M42 - H-Alpha

I bought an H-Alpha filter from Astro Fest yesterday. I thought I'd give it a go on M42 and see what I could do. The light pollution around where I live is beyond awful and I don't have any fancy pants CDD camera - just a humble Canon 350D. I'm also very new to process deep space images, having only...

M42 - Orion

I thought I'd try my hand at photographing nebulae for the first time . Not having ever attempted to do something like this before it was all rather experimental and a little hit and miss. I got a little excited when I saw the first image of M42 on the LCD of my digital camera and promptly forgot to...

Guide camera

I'm having trouble seeing faint stars with my current guide camera. I have an Optic Star 130M. Does anyone else own this camera? For example, when trying to guide my 'scope on M31, the Optic Star camera is unable to collect enough light from any stars near M31 and therefore I am unable to guide my m...

M31 - autoguiding

I was going to try M31 last night as well but there were no stars bright enough near to it for my webcam to pick up. Real shame as I'm dying to image M31. I'm using a Opticstar M130 webcam which is more suited to planetary imaging which is probably why it isn't senstive enough to pick up really fain...

Orion Ultra Block filter

Hi all, I've had an Orion ultra block filter for a while now and I recently started using it on my William Optics Megrez 110 doublet refractor. I normally don't do long exposure astrophotography but I started last night and I noticed something odd about the filter. I am mostly photographing open clu...

M45 - Pleiades

I spent the night testing out my new autoguider set up and my subject tonight was M45. This was the first time I've been able to image for more than 30 seconds. The autoguider I have is a Opticstar M130 web cam which is fitted to my PC. The PC in turn is fitted to a Shoestring GPUSB controller which...

What telescope

Malcolm,
Great shot. What telescope did you have your DSLR attached to and did you have an eye piece or barlow attached to the 'scope at the time of photographing or was the camera shooting straight through the scope?

Guiding

Did you use a guidescope whilst taking this photo to maintain accurate tracking or did you initially set up your alignment very accurately using the drift method?

NGC 869 & 884 - Double Cluster in Perseus

This is my first proper deep space photo taken with a Canon 350D attached to a William Optics Megrez 110mm refractor. I took 15 exposures at ISO 400 for 30 seconds each. I then processed and stacked the images in DeekSkyStacker, a free piece of software which allows you to manipulate and process RA...

DSI vs 350D

Hi Killerwolf, The 350D has a much larger sensor compared to the DSI so it's easier to photograph "stuff" and of course you can cover a larger area of sky (but of course that also depends on your 'scope). The DSI most probably has a more senstive/responsive sensor especially for frequencies which ge...

Rings

Oh good idea about the guidescope rings! I have them already. Will try this out on the next clear night. Good suggestion, thanks!

Bright enough in a webcam

Great photos. How do you get faint stars new subjects such as the M32 to appear bright enough in your guidecam to be able to track them? Even with all sliders maxed out I can never seem to pick up a bright enough star... really annoys me!

BBC Article about Lucky

Hi all, I read this article on the BBC News web site today. Seems very similar in some ways to what amateur astronomers have been doing for years using cheap web cams. Obviously this new joint project between Cambridge and Caltech uses significantly more advanced equipment but in principle it strike...

Megrez 110 Doublet quality

Jonpugh114, I got to test out the Megrez 110 doublet last night for the first time since I bought the telescope last week. I was most impressed. I took a look at M57, MGC 6826, Alberio double star and M3. They were all clear and vibrant. I also managed to view Jupiter. I did notice some chromatic ab...
