do a goto to the DSO you want to see.  It will be near about dead center.

The issue Wolfgang mentioned is that if you run the 2-3 star alignment in Explorestars and center the incorrect star, you are not going to get a good result.  All it takes is one bad star and the result is bogus.

The 2-3 star alignment is useful in that it removes RA home error, corrects for level errors, and will also correct for polar alignment error.  It does not do cone error or DEC home error correction however.  

If you have a good polar alignment but your goto is poor, you can still track objects very well, once you find them and center them in the eyepiece.  

I tried to address all of your points. Hope this helps.  2-3 star alignment just takes practice and you do need to get proper set up with respect to DEC home and cone error.

Wes.
