Re: Keypad not beeping

Well, I hate to suggest this but, for me, I can no longer hear the beep due to failing hearing.  I need my hearing aids.

Nice shot David. 

I have been doing unguided imaging with the Mach2 for more than a year now and I couldn't be happier with the mount and the software tools.  The guide scope and guide camera have been sitting on the shelf collecting dust.

I also imaged the Sharpless 2-155 area.  My view is a little wider than yours though  --> https://www.astrobin.com/udzsan/E/

Re: hi, may i know how many mach2 could be produced every year? #Mach2GTO

Since it could be a while before you could purchase a new mach2, you might look for a used mach1 or 900gto.  Both are excellent mounts and will be a huge step up from your cem60.  You might find you don't even need a mach2 after running one of these.

 If so, would I have major issues if I tried to do regular tracking correction away from the two arcs? 

I dont think so. I believe that if you move to a location beyond your dec arcs that it reverts to all sky for correction, and I assume that if an all sky model is not present that it would just revert to standard sidereal tracking...


Changing the mount motion rate... #Guiding

robert.saint.jean@...
 

Hi,
I am using a AP 900 GTO mount, CP3 and keypad. The project I am involved in ask that I do a scan of the Sun with a spectrograph at various speed. Using the keypad or the ASCOM interface, I currently scan the Sun at 1X and 12X. Is there a way to get the mount to scan the Sun at 6X or 4X ?

Thanks !

Robert

I would bet it’s reflections off some straight surface.  Satellites will usually be much longer.  Meteors tend to be dim on one end and bright on the other, and wider where they are brighter.

It looks like the artifacts on the right are brighter than the ones on the left, as if they are dimmer the farther away from a light source.  If you have a bright light source on the left, are the artifacts on the right dimmer than the ones to the left?

Remove the camera body and look up into the optical train and look down into the camera. Do you see any linear (straight line) obstructions at the edges?

Hi Robert, I should have mentioned these appear on almost all the subs, so it doesn’t appear to be more random events like meteors. I suspect it’s reflections somewhere.

Re: Strange Artifacts -

I think the OAG prism is the problem. The prism is extended quite a way into the optical path. Also, the bottom edge of the prism is not quite parallel to the long edge of the chip. It was rotated 5 degrees or so which would extend the corner of the prism on one side even further into the optical train. I’ve adjusted both and will check it out when I get clear skies again. 

Thanks!

Re: Rookie Question

M Hambrick
 

Thanks Mike

My mistake. I haven't used the Icron in a while and forgot the cabling arrangement. However, when I am using the Icron, the USB cable from the Icron plugs into the USB port on the laptop where I normally plug in my wireless mouse. The mouse then plugs into one of the four ports in the Icron.  If I am using my motorized focuser, the USB cable from the Focuser Boss plugs into one of the other USB ports in the Icron. My cameras are always connected to the other two USB ports on the laptop.

So it sounds like I would have two options for connecting the mount via ethernet cable or one of the USB ports on the Icron.

It does appear to be some sort of reflection. I would check your image train and see if there are sections inside that are not painted black. 

It also appears that you are not in focus as the stars appear as halos.

Topaz DeNoise AI performs very well for me. A friend told me about it back in October During the Mars opposition, and I've made it a standard part of my DSO processing workflow. I also have Topaz Gigapixel AI to resize images, but it takes a L-O-N-G time on astro images, so I do most of my resizing in Photoshop or PixInsight.

I don't understand this. I had an Icron Ranger 2304, and the local unit (LEX) plugs into a _USB_ port, not an Ethernet port. Also, the REX remote unit has _four_ ports. Why so you imply just one ("an") extra port? I'm confused.

True, the LEX and the REX connect with a CAT5 cable, but that does not use an Ethernet port on the PC.

I now have an Icron Raven USB 3.0 extender that connects similarly --
USB3 port on the PC, LEX-REX via a CAT6/7 shielded cable.

I suppose that I
could use one of the other USB ports in the Icron to connect to the
mount. Is this recommended ? I ask because SBIG recommends against
plugging their cameras into USB hubs - even powered ones.
The Icron USB extenders are more than powered hubs. They provide full-spec USB2 ports on the REX -- the Ranger can supply up to 600 mA of +5V on each port concurrently.

I connect to my 1200 mount via RS-232 serial, but I have no doubt the Icron Ranger would provide a solid reliable USB2 connection.

I use a USB 3 hub at my mount and plug in cameras, focuser, serial to USB converter for the CP3.  I also use a GPUSB for guiding since I have a Mac.  I know this is old school but I still want to use my Mac.  I just bring one USB plug into my computer.
