NGC 5457 – M101

Session Data Date:  31/03/2020  Time:  21:50 – 22:45 UT Seeing: II Mostly Stable, Transparency: Mostly Clear, Temp:3.1C, Air Pressure: 1028mb, Humidity: 75%, Dew Point: 0C, Wind Speed: 8mph Scope: TMB 80mm APO Refractor at f/4.8  Camera: ZWO ASI 1600MM Pro,  No filter, Dark subtracted, No Flats. I guess I’m safe to say that this is the first true first light image for the new camera setup. Clear skies, a bit of a breeze and a 7 days old Moon….


NGC5194 M51

Session Data Date:  02/04/2020  Time:  21:40 – 23:44 UTSeeing: II Mostly Stable, Transparency: Clear, Temp:3.9C, Air Pressure: 1020mb, Humidity: 88%, Dew Point: 3.9C, Wind Speed: 5mph Scope: TMB 80mm APO Refractor at f/4.8  Camera: ZWO ASI 1600MM Pro,  No filter, Dark subtracted and Flat fielded. Still more testing tonight. A stack of 53 x 60 sec lights. I didn’t shoot any flats at the time, but realising that I had not touched the camera for a few weeks, that…


C2019 Y4 ATLAS

Session Data Date:  31/03/2020  Time:  21:50 – 22:45 UTSeeing: II Mostly Stable, Transparency: Mostly Clear, Temp:3.1C, Air Pressure: 1028mb, Humidity: 75%, Dew Point: 0C, Wind Speed: 8mph Scope: TMB 80mm APO Refractor at f/4.8  Camera: ZWO ASI 1600MM Pro,  No filter, Dark subtracted, No Flats. Just a quick hop over to see if I could pick up C2019 Y4 ATLAS. Managed to take 60 x 30sec lights. I kept the subs short as I didn’t want the Comet or…


NGC3031-M81

Session Data Date:  23/03/2020  Time:  20:53 – 23:22 UTSeeing: II Mostly Stable, Transparency: Mostly Clear, Temp:5.5C, Air Pressure: 1023mb, Humidity: 85%, Dew Point: 3.5C, Wind Speed: 8.5mph Scope: TMB 80mm APO Refractor at f/6  Camera: ZWO ASI 1600MM Pro,  No filter, Dark subtracted, No Flats. A total of 73 x 60sec light frames which have been dark subtracted. I wasn’t really worried how this turned out as this session was more of a test of how PHD was performing….


First Light

Managed to get an evening before sunset with the Moon up, to really give the camera and focuser a good test. The biggest high of this whole session has been the electric focuser. You can do all this remotely and in the warm and I can’t believe how useful this bit of kit is. I’m reminded of the focusing sessions in the old DBO1, where I had to stand on a short ladder, while…


It’s on

Well I have coupled everything up. I’m not an amazing fan of OAG’s but I had one in the spares box and just thought it was simpler to try it out.  In the end it was all for nothing as I couldn’t get both the camera and guide camera into focus at the same time.  I should have got loads of spare spacers and adaptors when I got the camera so would have been…


New Toy Time hi

Look what the postman has just delivered. Having seen how successful all my astro friends have been with their new One Shot Colour cameras, I decided to join the them. While the plan is not to use this for taking really deep sky images, but rather allow me to use it as an aid in my various visual projects, when I can’t be arsed go outside in the winter and freeze my tail off…


NGC 224 -M31

I finally managed to get a good spell of clear weather in New Mexico. M31 is such a popular target for imagers and we see so many images of it, but it really does suit this scope and camera combination. I also wanted to practice my processing skills in Pixinsight, especially as colour is not something I have done much of. This is an assembled LRGB image. The luminance consists of 11 x 300…


IC5146 Colour

I’ve managed to acquire the colour data for the Luminance image acquired last January. The RGB date comprises of 7x 3min subs for the R,G and B channels. I initially processed this as an LRGB image, but wasn’t happy with the result, so I overlaid the RGB data over the top and created a hole in that layer for the LRGB section of the nebula to show through. Yes, the stars are a little…


iTelescope

My first deep sky image using the scopes on the iTelescope remote network. The images were taken over two days on the T14 and T20 scopes in New Mexico. Both scopes use the same Takahashi 106mm refractor and SBIG camera. The great thing about the remote iTelescope network – apart from the obvious dark and clear skies in places like New Mexico and Siding Spring, is that the raw FITS files you receive are…
