Optionally shoot Delta 3200 at EI 1600. The tonal scale looks good enough for me.

For your first roll, I think you did a great job! Welcome to the magic of black and white. A few quick tips based on your inquiry:
a) Typically when pushing 2 stops (from 400 to 1600 ISO) you'll need to increase your developing time by an additional 75%. I agree with other posts above.
b) Ilfotec DD-X is not the cheapest developer and I've found it is optimized for use with Ilford Delta 100 and Delta 400 films. With Tri-X, I prefer using Kodak XTOL developer.
c) If I want or need 1600 ISO but don't want the usual grain and higher contrast that it tends to produce, I use Ilford XP2+ Super. It's a chromogenic monochromatic film, which means you'd send it off for C-41 color print processing, but "develop only". You can shoot the same roll anywhere between 200-1600 ISO and the exposure latitude is forgiving plus you'll get the least grainy, lowest contrast for 1600. Scans beautifully too.

Delta 3200 is ok at 800 or 1000 if you want low light use it or lose it!

Essentially, pushing a film two stops means underexposing it by two stops. Except for a couple of hard-to-find speed boosting developers, no amount of development will bring back the detail you lose in the shadow areas. If the film doesn't get enough light for the silver salts to record detail in the darkest areas, that detail is gone.
However, extending the development does bring up the underexposed highlights to something you can use. So what you end up with is a very contrasty negative, which can be handy if shooting under flat dull lighting.
I used to push 400 Ilford to 800 all the time when shooting outdoor sports on a dull wet day. The extra contrast helped snap up the otherwise dull light.
We used to push to 1600 to try to shoot hockey indoors (just because there wasn't enough light for anything slower), but the excess contrast and loss of shadows meant players' faces often disappeared into murky grain. The TMAX 3200 and Delta 3200 films were a huge improvement over trying to push 400.
Once when very young and foolish I learned my lesson when trying to push 400 film to 6400. My light meter said I making good exposures, but after development all I was left with was dots made by the light sources, and just about nothing else. All contrast, and nothing else. I never tried it again.
"Pulling" film is often a better idea than pushing. Exposing 400 film at 200, and reducing development results in lots of shadow detail, and helps tame excess contrast on bright days. You can always goose up the contrast in scanning or post-processing.

I got the lens recently and here is my first Milky Way attempt with it - I was quite happy with the result. I hope to get some more shots over the weekend when we go camping far away from the city lights. |

"Be Part of the 1.62%" or "Join the 1.62%" isn't such a bad slogan and plays off the whole "1%" debate that's happened in the U.S. and abroad on and off the last few years.

Updated design. It was another struggle, but there are no more duplicate images in the design anymore. Managed to squeeze in some flashes and big lenses too.

Had a package arrive in the mail the other day, and it came with two of the ol' Model 202's grandchildren in it. The reason I picked up those two 1.4's was because of the love of old manual glass that was an almost complete result from my weird predilection for Sears lenses.

Oh yea, I also can now shoot my 300mm stopped down. As soon as I get over the honeymoon with the 35 and 85mm's I'll definitely be putting my other lenses through their paces to see how they fare with the K-3's big honking sensor and lack of an AA filter. K-3 Moon by Jody Roberts, on Flickr

Finally managed a capture a photo of Comet Lovejoy with my new ES 127 apo scope and K3. The First quarter moon was very close to the comet and washed out the tail. Photo is 19- 30 sec. exposures 1600 iso and delayed shutter stacked with deep sky stacker.

Lovejoy again! but what a great comet. I don't think we've had such a great comet in the northern sky since Holmes 7 years ago. This was shot Tuesday night January 20th. Lovejoy with the Pleiades
smc DA* 50-135 mm f/2.8 @ 90 mm f/3.2. 42 x 20 s iso 2500. Tracked with O-GPS1 Lovejoy with Pleiades and California nebula
For this one my long trusted A 50 f/1.4 let me down. It did spend a few hours at -18°C before the shooting began
so it may explain why I couldn't find correct focus. But I don't remember having such a trouble in the past winters
25 min exposure in 20, 40 and 60 s shots @ f/2.2 iso 2500. Tracked with Pentax O-GPS1 |

Hi chaps, I'm just getting into this Astrophotography business, started out with a Haig mount and soon found limitations of that with longer telephoto lenses. So graduated to a motorised Skywatcher EQ5 with PC control, on which I have a K5 with DA300 and a 1.4TC.
I'm working from the eastern side of Manchester here in UK, so reasonably light polluted. This is my first serious effort with the new kit - 40 exposures of 2 mins each, plus darks and flats, stacked in DSS and finished off in Lightroom.
Hints and tips welcome...

OK, you guys inspired me to go out in the cold tonight and attempt to capture Comet Lovejoy. This is 11 frames stacked in Deep Sky Stacker with one dark frame. These are 10 second exposures at ISO 16000 taken with the K-30 and DA* 300 lens at f/4.5 (I think). The tail is just barely visible. Comet Lovejoy by loco's photos, on Flickr

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. |

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?

We started out with a Celestron C90, which is functionally a 1250mm/f13.9 Maksutov-Cassegrain MIrror lens that attaches byT-Adapter. Not fancy and certainly no computer controls but it has been fun for us. The main thing I found out is that a VERY solid tripod is essential. The model you are looking at is also a Maksutov-Cassegrain mirror lens but is a bit longer in reach at 1325mm f/13. The added computer controls should be nice and it comes with a telescope tripod which is a plus. I like OpticsPlanet better than B&H (love them for camera gear) for telescope stuff. Here is their page (same price but much higher knowledge base) with the full stats on the telescope you are considering. http://shop.opticsplanet.com/celestron-nexstar-4se-telescope.html? |

We got a Nexstar 5 SE for Christmas. It holds the K-3 without issue. We have been playing with it and the 1 1/4" adapters. The direct to T is on the way. We will probably slap the K-50 on it when we go out. I want to try some wide field with the 3. In short, the mount (same as the 4) has no problem handling a much heavier camera. With a smaller OTA, you may need to adjust the balance point, but the mount shouldn't be a problem.
