Planetary Nebula - The Helix (NGC 7293)

Nice "Eye of God", to what i know, this object is of "Very High Degree" of difficulty due to its very low surface brightness caused by relatively large surface area, hence i strongly think that you had taken this outside Singapore Sky, probably at Sedili, Punggai or even further ??? Otherwise, how come yours so nice & mine so not nice ???

Peter,

Shooting DSO from light polluted sky in Singapore is very difficult when you use a DLSR (full color sensor).
The foreground sky is brighter than the background.
The image hence contain more undesirable foreground light than the background objects.
It inherently manifest as noise and color cast which is very difficult to get rid off.

A LPR filter can helps a little but it will shift the natural color of the object.

Narrowband imaging perhaps can give you better result, but then we would be involving fast scopes which are rather expensive and not easy to handle.
NB filters are also terribly costly.

The most practical way is to go to a darker sky area in Johor to do AP.

Very good image! May we ask, whereabouts in Johor was the image obtained?

[beginner]

Sedili.

Belated greetings, beginner! Beautiful image!
Can I confirm that dot in the middle is actually the progenitor and not some foreground/background star ?

Airconvent,

Thank for your nice comment.
The centre star is so central that it does appear to be the progenitor star.

Peter, a DSLR with H-alpha filter works in sg.

Here is proof. 450D uncooled. 2x5min

Hi Jeremy, nice Ha Helix, pin sharp stars, what scope & mount used ? The polar alignment slightly out, lol, can give me ur contact 1 more time, lost it, sorry ..
