Re: Mounting camera to EXOS2 #EXOS2 #astrophotography

Harry or Jerry,

Will the SkyWatcher adapter Harry mentions connect directly to the top of the mount without any dovetail bar? 

I'm planning to get the Pergear ball head with a 3/8 thread mount connector and 1/4 camera connector.

https://www.amazon.com/TH3-Capacity-U-Shaped-Switching-Vertical/dp/B00MGJH5U6/ref=bmx_4/144-1292665-3442313?_encoding=UTF8&pd_rd_i=B00MGJH5U6&pd_rd_r=181edadb-e09b-4f8a-a9ab-3efbfd83e951&pd_rd_w=BE7xM&pd_rd_wg=gaNi3&pf_rd_p=2876eb4f-6f13-4a84-8c22-9ec887c09643&pf_rd_r=JS75EBFSCHN7YM2C7Q4R&psc=1&refRID=JS75EBFSCHN7YM2C7Q4R

Sorry, as I don't have the mount yet I don't know what's 'on top' of the mount.

You'll probably get a bunch of suggestions. Here's mine:

- I made a wooden Vixen dovetail, long enough to extend back past the mount casting (toward South); then attached an inexpensive ball mount biased toward the rear
(South). The ball mount will probably need a 3/8" screw through the wooden dovetail. Of course, if you have a proper dovetail, it might already have holes. The trick is to
be able to slide the dovetail forward & backward until the mount balances. The included counterweight will be too heavy for balance about the RA axis; you might need a
really small counterweight, like a 2.5 lb, barbell weight. I found that the small barbell weights have a 1" bore, so they fit the 20mm. shaft loosely. I filled in the gap with a PVC
plumbing adapter. A Pair of 20mm. shaft collars on each side keeps it in place,...kinda.

-Then I added a cheap red-dot finder onto the camera's flash shoe. There are plenty of ways to use your ingenuity here! Your junkbox is your friend!

- Then I co-aligned the camera to the mount's RA axis. To do that, I used the polar finder and Alt/Az adjusters to get Polaris on the cross-hair marks (not the circle). The
camera was aimed at Polaris, and I checked that Polaris was in the center of the frame, by making an exposure. I adjusted the ball mount until it was perfectly centered.

- The last step is to align the red-dot finder to Polaris, too. With that done, everything was co-aligned.

- Don't forget to re-adjust the polar alignment to the real North Celestial Pole (not the cross-hairs)!!!

- You could use any convenient target rather than Polaris, but it was easy to see, and required only a small shift of the RA.

I'm a rank newbie, too; so I hope I've got that right. Seems to have worked for me...

Here is an option. On Amazon 15.00.

SkyWatcher S20550 Star Adventurer Ball Head Adapter, Telescope Accessory, Black

You will probably need an adapter to change the 3/8 thread to 1/4 for your camera, or simply change out the 3/8 threaded post. Very simple, but you can not adjust the camera fore/aft, like a dovetail bar.

As I await delivery of my EXOS2 is there a quick & dirty method to mount my DSLR to it?  Will probably attach nothing more than a 135mm lens and try rough PA with the included polar finder.

Re: EXOS 2 GT Payload Capacity

Mark Christensen
 

Jeff,

One thing that is biting you, I am sure, is the focal length of the 8 inch SCT. That is 2000mm compared to (assuming your APO is f/7) 570mm for your APO. That means the imaging results are nearly 4 times more sensitive to the mounts capabilities, irrespective of weight, which I kind of doubt is the issue.  It also means your exposures, because the SCT is an f/10, have to be twice as long, increasing the window of time in which you are vulnerable to problems in the system, atmosphere, you name it.

So I wouldn't just blame the weight capacity of the mount. 2000mm focal length is pushing it for a mount of this class. Some people make it work but most end up frustrated.
It's why people buy things like the Losmandy G11.

Hope you've been imaging the comet with camera lenses and your APO. With a short focal length telephoto with a fast lens all you need is a tripod, even something as short as 85 or 135mm focal length can produce nice pictures of it. And the speed of that type of lens (f/1.4 to f/2.8 typically) make for short exposures.

With the 8 inch SCT all you'll get is the nucleus.

Sincerely,

Mark Christensen

Dave,

That is positively inspiring! I have a long long way to go, and after last night's session with a cheap kit lens on my DSLR shooting NEOWISE I was about ready to resign myself to astrophotographic obscurity. But I have some capable equipment (iEXOS 100, AT72EDII, Nikon D7500), so seeing your image tells me I need to keep expanding my horizons and learning to use the tools. Thanks for sharing! 

Jim

Thanks man.  Zoomed in a bit more ....sooo many stars..(as Brian Cox would say), I def' feel a starnet routine on this one!....  Mount is behaving excellently . consistent over 170mins

This mount works.  Period!

You have to have the location of your site set both in the Es ascom driver and in stellarium.  You also have to make sure the time is set in your computer and the stellarium time is “now”.

Also remember in stellarium the longitude is “west” and in ascom driver it is -  ( negative)

Never mind, just found it in Stellarium.  The location must be off, as I tried slewing to the sun and it’s pointing towards the ground almost 180 deg opposite to where the sun is...

So select an object on stellarium and press , I think, the control key at the same time a the number 1.    The mount will slew I think.

I had not. Now that I have  I see it is “connected”👍🏽

At this point how do I invoke the slew function  - is it from within Stellarium or from Poth hub ?
