Orion 10 inch Dobsonian on Equatorial Platform, and my imaging setup.
Processed version of my B&W photo M42 Orion Nebula from 4/1/2020 – lights and darks – I didn’t have any flats to hand.
This image has been taken with ca. 30 light frames only 5 secs long, showing how much more sensitive the Altair 183M mono camera is than my QHY10 one shot colour camera!
This post follows on from previous post below:
Next step in my astrophotgraphy journey has been today to lay the stones in the garden to identify where to place the imaging setup for imaging sessions so that it is close to polar alignment – I can then use my QHY Polemaster to do the rest!
Angella and Alan took me to a reclamation yar last week where we chose 3 cobbles with a reasonably flat side on one edge.
I have laid them just below mower height in the grass.
First Light for my EQ6 astrophotography setup on homemade mobile wooden base on carrots. Worked very well worth Polemaster to polar align scope – once I’d worked out which was RA axis! 20 mins of embarrassment when I turned the declination axis instead during the Polemaster routine!! Photographed Eastern Veil and to lesser degree Pleiades (lot lesser) whilst Damian came around about bought that wonderful Bord refractor he purchased recently. It is a great little scope with wonderful views and quite a bargain! Damian is quire critical of this little scope but then he is comparing it to his Takahashi 104 which he describes as “snapping onto focus” but I think it is brilliant and, for the money he paid, a great investment. He wouldn’t have got a Takahashi for that price and been prepare to use it as a travel scope either. It delivered great views of Auriga clusters and Double Cluster and M81/82 amd Ring Nebula and seemed well matched his 20mm Pentax 70 degree AFOV eyepiece.
Attached photo is me taking flat frames on my setup.l – QHY10 + Tele Vue field flattener + Sky Watcher Equinox Pro 80mm OTA ON sky watcher EQ6 mount.

At last! My mobile base for my EQ6 is completed. Someone will note slightly extended legs and wonder why…..answer is that base is designed to take either EQ6 as is currently on it or HEQ5- and the tripod on HEQ5 (same as EQ5 tripod but different from EQ6 tripod) has long legs and wider spread than EQ6 tripod.
Two layers of Cuprinol later (left over from my wife’s fence painting project earlier in the year), the new mobile wooden HEQ5/EQ6 will be ready for vanishing with yacht varnish once it dries – and with high humidity levels at present and low temperatures I think it might take a few days before it properly dries out from the water based Cuprinol. That’s the price you pay for using left over stuff!
Now that I am doing astrophotography, it is important that I create stable, mobile base to allow me to roll the mount in and out of the log cabin. The more that can remain set-up between sessions, the easier it will be to image – especially important in the UK as weather liable to deteriorate again quickly.
Angella & Alan came around today and helped me build a fantastic base – thanks Angella & Alan!
