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 ASO 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….


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

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 go outside in the winder and freeze my tail off outside….


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…


I’m Back….I think!

It’s been a while since I last posted. The weather here has just been terrible and to be honest I have given up on trying to do Astronomy here in Cornwall.  Since my last post I have given variable star observing a go using the remote telescope network in the US. Yes, it’s expensive at about one US dollar a minute, but if added up what I have spent on my observatory over the…


Observing Session 16, January

It’s been a while since I got up at ‘Stupid O’Clock’ to do a bit of observing. But waking at 3am and feeling reasonably alert, a peek through the window confirmed perfect observing conditions and too good an opportunity to miss. Of the three Collinder Clusters I observed this morning, fate chose ones ones with huge 2 to 3 degree diameters, so for once all these had to be observed using the TMB. In retrospect,…


Observing Session 7, January

The first clear night of the year – although for only a couple of hours before the slow moving cloud started to roll in. Despite not having used the scope for two months, mount pointing was pretty accurate – with the first slew-to object only just outside the FOV of the 40mm. However, I wasted most of the session trying to keep the network up long enough to be allow the observing notes for Skytools 3…
