I've played around with the colours a bit more, to try and give it a bit more "pop". I wonder if it has gone a bit too far? Thanks for looking. https://astrob.in/w69q1x/C/

Thanks Scotty!

I've got a Pegasus Indigo FW and it is very good. It aligns the filters perfectly. No light leaks on mine.

I was able to capture 2hrs 55' of OIII last night and added it to my Ha data for a bicolour HOO image. More info on Astrobin: https://astrob.in/w69q1x/B/ Thanks for looking! P.

A quick 2hrs 35' on the Crescent Nebula from my backyard in East London (bortle 8-9). Seeing was unusually good for London. Hopefully the weather will cooperate so I can add OIII. Astro-Physics 130GTX w/ FF, Mach2GTO (unguided 5min exposures), Poseidon-M Pro camera, Chroma 3nm Ha filter. More info on Astrobin. Thanks for looking! Best, P. https://astrob.in/w69q1x/0/

I don't have one myself but have heard about this issue and how to fix it here:

Or you could get a 2.7nm filter (it's +0.5nm/-0.1nm). There must also be an undisclosed margin of error for the 3nm pros. In any case, the filter bandpass is not the only interesting metric. The fact that it transmits more Ha, OIII, SII - which is what we're interested in as imagers - shouldn't be overlooked. In the worst case scenario, a 3.3nm filter bandpass isn't so bad...

Comparing the spectrum curve charts, the 2.8nm filters transmit more light in Ha, SII and OIII. This is reflected in the higher price. It's a better filter than the 3nm, so if price is not an issue, I'd go for the 2.8nm instead.

It would have to be my AP130GTX. 😍

Hi Leti, I use Chroma and Astrodon but have used Antlia before and found them to be quite good for the price. I've also heard good things about the new Astronomik MaxFR range, but have no experience with them. Typically, the narrower the bandpass the better in light polluted skies. For Bortle 6, I'd go for the Antlia 3nm / 4.5nm or the Astronomik 6nm. You'll want to get matching LRGB filters of the same width to avoid problems.

That's the diameter of the lit panel. The edge around it adds another 2cm.

I got them straight from Xiaoming Li at Startrip. His email is the first listed in Wanderer's website's contact page. edit: I'll add that they arrived quickly and well packaged.

I have a 125mm and a 190mm Wanderer Cover Mini 3 and they work really well. I connect them via usb to my Pegasus powerbox and automate my flats using NINA. A big difference between the DSD and the Wanderer is that the latter only needs usb power.

If you think you may go full-frame in the future, I'd get 50mm unmounted filters and skip 2" altogether. If you're happy with sticking to APS-C, then 36mm unmounted is what you'll need. Antlia is fantastic value for money and better than optolong, if you can stretch your budget a little bit. Whatever you decide, stick to the same filter width!

To fix this, I've had to check a box to reverse the rotation. You can do it either in NINA or in the Unity software. Don't ask me why it works, but it works.

This is very cool and appealing to me and I am following with interest. If only they added software sky modelling, the FireANT would be the perfect portable mount. I find that modelling really makes absolute encoder mounts shine, and can easily notice the difference it makes on my A-P Mach2GTO.

I quite like the combination of Clear Outside, Meteoblue (astronomy), and Windy (meteogram and cloud cover). They rarely agree, but when they do, it’s a good bet it will be clear out. P.

I haven't purchased their rotator, but I did buy their WandererCover V3 Mini (motorised flat panel). They put a good video tutorial on how it works on youtube so I thought why not give it a try. Quality is good and the CEO (Frank [removed word]) responds quickly to emails. It arrived quickly but there was an issue with updating the firmware. I wrote to Frank and, in one day a new firmware was available online and the device has worked flawlessly since. I do have the Pegasus Falcon Rotator which I love... In any case, WandererAstro have a webpage in English with more details.

Thanks for the kind words. I hope to add OIII and SII after I'm able to dial in backfocus/tilt.

This was second light for my setup. Humidity in the high 90%s and maybe I shouldn't have been imaging, but this was only the second clear night this year so I went for it. Backspacing and tilt still need to be addressed. Taken with the CFF92 f/6 + Riccardi 0.75x flattener/reducer on the Astro-Physics Mach2GTO-L running unguided 300s exposures with the Chroma 3nm Ha filter in my Bortle 8/9 backyard in East London. Cheers, Pedro .

Dear all, my first image posted in these forums and my first astrophoto since 2009. A quick test of my setup, taken with the CFF92mm F/6 telescope + 0.75x Riccardi Reducer/Flattener and an Astro-Physics Mach2GTO. These were 300s unguided exposures through a Chroma 3nm Ha filter in my Bortle 8/9 backyard in East London. Thanks for looking. Cheers, Pedro

I'd go with the recommended TS Flat 2,5 or the identical Sharpstar 2.5" version. You may be able to find one of these used. The thing to keep in mind with those two is that the threads on the camera side are actually M69, while threads on the telescope side are M68.

On the topic of AP customer service in the UK, I have been very happy so far. One of the Eagle tripod feet for my Mach2 arrived damaged. AP promptly sent a replacement to me via Michael from Baader. Both companies have always been a pleasure to deal with. Whilst I suspect an issue with my Mach2 would be more troublesome to deal with (if shipping back to the US for repair was required), I’m sure in the end I would get the same customer satisfaction, with perhaps slightly longer transit times.

Looks good Mark! Are you satisfied with the 6nm ha filter in London or wish you had gone 3nm? I ask because I'm trying to decide between the two and live nearby!
