I shot three frames at ISO 800, 2 minute exposure in ambient-ish First two are no LENR, third frame is LENR Not tried calibrating yet with darks, I think I'll have to shoot 12 frames and stack, ...

Cheers, I see what you mean. If I get time next trip out, I'll try with and without LNER as I usually have a few hours to kill whilst the SXD2 does its thing :)

Appreciate the feedback but darks are a waste of time out here with the temperature drift, both ambient and on sensor. Impossible to get any meaningful correlation, which is why I'm thinking that ...

My main rig is a SXD2 EQ mount, AAP tracking, dithering and guiding, cooled OSC camera. I'm heading out into the desert end of the month and taking a second rig for Milky Way photography. This will ...

I use a D610 for full frame landscape Milky Way, untracked I use ISO 1600 - 3200 with a fast 20mm lens at 15 - 20s exposures f2.5. Exact settings depend on the histogram, avoid clipping to the ...

I changed the counterweight from a skywatcher star adventurer type to a vixen polarie type. I can mount a Gt71 on this and track up to 4 minutes unguided if accurately polar aligned. Great quick ...

Basically more integration. Also check exposure so you are not clipping either end, and shoot at the best ISO for your camera sensor. For my D5600 this is ISO200, but I'm underexposed on Pleiades ...

Photos, Orion 16 frames ISO400 3mins, WO Gt71 UNGUIDED, and counterbalance set up using s/h vixen counterweight etc.

Late to the party here but I'm on my third tracker and it's a Fornax LT2. Head and shoulders above the others I have had, both in terms of manufacturing quality and performance. To get the best out ...

So how did you get on with this?

I cobbled together a counter balance arm initially from my old Skywatcher SA and using a couple of flat pan heads, and then changed this to a Vixen counterbalance arm. Tracking is absolutely ...

Same question here ;) Also could I expect less coma on a cropped sensor given that it is using less of the image circle?

Thanks! I will look forward to seeing some examples. Much appreciated

The Astrobin photos appear to have incorrect backfocus where artifacts are visible. The artifacts appear to be inward radial coma indicative of the camera sensor being too close. This is amplified ...

Bookmarked as I need to check this on mine

I've owned both the Skywatcher SA 2 and the Fornax LT2, and here is my considered opinion on the Fornax LT2: Firstly, it is well made and capable of tracking very accurately. Much more so that the ...

This is what i ended up with Telescope Express pano head with TE vixen clamp Star Adventurer counterbalance And a small rig rose jointed clamp to hold the arm on target when I reset the Fornax ...
