Subject: D-70 Sent: Thursday, September 24, 2009 12:43:55 From: Mike Quinn (firstname.lastname@example.org) It's been a long time since I sent you a question or comment, probably since 04. I was looking at your deep sky pics and saw that you had some done with a D-70 on a 125. How on earth, due to weight, did you mount a 70 on a 125? I have both and would like to try it now that I am getting back into using my scopes/cameras. Do you by chance have a picture of the 70 mounted to the 125? Any help would be greatly appreciated. Thanks, Mike Quinn Manistee, MI (formerly San Diego, CA)Mike here: I don't think I've posted a photo of the Nikon D70 DSLR mounted on the ETX-125. I have posted on of it piggyback on my ETX-90RA. I've not any weight issue with the D70 on the ETX125, although I did when it was attached at prime focus on the ETX-70. For most purposes on my ETX-90/105/125 and LX200, the D70 is mounted in the normal eyepiece hole using a 1.25" adapter and T-Mount. No weight issues for me.

Subject: Etx-80 & nikon D80 Sent: Wednesday, July 22, 2009 10:01:52 From: Robert G von Giebel (firstname.lastname@example.org) In addition to the night sky, I use combined devices to photograph wildlife. That is I photographed wildlife with an ETX-60 with no problems. I have gone thru a two(2) year saga with Meade where the electrical aspect did not work & they upgraded with a defective ETX-80 & it's replacement was equally defective. I now have a working unit except I'm unable to take any photo's. No matter what the setting all I get is white snow. I get a view thru camera viewer but that's it! Meade referred me here as Nikon couldn't/wouldn't help because Nikon didn't make telescope. I'm using correct adapter & T-ring. The telescope focal length is 400mm & recommends f4.4 as photo speed. Nikon doesn't have this focal ratio as a setting but has 4.2 & 4.5. Any suggestions would be greatly appreciated. Thanks in advance. Frustrated :( Atch'd are wat I get with subject devices. Meade referred me to your site. Would appreciate any suggestions. Manual recommends f4.4. Nikon only has f4.2 & f4.5 but get same results. Thanks I AM, Robert G von Giebel
Yes can see & focus thru telescope. can also see thru camera viewer. Will not function in auto mode.Mike here: Try setting the M/A switch to M to turn off AutoFocusing.
Pixs I took origi& sent to you were "M" setting. I've also updated firmware & reset camera settings.Mike here: OK. The AutoFocus was off. I take it you used the fully Manual exposure mode. What was the object, time of day, and exposure settings (f/stop, shutter, ISO)? [Oops, "f/stop" should not have been in the list since you don't have a lens attached to the camera.]
Subject: Need help Sent: Tuesday, June 2, 2009 09:15:14 From: C. S. Broward (email@example.com) I was looking at your web page and noted that you were using a D-70 with a barlow. I have had no luck doing this---I end up with a hotspot instead of a image! Can you tell me how you have your system configured... thanks Chuck in N. Florida -- Chuck Broward GhastlySky Observatory Gainesville, FloridaMike here: First, please see the Email Etiquette item on my ETX Site home page; your message was originally marked as SPAM due to the ambiguous subject. Thanks for understanding.
Thanks for responding so quickly... I use my D-80 at prime focus with a 1.25 inch adapter. This focuses fine with my C-8, Vixen 102, MAK, etc... Placing the barlow in the scope focuser, and then the camera into the barlow (2 x shorty) produces the hotspot effect... I have not tried extension tubes etc. Some of my attempts at astrophoto: http://picasaweb.google.com/GatorChuck/Astrophotos# Any input would be greatly appreciated....I would love to get a bigger planetary and luna image on the camera detector! BTW, I have followed your ETX Site for years...it was one of my first storebought scopes.... Clear Sky ChuckMike here: I haven't experienced that. See if you can determine where the image focuses with the Barlow Lens. Use a piece of tracing paper and focus the image on the moon. Then see if the distance is close to where the camera's focal plane is. That way, you can at least determine whether an extension tube would help.
I'll give it a try tonight....I'll let you know what happens. chuck
Subject: Nikon DSLR Time exposure Sent: Wednesday, March 18, 2009 09:09:02 From: Allen Pinkall (PinkallA@hutchcc.edu) My Nikon D50 has a limit of about 15 minutes for time exposures. I suppose the purpose of this is to save the batteries from going dead. Is there a way to over-ride this limit? If I would purchase an A.C. adapter would the camera automatically allow longer exposures? Thanks for any help, AllenMike here: My D70 has a limit of 30 minutes, regardless of whether using the battery or AC. So I suspect it is a limitation of the sensor or other electronics.
Subject: not able to focus Sent: Sunday, February 8, 2009 01:10:11 From: Don Morris (firstname.lastname@example.org) I attached my D80 Nikon to my etx 90 and was not able to reach focus I used a Meade two piece tube and T mountMike here: I never tried using the "Meade Camera Adapter" with my Nikon D70, although I did use it with my Pentax Spotmatic SLR years ago. The ETX would focus with the Spotmatic. Have you tried using just one piece of the camera adapter (it separates into two pieces)? I use the "OPT Camera Adapter" (see the Accessory Reviews: Astrophotography page) with my D70 and ETX and LX200 telescopes.
Subject: Nikon D80/Scopetronix Maxview/ETX-125 setup Sent: Monday, February 2, 2009 16:13:59 From: Mike Pilgrim (email@example.com) I'm sure that in all your pages on astrophotography using your DSLR I have seen at least partial answers to my question of today. Unfortunately, I don't recall seeing my exact answer. So here goes. To go with my new Nikon D80 and ETX-125AT I received today the Scopetronix Maxview DSLR adapter and accompanying T-ring. Except for no indication where the included 1.5" rubber O-ring is employed, the written user instructions from Scopetronix seem quite complete. Within those instructions however is the disclaimer regarding the total weight of this configuration when coupled with the Nikon DSLR, related to the possible need for proper counter weights on the scope to help neutralize the gear stress. I recall your D70 is used with your ETX-90 and different tripod (mine is the 884 Field model), and I don't recall any mention of counter weights in your experience. I wonder if you or any of your viewers know of or have a configuration similar to what I am creating, and if so, I'd like to hear of any counter weight issues and suggestions on how they were solved. I hope to use my setup with the scope in Polar alignment mode (which obviously positions the D80 mounted in the main eyepiece at a balance point different than if using AZ/ALT mode). Should I employ a counter balance system, and if so, where is a reference to understand where to obtain and how to employ that concept? By the way, I have on order a piggyback camera mounting strap (with counter weight) in case I wish to use the D80 riding on top of the OTI. Might that strap and weight be simply strapped around the OTI in a position which can help offset the weight of my eyepiece mounted gear? Looks like a cold front is moving in, so I apparently have a couple evenings to study this situation and try to figure out what I need before the next clear sky night. Thanks, Mike Pilgrim Boca Raton, FlMike here: I haven't had any problems with my ETX-125 on the #884 tripod and the D70. I didn't use my Maxview II (before it was stolen, along with the LXD75-8"SC) on my ETX telescopes since it was a 2" device. As to counterweights, yes, the can come in handy. Scopetronix (in the good old days) had a piggyback adapter that doubled as a counterweight; the weight was threaded for the camera mounting screw. You could probably do something like that.
