Preface

I want to thank AlleyKat for his great eve-video creation tutorials which made the basis for further subject research.

Zoom and visual navigation

Almost everyone is aware of basic camera works in EVE client, like rotations, zoom (anyway it's covered in eve tutorial). Basic zoom (which is actually not a zoom but camera reposition) is performed by whether pressing and holding left and right mouse buttons (LMB+RMB) and moving mouse up and down or scrolling mouse scroll wheel. But there is one nice feature of EVE client like true zoom (actually changing the camera's focus distance in terms of optics). it's preformed by pressing and holding Ctrl+LMB+RMB and moving right(zoom in) and left(zoom out). That feature is nice when you do some fancy camera works and shoot eve movies, but it might be useful in other areas.

360 Sharpshooting

when you open 360 scanner and minimap (F11), you see two sectors in lowest section of minimap. Grey sector represents view sector, and green - scan sector.

When you press-hold Ctrl+LMB+RMB and move mouse to the right, camera zoom factor changes and grey sector dynamically reflects that change.

When zoom is maximal and scan angle is minimal - we have both sectors of the same size (actually view sector is a bit bigger, something around 7 degrees). These parameters give us sort of 360 sharpshooting setup.

Visual undocks

Horisontal

You should already know how to create undock bookmarks. You pick fast ship, undock, press max speed triangle, engage MWD and wait. When you have some distance from station (1500+ km) you create bookmark and be happy. The problem is that your BM might be slightly unaligned with undock vector. Some time ago CCP implemented random angle spread from undock vector. that unalignmet might lead to not instant warp off from the dock, especially when your ship is heavy BS or hauler or even freighter. But you can adjust your undock BM with zoom technique.

Warning: not all stations have their undock vectors aligned with axises of tactical overlay. Some Gallente and Amar bases have vertical down vectors, some stations have slight angle deviations.

When you are in hostile system, you don't even need to be on the same grid with station to recognize it by major structures layout to find undock vector. Here is zoomed view at FRP from over 4000 km distance.

If you already have some undock bookmarks, you might want to adjust them. When you don't zoom in, it looks like BM is ok.

But after zooming in the offset becomes apparent. If you are unlucky enough, aligning to BM might kill you.

All you need is to navigate the ship to make the full line of tactical overlay marks (400 km) to point at dock bay.

Vertical

Vertical undock bookmarks appear the easiest to create. It's because projection dot of a station on the tactical overlay doesn't vanish when you leave station grid. The same applies to gates and might be used to create vertical FlyBy BMs. The procedure is quite simple - it's preferable to have station brackets active. After undock one has to evaluate projection dot position relative to undock spawn point(and ship position). After getting to the desired distance and not loosing projection dot, its position should be recreated relative to the ship.

Vertical FlyBy bookmarks

procedure to create vertically aligned flyby alpha and beta BMs is similar to creation of vertical undock BMs.

Bubble BMs

With zooming technique on can create bubble BM with high level of precision.

Creation

At the time of writing bubbles showed the ability to affect warp exit point at the distance up to 200km. So we will focus on creation of the bubble BM positioned behind the gate and able to catch warps from celestial to gate up to @100km.

Small remark concerning bubbles around station - bubble position should be aligned with station anchor point (which is depicted by station icon)

  • Warp to the target gate(station) @100km from desired direction and jettison a container with some junk on arrival. That container will be our distance reference point.
  • Move behind the gate and gain desired distance of 180-190km from reference container.
  • Make rough alignment and then fine-tune the ship position. For best result move camera as close to the ship as possible(mouse scroll wheel)
    1. rough alignment with gates
    2. maximum zoom shows inperfections
    3. start moving towards desired alignment of gates' anchor points
    4. when alignment reached - adjust distance using reference container to measure distance. Ship navigation during distance tuning is done with approach(closer) and orbit@1000km (farther) buttons.

Reuse of BM

To use bubble BM one should warp to that BM and on arrival start approaching it to remove 2km deviation effect. That approach will introduce ship trajectory oscillation effect. To counter it one can perform approach to the gate and then again approach bubble BM - that technique will introduce oscillation along gate-gate axis which is perfectly acceptable. Ship is at position for deployment of "perfectly" aligned bubble.

Digitally precise navigation

Nav coord.jpg

Everyone ever creating bookmark might notice those lengthy rows of digits in BM creation menu. Those are the coordinates of current position inside current solar system. Every single system has sun in its coordinates origin. Axis X faces West, Y - Up, Z - South if you observe solar system with F11 minimap open (for N-E-S-W reference).
