I wasn’t able to get out to the park last night but once the smaller of the children was abed & the teenagers uploaded to their games I popped on a hoodie (cunning anti-security light plan) and decamped to the garden, wine in hand, for an impromptu after dinner tour with the ST80.
After wrestling with the old wooden tripod on my “new” Prinz 330 60mm earlier in the week, the Manfrotto 55 and full height viewing position made this feel quite the luxury experience!
Wide-field views weren’t bad either...
15.4, 9.30 PM
ST80 & Baader Zoom.
Seeing good, transparency patchy at Zenith, murky below 30 degrees.
Castor - almost split @50x low over rooftop
M44 Beehive - great view, put the red dot right on it. Was above the houses & enjoyed the soundtrack to a neighbour’s party whilst lost in space.
Melotte 111 - lovely view. Super round pin points & some good colour contrast with white & a smattering of orange stars. ST80 loves these slightly fainter clusters. No hint of CA. This cluster now firmly on my highlight list.
Chertan & 73 Leonis - but no triplet (well it was worth a try)
Algieba - Split (just) at 50x, nice yellow headlights.
Had a look for anything apparent in the Virgo galaxy field but lots of white LP to SE so no chance.
Cor Caroli - beautiful view in the ST80. White primary with smaller fainter white secondary - nice round stars.
Mizar - again a super field, Mizar A&B look a close pair at 50x with size contrast - easy to imagine as an orbital system. Alcor a way off and a couple of other faint stars making a nice little asterism.
M81 & M82 - yes! From the garden, a first outside of M31! Hoodie over the EP. Dropped the red dot carefully in line from the diagonal across the bowl of the plough/dipper. Galaxies popped with a slight nudge from original guess. See an oval and a stripe & that fantastic orientation - obviously no detail but a rewarding view from among the security & streetlights!
Enjoyed for ages with a glass of wine!
Civilised galactic travel...
This is a lens that does not need an introduction, it's simply a fantastic budget lens! I've been using it for astrophotography with great results and satisfaction (see pictures). Just selling it becuase I'm upgrading to the 135mm version. Any questions please ask. Asking £160 which includes P&P to UK mainland.
Hi everyone, not sure if this is the correct forum for this thread but thought it was close enough to topic 🙂
In prep for my Pulsar Obsy build a couple of months from now I’m looking to get ahead of software requirements for the dome. Can anybody provide advice on a decent ‘Skinny’ software stack for mount and dome control. Observing has been simple for me thus far, only need to worry about mount control. However, I got to thinking about how clumsy and inefficient things would be if goto commands were two separate unrelated actions one for mount control from my chosen planetarium software SkySafari, and then having to reach over and key in the Azimuth setting for dome position. As far as I know there is no dome control interface from SkySafari, so it looks like this will be achieved via an RDP session into my Intel NUC and thence to the dome controller. No big deal I guess this will just join my Atik Horizon control Software. What is my best solution for joint mount and dome control?
I have recently acquired a Vixen Polarie with the intension of doing some wide field imaging,
I will be using my modified Canon 600D with it, Currently the only lens i have are a standard kit Canon 18-55mm and a old carl Zeiss Jenna 50mm , so i am looking at purchasing alternative lens to use,
The ones i am looking at for now are the following,
Canon EF 135mm f/2 L USM
Canon EF 200mm f/2.8 L II USM
Samyang 135mm f2 ED UMC
Samyang 14mm Ultra Wide-Angle f/2.8 IF ED UMC
Sigma 150mm f/2.8 APO EX DG HSM Macro
Tokina 11-16mm f/2.8 AT-X Pro DX
So my question is, has anyone used any of these ( other than the Samyang 135mm f2 ) for wide field and if so how did you find them, would you recommend any of them?
from the ones listed (other than the Samyang 135mm f2 ) would you say there are better ones to look at or any other i should consider?
