Post a picture of your Assisted Visual Setup.
Posted 11 November 2013 - 07:16 PM
And maybe someone wanted to see the setup and monitor a little better… though the shot was taken 15ft away, with flash, using a *BLEEP* point and shoot camera. The image on the monitor was really nice.
I forgot to mention in the prior post, this Jr Pro has the EXView upgrade chip (I have never seen a Jr Pro with the standard chip so i cannot compare or comment on that front).
(yikes! all the dust on the forks show how long its been since its been worth setting up in the backyard).
I want to extend a big thank you to everybody for advancing video assisted astronomy. It has brought REAL astronomy to my backyard.
Back to lurking...

Nice set up enjoy it. Video astronomy is a great way to observer.

nice setup! The 7" Marshall monitor is a 16:9 panel?!
The video out of the Mallincam is 4:3, so do you
use full screen?

I bought this monitor before i bought my Jr. Pro and compared it side-by-side against a Speco and it really blew the Speco away (i thought it would be the other way around).
I think this monitor is the same as the Lilliput equivalent though there are many different models available. Main thing i think is to get a resolution that is higher than VGA - some of these little monitors are 320x240 resolution which would be sub-optimal.
Hope this helps. I'm no expert but got lucky with this setup.
Why have people stopped posting pictures of their setups?

Wow, that is cooooool!
Thanks for showing us.

My 10" Meadelestron setup with the new Lodestar X2C on the "Above-the-Roofs Deck".
(You cannot be above the top of the evergreens in the Evergreen City.)
Here is a closeup. The camera sticks out because it is attached to a x0.5 focal reduce on a 1.25" nosepiece and spacers. Another x0.63 focal reducer is attached to the nosepiece of the Vixen flip diagonal inside of the Meade zero image-shift electronic focuser.
Notice the single wire USB connection. No more power cord + computer control cable + composite video cable + S-video cable with the fully digital camera. (The bent conduit on the right side of the first photo used to keep the multiple wires of the old setup from entangling, while the telescope rotated. Daytime it also serves as a squirrel-proof bird feeder holder 25" above the yard.)

Do you get much vibration from being on that roof deck? Neat idea... Is it accessible via the attic?
Posted 15 September 2014 - 05:11 PM
The access is through an external wooden staircase that also served as a fire escape for the four lower living levels of the house. (The fire department no longer requires this.)
There is certainly vibration, when someone moves around on the deck. One has to sit quiet. Yesterday a friend came over after finishing her evening shift at midnight. When she started to climb the stairs on the ground level, I saved my last sub and turned off stacking. Then, after we sat down and she got her champagne poured, we could resume observing. There is not much traffic around here that would shake the building. If someone walks around on the lower floors inside of the building, that doesn't harm the experience on the deck.
I am sure that this setup would not suit astrophotography purists. But for visual and electronically assisted observing it is great. You also feel closer to the sky once you are above the neighboring houses...

These are my two electronicaly assisted setups (vintage scopes!) On the left orange Celestron 8 with diagonal mirror + 0.5x compressor lens, rignt 1983 Vixen refractor (80mm f/11.4) + 0.5x compressor lens. My camera is the LN300 cctv with C to 1.25" adapter. I use either my laptop equipped with a frame grabber or my old 14" crt tv as viewing monitor. Sorry for the cellphone low quality pics

Very nice Giorgos. It's great to see that pair of classic scopes still getting good use.

Thank you for your kind comments Mark! If I had to keep just two telescopes they would be these two!

Here's my current AV rig..
I'm wishing for a few nights without clouds for Christmas..
So far, the long range forecast is looking pretty good for April... Hey! That's for 2018.!.

My widefield Lodestar setup
with Nikkor 180mm f2.8 lens and filter drawer on a ZEQ25 mount.
Here is a clearer close-up on the kitchen counter.
Finally all parts taken apart.
I list the parts from left to right.
1. Tripod attachment ring (from ebay) bolted to a 4" dovetail.
2. Nikon lens to M42 adapter (from ebay).
3. Teleskop Service filter drawer with T2 threads (with drawer halfway pulled out).
4. 15mm T2 spacer.
5. Teleskop Service camera rotator.
6. Teleskop Service 1.25" eyepiece holder with T2 threads.
7. Lodestar x2c with 1.25" parfocalizing ring attached (the yellow plastic ring is just decoration).
The 15mm spacer and the camera rotator are not essential. The round Lodestar can easily be rotated in the ep holder and with a parfocalizing ring it would not get out of focus. But since I had the rotator, I am using it. Also I feel more comfortable with the ep holder gripping the camera in its middle rather than at its end.
For the Pentax lenses I just use a "Pentax M42 lens to Nikon adapter" (from ebay) added to the front of the setup on the photo.
To illustrate the field of view achievable with the various lenses from 35mm to 300mm focal lengths, I collected captures of a few winter nebulae here. http://stargazerslou...r/26379-dom543/. They are sorted in the order of increasing FOV.

Very nice! I like the TS filter drawer. Might have to pick one up. I've been using my Tamron 300mm F/2.8 a lot with my night vision stuff. Both the relay lens with my dslr and with eyepieces for live stuff. Tamron has regular 2" back with brass compression ring for astronomy. Bought it modified, but have another 300mm Tokina I could use a filter drawer on and would be cool. The wide views are awesome. Have a 135mm F/2.8 I like a lot too.
Posted 12 April 2015 - 12:44 PM
Nice setup, Dom.
Using camera lenses for wide field EAA is a great idea. I had some old Nikon lenses that I adapted to my Lodestar with an inexpensive Nikon to C mount adapter you can get on eBay. Don't have a filter drawer, but I glued an empty filter ring inside the adapter so I can screw in a NB Ha filter. I use a finder scope tube to mount the setup to my main scope. The wide field views are great.
Here's the setup with a Nikkor 105mm.

Great idea to mount the camera lens setup in a finderscope tube and bracket. Especially for the smaller lenses, which don't have much space to accept a tripod attachment ring.
The US source for TS parts is OPT. They have also got me parts from TS that they didn't have in stock. The filter drawer comes in two varieties: With M48 or with T2 therads on the external housing. As for extra drawers, it makes sense to order the 1.25" ones. They are, actually, the same as the 2" drawers but with an extra 2" to 1.25" reducer ring included in the same price.
Other makers of filter drawers are Starizona and Hutech-Borg. The Hutech one fits the M57 based Borg system but the only source for adapters is Hutech. On the other hand, it can also accommodate 52mm filters.
Here is the same setup with a bigger boy.

I just purchased a Mallincam Extreme, and par for the course, weather has only allowed 2 outings with this camera... the first outing was night time via an 80mm triplet and with marginal results... until after the next outing did i realise that I had a pretty goofy default histogram setting... the second outing did a litle better as it was via my Lunt and therefore a bit of solar playing...
On this post, I see a number of folks using their diagonal with their camera on their SCT... is the diagonal needed ?
Posted 12 May 2015 - 01:12 PM
I used my diagonal the other day.. I broke the mount for my red-dot and had to repair it.
So, when I re-installed it, I wanted to line up with the star-finder scope..
But, just to be safe, I alined both star finders, using a 6mm eyepiece.
I think you might need a diagonal, if your camera was too long and might
come into contact with the mount.. Otherwise, it's not needed.
