Great shots everyone - First time I've used the scope in about 3 months last night! Decided to have a play with C/2014 Q2 Lovejoy here in Mackay. Couldn't get the tail with the ED100 at F7.65 last night so gonna give it a go with the 70-200mm at F2.8 tonight I think.

Here are my shots of the geminids. K-30 with Rokinon 16mm f2
It was clear here in Palm Springs and it was the best shower I've seen in a while. The 3rd image is a composite of 17 separate shots, each with a meteor, stacked in StarTrails.

I did a few tonight from my mom's place. The Orion nebula one was taken with my K3, Sigma 150-500, O-GPS1 doing astrotracer, and a cheap Sunpak tripod from Best buy. I see the weak link in the mix, my tripod. Ohh boy was the tripod the weak link here. I also overexposed. The moon was also with the K3 and Sigma 150-500 and the wide star fields were with the K-01 and Sigma 18-35. I have some from that setup I am going to run through DSS and see what happens.

C/2014 Q2 Lovejoy - Imaged on 2015-01-08 at 9pm AEST from Mackay. Unfortunately conditions were not good with near constant cloud so only managed 1 frame before the cloud came in. Needless to say the detail in the tail now is incredible!

Nice photo! Did you use the SSAG to track the comet or did you set it to track the stars?

Thanks Obin! Nah I've got a full telescope setup I attach the K-3 to - it's a Skywatcher ED100 telescope with NEQ6 Pro mount to track the stars (all computer guided).

Here's tonights image of Lovejoy - much fainter tail - I used the Sigma 70-200

Comet Lovejoy and K-3 with O-GPS1 plus Pentax FA 1:1.4 50mm

I cannot compete with weathermoon's Lovejoy images but I finally had some precious moments of clear sky the night before yesterday. Clouds were already approaching when I got out, so I only had some 30 minutes and no time for elaborate set-up and searches with longer lenses. I therefore decided to try my luck with my 50mm lens in the hope, that I would get at least some kind of memories from this comet's visit to Northern Skies.

Here's what my urban sky looks like:


Comet Lovejoy on 11 January 2015 near centre of the image, which is an approx. 25% crop of a single exposure of 20 sec. with FA 50mm @ f/2.8 and ISO 640. Click to see 40% crop.

Obviously, with this kind of light pollution there is little point in searching for the comet's tail and, furthermore, the comet moves quite swftly and with the O-GPS1 one can only track the motion of the stars - not that of the comet.

Anyway, here's an overlay of my first and last picture taken 19 minutes apart. Quite a fast mover, isn't it?

Finally had time for a quick shot at Lovejoy. The comet is now really bright and huge! The tail could not be seen with the unaided eye but the comet itself really easy to spot. The tail showed up on my first 20 s test shot! 5 X 60s iso 1600 with my A 50 f/1.4 @ f/2.2. Guided with O-GPS1. Click on the image for higher resolution.

That's really cool, SunValley! I'd love to give it a try, but it's sooo cold. And I'm a wuss. You did a fantastic job!

Very fine images zambonikane!! I wish I had access to such dark skies. The Milky Way picture is gorgeous.

Well, I don't have dark skies near me, so here's something very different.......

All stars are point-like light sources --- except for this one (clik on images to see larger versions):



K200D + Tamron Adaptall-2 series SP Model 54B lens + Tamron SP F-series 2 X Teleconverter. 600mm FL, f/11 @ ISO 100. Taken with the use of Solar filter foil from Thousand Oaks




Approx. 300% crop of original image.
Resurrecting an old thread because I just found that Stone used a Tamron SP 300mm f5.6 (model 54B) for his solar images (on page 7 of this thread). Somehow this lens has escaped my notice until just recently, but it sure looks like it deserves a place in every Pentaxian's arsenal. A lens that is fine enough to do astro images AND close focusing/macro images and for under $100 is a no-brainer! The "slowness" of the lens is less of an issue with the high-ISO performance of today's Pentax also! (My 54B will be here in a couple of days. I found it for $79/shipped!)

Many thanks! Don't let the cold hold you back, I was out in -29C (-20F) temperature for 40 mins and had plenty of time to take the pictures.

Here are my attempts at Comet Lovejoy. I used the FA50 1.4 with almost the same settings as Sunvalley, but I have no tracking device, so my exp. was about 8sec, F2.2, iso1600 with a K-30. I was surprised how easy it showed up in my first shot.



Then I tried the Auto Sears 300mm 5.6 prime. Again with no tracking, my exp. was about 5sec at iso 10000, F5.6

Good things happen if you wait long enough! I went out to get some more shots of Comet Lovejoy and as I was packing it all up for the night, I tried one more shot with some tress in the foreground. And what to my surprise shoots across the screen? A meteor from what I think are the Anthelion showers and comet Lovejoy in the top left. Ahhh, victory is mine!
