I imaged this object myself last year and my effort pales next to your image. Especially the outer ha nebulosity is ultra faint. Hats off! It's a superb shot! Pieter

Martin, It looks fantastic! Good to see you are liking your asi-1600! Best regards, Pieter

Thanks all for taking the time to look and comment! The Berlebach Planet is made from Ash wood and extremely stable, it can carry 120 kg without breaking a sweat. Been very happy with it. Pieter

Hello all, Last week I collected some o3 data from Southern France during my annual astro imaging field trip with 2 other imaging friends. The o3 shell in WR134 is very faint and could use even more exposure time. The HA data was made from my badly light polluted home locating in Belgium. I included a pic of my setup I drove 1000 km to get there. Equipment: Homebuilt 10" f/3.8 Astrograph with Wynne corrector Mount: Mesu 200 Sensor: ASI-1600MM-cool cmos -10°C Exposure: 14 hrs (5 min subs); unity gain setting Filters: Astrodon 5 nm H-alpha / Baader 4,5nm OIII 7 hours for each channel. Channels assembled as HA:O3:O3 Thanks for checking it out, Best regards, Pieter

Very nice! There is no o3 component in the planetary nebula? Only h-alfa? Regards, Pieter

Looks amazing and has your signature touch! (as usual off course ) Pieter

Thanks! I have it set at the unity Gain setting. Seems to work well for me, never tried any other settings. Thanks! I like the filter very much, I had a Baader 8,5nm o3 in the past and this one is a huge improvement. I still need to do some more testing, but I have seen some halos around very bright stars. A fault that plagued their old o3 filter. Pieter

Hello all, It's been kind of slow on the imaging front the last year; however during the last 2 weeks I gathered some data on the Pickering's triangle. It's a 2 pane mosaic; totaling 16 hrs of exposure time. It is my first bi-colour image, so go easy... I made some 100% crops that show some interesting details. No major post processing, just levels and curves and combining the channels. Equipment: Homebuilt 10" f/3.8 Astrograph with Wynne corrector Sensor: ASI-1600MM-cool cmos -10°C Exposure: 16 hrs (5 min subs) Filters: Astrodon 5 nm H-alpha / Baader 4,5nm OIII Channels assembled as HA:O3:O3 Thanks for checking it out, Regards, Pieter

Hi all, Some feedback on the Baader 4,5 nm O3 filter; I like it a lot! It is a very nice match to my Astrodon 5nm h-alpha filter. The stars are very similar in shape and size, which will allow me to make some nice bi-colour images. If I may give one small point of criticism; there are again some halos noticeable (remember the old 8,5nm O3 filter) around very bright stars. It could be something else in my imaging train, not 100% sure yet... But overall I am happy with this purchase. It will be a return for me to colour imaging after shooting b&w for a long time. Here is the first light; a quick and dirty bicolour on NGC7000. Scope was my 10" newton, exposure was 2 hours in HA and 2 hours in O3. Colours mixed as HA:O3:O3. Thanks, Regards, Pieter

Very nice, what kind of equipment was used? Pieter

Great capture! You captured some very delicate details. Pieter

This is a very cool picture, always interesting going for the ultra faint stuff! Pieter

This is a very nice image and object! Never seen it before... What is the image scale of your system ? Pieter

Hi Olly, Sounds like you owe me a beer for this great tip. ? I'll also go for it, I can tweak my imaging train to fit the 1,25" version in. Want to get into the faint planetary nebulae, guess I'll find out what it's worth pretty soon. Pieter

Triangular shaped stars are often caused by pinched optics. Is your primary mirror still properly supported? Pieter
