Thanks! Yes, top image is from 2005. I'll post a crop of the central region of the new one to compare later.

Last post by Carole - Feb 09, 2024, 10:26:49That's gorgeous Roberto, especially full sized.
Did I understand correctly that the top image was in 2005?
The planetary Nebula is amazing.

Astrophotography / A Heart for Valentine's? IC18...
Last post by Roberto - Feb 07, 2024, 19:10:21Hello All
Just managed to fit the Heart Nebula and most of the Fish Nebula into the FoV of the Moravian C5 at 918mm EFL. My best and last shot of this object in HaRGB was in 2005(!!!) using a Starlight-Xpress SXV-H9 and C9.25 from west London. See below...
I wanted to complete this in narrowband but with RGB stars. Unfortunately the FoV of my OSC camera and smaller refractor is smaller than for the C5 and larger one so had to do some processing acrobatics to get RGB stars and NB stars together (bands at top and bottom of final SHORGB image).
The NB palette was a mix of SHO and HSO.
There's a really nice looking object towards the centre left of the main nebulosity which turns out to be a recently discovered planetary nebula called WeBo1.
"This object was first noticed by Ronals F. Webbink 1995 when searching radio sources. Later it was optically reviewed by Howard E. Bond at the 0.9m Kitt Peak National Observatory."
IC1805, IC1795 - SHO with RGB stars - and WeBo1

Last post by Roberto - Feb 03, 2024, 20:21:41Hello
A couple of nights in January and a couple in February allowed me to capture this nice face-on galaxy in Ursa Major close to Tania Australis. Quite a few reflections from the bright star to deal with in the older StarFire EDF. The newer Stowaway seems to have dealt better with the brightness although I was shooting half the exposure (at 5 mins OSC). Taken using the usual tandem arrangement.
There are many, many background galaxies in the annotated version. A cluster of background galaxies, towards the lower centre right is ACO 971 which according to Simbad's database is 1.3bn ly away.

Last post by Carole - Feb 03, 2024, 15:09:14A few of the OAS people who are not regular imagers have bought one. But thus far they are only doing very short subs with them.
I will put this on the next members images and show what longer subs can achieve.
In particular l will mention this:

Last post by The Thing - Feb 03, 2024, 06:57:43It's a little device like a large hardback size which connects via Bluetooth and WiFi to a tablet or phone for control. Very portable.
It's robotic because if you disconnect it keeps imaging. Also very good for daytime e.g. panoramas, object tracking, time lapse.

Last post by Carole - Feb 02, 2024, 21:13:13When you say robotic telescope, do you mean it is yours but works like a robot, or that you accessed it remotely.
It is certainly impressive for 15sec subs.
These are certainly clever imaging scopes and would be useful for travel.
