Here is my current setup:

 

gallery_280529_10252_35488.jpg

 

Scope: Meade Mini LightBridge 114mm F4 newt,  modified with non-rotating helical focuser

Camera: RisingCam IMX290 mono (0.71°x 0.4° FOV, 1.33"/px)

Finder Cam RisingCam IMX224 with 25mm f.l. F1.4  IR CCTV lens (11.2°x 8.4° FOV, 31"/px)

Mount: Flea market Vixen Super Polaris converted to GoTo with OnStep

 

Batteries for field use: a pair of 4000mAh 3 cell Lipos from my RC hobby

 

Scope PC: BeeLink S1, running SharpCap, RishingSky, and Cartes Du Ceil

Wifi Router:  gl.inet ar300m with a high gain antenna

 

Control PC: Chuwi h10 Windows 10 tablet, or home PC with RDP

 

 

I've put this setup together over the past year and a half. It has been really fun to use. The small fast scope paired with a small low noise sensor, makes for an easy setup with a forgiving pixel scale and a utilitarian FOV.

 

The RDP over dedicated wifi has been very liberating. No more wires tying the tablet to the scope, I can drive it from 100ft away in a car/tent, or I can seamlessly transition to using my indoor home desktop.

 

For remote operations I love having the second wide field finder camera. It is really handy for avoiding roofs, trees, and clouds, It also allows me the star hop if I want to. 

 

For the cameras, I'm using braided jacket USB cables. These have been great, they don't get stiff in the winter, and they hang and flow smoothly so they don't snag on things as much as the crinkly thick PVC cables. Highly recommended. 

 

Eventually I will mount the PC and batteries to the tripod leg and tidy the cables, but for now,  I'm having too much fun with it to bother.

One quick question I have, before reviewing the details of your setup, is which helical focuser do you have? I have a 1986 Celestron Comet Catcher with a funky focusing mechanism. If you look at post 763 of this topic, you’ll see the same scope and where another CNer converted the focuser to a helical one. I did the same but the focuser I have, Svbony, has some internal play so the camera can shift slightly off the optical axis when I focus it. This causes focus and collimation instability so I’m interested in trying another helical focuser. 

Thanks for you input!

Gary

I am using the cheap SVBony 1.25 Helical focuser. It has a very small amount of play, but I didn't notice any image or collimation shift. I'll check next time I'm out.

 

Maybe their quality, fit & finish is variable. 

I'm also using a 1/3" sensor which is very tolerant to tip/tilt  since it is small.

Could it be the comet catcher's sled that has play in it?

 

I'm using the $23 focuser, they also make a ~$50 one that has more travel. Maybe it is also higher quality.

For size reference, below front and center is my NVD Micro Image Intensifier.

 

The eyepieces to the left are TV Delites and to the right at TV Radians with old Mead 24mm and 40mm wide field eyepieces in the back. The intensifier is used in my 102mm F5 achromatic refractor, Tak TSA 120 refractor, a Mewlon 210 and also in a repurposed 50mm guide scope (photo below) for handheld low power observing. The complete N American and Pelican Nebulas easily fit in the field of the guide scope with room to spare. 

 

Except for a few comparison looks between glass eyepieces and the intensifier, I haven’t used a glass eyepiece for deep sky observing since I got the Micro a of couple years ago.

Hi

The Comet Catcher sled is locked down. I can see and feel the play in the SvBony focuser. The ASI 294 camera has a large sensor so perhaps is more impacted by wiggle in the optics. 

Thank you

Gary

Here's my star party set up for EAA and some visual.  The CPC 1100 for small deep sky stuff and the refractor for wider shots.

Star Party Equipment Setup scopes
 
Here's a view (with labels) of my old control room with a kitchen.

I just picked up this blacked out portable shelter but I have yet to get it out under the stars.  Hopefully I'll get lots of good use out of it at ECVAR in September and SRSP in October.  The kitchen will not be inside this shelter.

Here's a video on I took of the shelter set up in my living room:

 

The main reasons for getting rid of the 10'x10' popup canopy were the set up/tear down times - 20 mins each - and I had to take it down if the wind got over 20mph.  These portable 5 hub shelters are completely black out - no light leaks, rain proof and are built to stand up to strong winds.  This shelter is designed to be set up on a frozen lake for ice-fishing.

Hello new adventure on Eaa for me and for French community.

 

i'm going to try the night vision with two P8079Hp 

The first one is ready to every télescope in 1,25"barrel.

Here on 130/650 pds starblast rocker.

Here are some pics of my rig. 

 

It started out as an old 1960s research grade mount that weighed 600lbs (counting the pedestal).  It is a nice well thought out design.  The manufacturing was very high quality.  It has dual axis worm drives and slip clutches.  The drives were powered by 60Hz 1 rpm synchronous gear motors.  Here I am unloading it,  Pics of some of the internals are in this thread  https://www.cloudyni...-mountpedestal/.

I bought a 16" Sky Watcher collapsible dob and built a makeshift cradle out of 2x10s. I then modified an old 3pt bail carrier to serve as a movable platform.   At this point I could move it around on the back of a tractor.  This worked, but polar alignment was a pain.

This is my setup.

Celestorn edge hd 8

Celestron cgemii eq mount

homade base for the tripod

zwo asi 294 mc pro

Hp laptop with New tight nc connection installed on my laptop and main dell pc so I can remotly control my laptop and mount inside my house over wifi.

I just received the camera and its been cloudy. I have not had a chance to use it yet except during the day at a tower.

I cobbled together a basic ST4 autoguiding controller using old variable frequency drive correctors and relays.    This was better, but I still had to position the scope manually (although I could make centering adjustments via the ST4 drive).  So I made a controller based on a 3D printer board and Howard Dutton's  ONSTEP code.  This gave me wifi, goto, periodic error correction, and the ability to operate it remotely from my computer.

I also put wheels on it so that I could roll it in and out of the hanger.  And I added trailer jacks which allowed me to efficiently polar align it using Sharpcap.  When the rear is up on the jack, the 4 wheeled buggy becomes a 3 legged tripod.

After adding additional piggy back scopes, complete with remote focusing, here it is in its current form.  Oh, and I upgraded the front wheels!

 

The current scope lineup is:

16in Newt with ASI183MM Pro.

6in Newt with Canon T3 (modded) and GSO coma corrector.

Televue Pronto with Canon T3 and 0.5x focal reducer (spaced for 0.7X).

50mm finder scope with ASI290MM mini and 0.5X focal reducer (spaced for 0.8X).
