Processing NGC6744


Avid amateur Astronomer with multiple Interests

After completing a 200 point pointing model of one of the telescopes in the Atacama Desert in Chile, I tried to image a target that was well suited for this telescope. It is an absolutely stunning telescope with only premium components, it consists of:

Mount : Nova120 direct drive

Telescope: ASA 16" Newtonian

Camera: FLI Proline16803

Capture and Processing: PRISM v10 ( of course :-D )

Joaquin's telescope

Exposure details

Since this is quite a bright nebula, I thought about only using 300s exposures, having it available to image for close to 8 hours that night, I did invest the entire night in it.

The details are:

L: 300s x 50

R: 300s x 12

G: 300s x 12

B: 12 x 300s

typically I add Ha to a big galaxy like this to really capitalize on the galaxies within, but I do not remember having done that.


The typical process involves capturing the data with PRISM as well as pre-processing. For post-processing, PRISM is very capable of accomplishing this task. However, it is not designed to replace the likes of Photoshop. Instead, it provides a quick and powerful way to edit images and publish if that it what you wish to do. 


Pre-process with PRISM. Apply the bias, darks and flats to the image easily and automatically


Align the channels with PRISM. This is the process where PRISM align the LRGB frames using the stars in the images


Export from PRISM to Photoshop as a TIFF 16bit.


Post-process with Photoshop and publish.

Imaging Made Easy

Prism is my GoTo program for observatory control and imaging. Prism's many features make imaging taking a breeze.

I was concerned about giving Prism a try , especially as its quite expensive. So far Im very impressed and glad of my decision.
Im a beginner at all this so haven't tried other more recommended software, Prism appealed as it seems to do everything instead of using several programs 👍🏻

Great lightweight guide scope

This guide scope replaces a 400/80 that was waaay too heavy for what it did. The smaller 60mm scope does a great job guiding and I can RA balance with just one counter weight now - much better - and it looks like something Ferrari designed

Still learning Prism using Wireless links...

I have much of your software working at this time... I have it parked on my main computer, and a notebook... My main computer is a OverClock computer with 32 Gigs of RAM Clocking presently at 4400MHz with software parked on SSD drives... The rotation dome by NexDome is still not working... Most problems like this have to do with ASCOM Drivers... There is not very much detail information on how to use this software... I have to feel my way to a total operational staus... Second issue... The rain in the San Francisco Bay Area this year has limited my access to my larger telescope (12 inch SCT)... This rain has been so significant, I was force to weatherize my observatory... My goal here is,,, I am trying to remotely control my observatory totally. I have used Netgear Powerline 2000 to handle camera images and discover controlling rules to do that... High speed is vital for images with cameras over 3 Megs... I have both 12 Mega sensors and 24 Mega sensors... I am also using Netgear Nighthawk router and its mating extender to increase control signals to my observatory that is about 100 feet on the side of hill... I am also using Virtual Here software on a Raspberry Pi inside the observatory to solve the USB interface requirements... I started out using Model B and B+ on level 3 raspberry Pi's... I have moved to Level 4 Raspberry Pi to gain access to USB 3.0 technology... Big difference! I hope by early spring to have everything working... Bob Ritter MicTechS

A great program, even for beginners!

I have to admit, I was hesitant to invest in an “all in one” astrophotography program. Being a beginner, I thought the learning curve would be way too steep, but after talking with several friends I decided to give it a try. The first thing I noticed was the logical layout of the main screen. It was very intuitive and easy to navigate. Everything you could need for astrophotography is in this program! Setup of my equipment was quick and easy with no glitches or errors. Everything runs smoothly from capture to the final process. You will surely have questions and this brings me to the next point. Prism’s customer service is second to none! With on line tutorials, a Facebook group and email you will have instant access to knowledgeable users worldwide. My first question was answered directly by the US distributor within a matter of minuets! Take the next step and invest in your future in astrophotography! You’ll never look back!
