Bug, Ant and Box planetary nebulas et al

[John Hothersall]

SPX350 F9.1, ASI290 uncooled, Astronomik UHC+Baader RGB filters.

Seeing was variable for this lot but Scorpius Bug nebula came out very well. The Ant nebula in Norma Menzel 3 showed decent detail within considering the avg seeing.

The Box nebula ngc6309 in Oph has 2 bipolar components and IC2553 has a box like shape in Carina with bad seeing. The planetary in the Corvus square ngc4361 at 11th mag and 2 arc min diameter was very faint and needed lots of stretching, colour was barely visible.

The 12bit ASI290 is good at imaging high surface brightness/concentrated objects like planetaries but you cant beat a cooled 16bit camera for the faint stuff like the elusive halos.

Mars is ruined with dust storms so I am trawling the PN's in Sco/Sag/Oph with the ASI planetary cmos.

Regards, John.

A nice rendition of this set of planetaries

[Placidus (Mike and Trish)]

Most excellent work. We particularly like the resolution and clarity of the central dust lane in the Bug, and the extreme detail in the Ant.

[cometcatcher (Kevin)]

The resolution of the bug nebula is fantastic! The rest as well.

[Ryderscope (Rodney)]

We are wondering what the collective noun for a group of PNs is

Notwithstanding this, we have a fine collection that present a lot of great detail. An excellent bag of PNs to be sure.

Great work, John.
