After a busy weekend and several sessions where I’ve either been trying to take photos or improve my skills at finding objects I thought I’d have a bit of a night off, let the mount do the work, and just enjoy observing a few objects that I’ve been inspired to look at by other reports on this site. The setup for the evening was HEQ5 mount using the Wifi dongle, with the OTA from my 200p Dob (now working well on this mount due to extended counterweight bar- thanks Pete) and mostly with 40, 25 and 7mm EPs.
After a cold day the seeing was pretty good but the moon was bright so I decided to focus mainly on clusters. The objects were:
- I started off during the alignment trying to see if I could spot Sirius’ companion, but no joy.
- M35- looked good in the 40mm
- M46- looked good in the 25mm, spent some time looking for the planetary NGC2437 but couldn’t find it, possibly due to the bright moon which wasn’t too far away in the sky.
- M47- very pretty in the 25mm.
- M48 – another new one for me- loved it in the 25mm
I then spotted that Uranus was still just visible from my location so I put the 7mm on and spent a while observing it. I’m still not quite sure if I imagined the green hue or whether it was really visible. Having moved onto solar system objects I thought I’d have a look at Ceres but couldn’t find a way to get to it through the Synscan app on my phone. I was getting a bit cold so I headed in to see if I could work it out and also warm up a little. The way I eventually managed it was by connecting Sky Safari to the Synscan app, however in the hour I was inside, the mount seemed to have moved a little out of alignment and it proved quite fiddly to get to the object- some thoughts on this below. I then returned to clusters:
- NGC2264 – The Christmas Tree Cluster
- NGC1502 – Kemble’s Cascade – needed the 40mm for this one, but very pretty and brilliant to see it with my own eyes after failing to star hop to it a couple of weeks ago.
- Eta Cassiopeiae
- Garnet Star- this was just visible from my location, a stunning red and a great way to finish off the session.
Some thoughts on the WiFi dongle:
This is my fifth/sixth session using it, and whilst I’m still very pleased with it (especially the ease of setup) there are a couple of reservations from the last couple of sessions, primarily based around touchscreen devices in the cold. First point is that the battery level drops much faster in the cold, even when putting the phone in your pocket between adjustments- you really need to make sure there’s a good level of charge before you start. Secondly, the touchscreens seem to become much less responsive in the cold, often needing several “presses” to make them work and on one occasion still seeming to think I had my finger pressed on a button long after I’d let go, resulting in the scope slewing way across the sky away from what I wanted to look at. This is all quite frustrating and can be a bit fiddly. I didn’t experience any of these issues in the first few sessions, where the temperature was 3-6 degrees, but in the last couple where it was zero or below it was really quite frustrating. On the upside, having SkySafari connected to it was brilliant and quite straightforward to do.
