I have a 114EQ-DH4 and want to use it with my DSLR
Posted 16 October 2012 - 07:32 PM
I've been trying to figure out what accessories I need to be able to take pictures with my Nikon D90 and my mother-in-law's 114EQ-DH4. So far all I've been able to gather is that the 114EQ uses a .965" eyepiece which will not work with the universal 1.25" T-adapters and rings. But one review I saw for a .965" T-adapter said that your pictures will come out with bad vignetting around the edges. Is that true?
I've also been unable to determine if I will need an additional Barlow lens or if I can use the 3x Barlow that came with the 114EQ. It seems there may be an issue with being able to focus my camera due to the shorter focal length. Basically,all my research is leading to me to more questions and no answers. Anyone else use a DSLR with one of these older telescopes?
Thanks for any help.

I do not do imaging, but have an idea. Get a lens holder for the scope that uses 1 1/4 inch eyepieces. The one place I know that has something is Telescope-Warehouse.com. Other places have adapters, but this company knows about what fits older models. I would call Bill Vorce, the owner, or email him with your model number. I think his email address is scopehed@ frontiernet.net, but look it up on his website. There may also be listings on eBay for such an adapter, but I think contacting him will help you get the right thing the first time.
I believe he has one that is actually for 2 inch eyepieces with a 1 1/4 inch adapter for it. You can then get the appropriate T adapter rig for your camera. Regular telescope or camera stores, either real ones you walk into, or on-line stores will more likely have the particular adapter for your camera. However, Telescope-Warehouse may have the part that goes onto the telescope itself.
There are several other sites on eBay that sell such things as what you need, but Telescope-Warehouse is the one that comes to my mind as most likely having your particulars.
Hope this helps,
Using the basic setup will work the same as a 900 mm lens on your camera. Using a barlow lens will give you additional magnification as needed. With higher magnification, longer exposures will be needed.

I did finally manage to find an eBay seller who carried the 0.965 camera adapters and T-ring mounts. Hopefully those will work out and I can start snapping some shots. If it doesn't, I'll certainly give your guy a message.

I acquired this same scope a couple of months back. Didn't take much to get it in perfect working order. However, I was very disappointed that the instructions didn't explain the setup better. Every other EQ I've ever seen has a home position starting horizontal. This one starts vertical. No where in the instructions did I see this mentioned. Took me three nights to get it figured out. And the GoTo is a bit iffy as far as acurracy goes. But it has a nice perimeter slew to help you locate the object.
I ordered the 1.25 focuser back and I replaced the chromed plastic focuser tube with a black anodized metal one. New battery pack. New eyepieces. New spreader and accessory tray. And I had to replace the focuser knob. The existing one was bent. I still need to put a collimation circle on the primary mirror. And I need a better way to align this to true North so it tracks more accurately.
Now that I have it working again, I was also curious about photography. My biggest concern would be focuser flex. A DSLR is quite a bit of weight to add to this thing. I guess I could invest in a cheap optical camera like the old Meade LPI USB cameras.
What are your thoughts?

Whatever camera you would use on a scope like that would need to be fairly light. What few attempts I have tried with a regular camera ended up being a failure so far, except holding my little digital camera up to the eyepiece on my Eclipse 114, table top "Dobsonian" during the solar eclipse. There are some brackets out there that allow you to put some models of cell phones up to an eyepiece as well. You might try holding your DSLR up to the eyepiece for starters and see what you get. Phillip Pugh does that kind of thing all the time and put all sorts of pictures he took that way in his book on the Messier objects to show what someone can do.

I would say to stay with something like the Meade LPI, or DSI to keep the weight down. A DSLR is heavy. I also don't know if back focus would be an issue with that scope and a DSLR.
