The busy area around Sadr

[gorann]

This is what my wide-field Samyang 135 captured while piggy backing on my dual-RASA8 rig aiming at Barnard 343 (the RASA image posted here yesterday).

Apart from many well-known objects, including the Crescent Nebula, I like the 3D feeling given by the ringed tube-like red nebulosity extending towards the center from the lower left. I have added about 50% RASA data to some parts of the image. Even if the moon was at 75% (but close to the horizon) my Bortle 2-3 sky may have helped while I was shooting between the clouds.

Material and Methods:  Samyang 135mm (@f/2) with an Omegon veTEC571C and IDAS NBZ dual-band filter (Ha+Oiii). 39 x 5 minutes, so just over 3 hours. Processed in PI and PS, including StarXTerminator.

Cheers, Göran

Very nice, great colour in the Crescent Nebula for such a short integration time. I didn't know you had gone down the 'budget' IMX571 camera route, but presumably not purchased direct from China?

Thanks Steve! Well I also have three ASI2600MC, but when I realized I needed one more (at least) I took the chance on the Omegon variant. Great thing with it is that you can buy it from European dealers and with a warranty (Omegon is a brand owned by Astroshop.eu but this camera is made by Touptek but in a Omegon designed casing). Mine has worked just fine so far after I started running it from NINA. It even has a anti-dew heater (at least there is a function in NINA that allows me to turn a heater on and off so I guess it is there). No fog issues so far.

Very nice Göran, it looks like an old master in some ways.

Thanks a lot Ian! I see what you mean and agree - I sometimes get this feeling about some astro images.

This is a fantastic image with the soap bubble clearly defined. And lots of other detail as well.

Thanks for posting Göran. Lots of fine detail shown even in areas which don't have a designation. And plenty of colour too. 😊

Thanks so much Wim and Alan, much appreciated! And needed after two weeks of clouds, and apparently at least one more cloudy week coming up....

According to Clear Outside, we're supposed to have it clear outside on friday. During the day. 😒

Very nice indeed and so much more efficient than multi-panel mosaics for catching large objects with little localized detail.
