Adventures in Video Astrophotography

 

Hello everyone! I have decided to try my hand at blogging and have put my thoughts and actions to paper (albeit electronic) for all the world to see.

Just lately I got hold of a Mintron 12V6HC-EX CCTV camera and linked it up to my Meade LX90 8inch SCT to see what I could achieve. Just to put you in the picture I recently built a small observatory in my back garden. My garden being south facing is ideal for obseving with fairly clear views from east-south-west with just the north being obscured by the lift up roof on my observatory.  The Scope is not mounted on a pier but on the heavy duty Tripod and the floor being raised off the ground flexes slightly if you move about so long exposure deep sky imaging is a deffinate no!

The Mintron seemed like a good bet so that's the road I chose. Trying to get info on how to set it up was a bit like having teeth pulled until, I came across the excellent sights by Dr. Steve Wainwright at  : http://x-bit-astro-imaging.blogspot.com/ and the excellent GStar (which I assume is a rebranded Mintron) site at: http://www.myastroshop.com.au/guides/gstar/index.htm#GSTAR-CAPTURE%20USER%20GUIDE

Both of these sites have a wealth of information, you just have to try to piece it all together and hope for the best. The Gstar software works a treat with the Mintron and I will let you know if I get the cable to work to control the camera settings remotely. Here's hoping.

Anyway last night 24/08/2009 I got some reasonably clearish kind of skies and I say reasonably because this summer has been terrible in Scotland! month after month of cloudy,rainy skies :(

So I got the scope nearly aligned and being anxious and impatient to get going and set the camera to Jupiter. The image was too bright so I turned the sense down and got a nice big disc and the four Gallilean moons no probs However no detail on the disc (still too bright) I assume this is a filter issue and will try to address this on later nights. I captured a short AVI and moved on to M57  WOW!!!  A nice big ring and the central star which I have never seen before even with my 12 inch Dobsonian!

Ring Nebula M27 in Lyra

On a roll now so off to M27 Dumbell Nebula. Again a big WOW this was spectacular so captured another short AVI (note to myself to upload to You Tube and post link) next was M13 in Hercules again very impressive. The rest of the night till 0100 was used messing about slewing and so on to see what the camera would reveal. Any way I am more than suitably impressed with this camera to explore it more so keep looking and we'll see what happens.

These images can only improve as I learn how to use the camera and how to process the images afterwards but not too bad for a start eh!

P.S. if you want one of these great cameras then talk to Bernard at:

Hi Geoff I've got a few questions?

1. When you say single image do you mean 1 single frame or was the final image a result of stacking?

2. What exposure times where used?

They are great images, truly a good camera you should be really pleased with them. I take it your camera does not have a fast enough shutter speed for Jupiter.

Well done again!!!!!
