Bullet Deep Sky Challenges (List)

Some targets were imaged as a direct response to seeing the respective challenge and taken either in the during the magazine edition's Official Month or during the month beforehand when the magazine edition first appeared). Other targets are ones that I had either already imaged sometime before the publication date or ones that I have independently imaged at a later date.     More recently I have set myself the objective of going back to attempt to image the Deep Sky Challenges Targets that I haven't already imaged.

Whilst some of the challenges are set with the visual observer in mind and some are specifically described as 'Beginners Challenges'  other  targets are solely the preserve of CCD imagers.  Probably the most challenging object in the 'list' so far is the mag +20.4 quasar PC 1247+340 (redshift 4.897) that appears in Apr 2007 edition,  I've made two firm attempts to image this quasar so far but without success.

Abell 31 (Feb 2011 challenge), Simeis 147 (Nov 2013/Feb 2009) and NGC 7094 (Sep 2017) are very difficult to see and image.

Oct 2017 Challenge : NGC 100 - Edge On Spiral Galaxy

This super-thin galaxy in Pisces has imaged close to full moon. It could benefit from being reimaged under darker sky conditions.

Sep 2017 Challenge : NGC 7094

This is apparently one of the most challenging planetary nebulae to observe in the NGC catalogue.

Image below were taken in Nov 2017 under near full moon conditions. The planetary nebula is just about visible. Total exposure time is 2 minutes.

(Earlier attempts to image NGC 7094 were made in 2004 and again in 2007 with 8" LX200 and CCD Camera. Although the mag +13.6 central star could be easily seen, the planetary nebula could not be detected in images of 6 minutes total exposure time).   )

Abell 33 /  PLN 238+34.1  (Hydra)
 Planetary Nebula is unfortunately not visible in the image due to the object's very low
surface brightness and prevailing bright moonlight (87% phase). 
The catalogue position and extent of the Pl.Neb is shown by the white circle.
The bright star directly south of the nebula is the mag +7.2 star HIP 47369.

Sep 2011 Challenge  :  Seeing southerly stars 

The challenge in September 2011 edition of Astronomy Now was to try to see the most southerly possible star from the observers latitude.

To try to keep with the original  'Deep Sky' theme for the challenge series, I've interpreted this challenge as an attempt to image the most southerly possible deep sky object from my Aberdeenshire observatory. My latitude (57° 19'), makes it impossible to see any object with Declination  more south than -32° 41'. But even objects of Declination -32°  to -30° are a real challenge to see due to the high airmass & occlusion by low haze/distant clouds.  So far the most southerly deep sky object I've imaged is M83 at a declination of -29° 52' (2000).

Oct 2010 Challenge  :  Maffei 1 and 2 

Maffei 1 / UGCA 34 (Cassiopeia)
Eliiptical Galaxy - near centre of image

Maffei 1 (10 mly distance) is a galaxy lying in the plane of the Milky Way 
and is largely obscured by dust.  
Maffei 1 discovered in 1968 by italian astronomer Paolo Maffei, using infrared film
Note : Stars in near centre form part of open cluster Czernik 11

Maffei 2 / UGCA 39 (Cassiopeia)
Maffei 2 (10.0 mly distance) discovered in 1968 by italian astronomer Paolo Maffei, using infrared film
Maffei 2 is a galaxy lying in the plane of the Milky Way and is largely obscured by dust.  
Two sets of images of Maffei 2  were acquired (one set through Visual (V) and 
one set through Infrared (I) filter). These showed that the galaxy was visible in infrared , 
whilst at the same time practically invisible in visual band.

Pease 1 - Planetary Nebula in M15

Pease I (Pegasus)
Pease I - a planetary nebula in the globular cluster M15 - is the 
small 'red' object whose position is indicated by the white cross-hairs
This false colour image uses Ha filter frame for red, 
and V filter frame for blue and green.
The Pl. Neb. is highlighted due to its high excess of light at Ha wavelengths, 
and appears 'red' compared to normal stars which appear whitish.

Apr 2007 Challenge : Quasar PC 1247+340 - Attempted Observation

Star-field around Quasar PC 1247+340 (Canes Venatici)
Quasar PC 1247+340 (redshift 4.897) discovered in 1991 
was for a while the most distant object known. 
At magnitude +20.4 the quasar is too dim to have been captured in 
this 15x3 min exposure (extreme mag limit ~+18.9).
