EquipmentPentax 125 SDP with dedicated reducer at f 4.9 connected to Finger lakes proline 16803, Takahashi FCT 100 as guide scope using ST 7xe
DescriptionThis shot was "first light" using my Pentax 125 SDP and it's dedicated reducer. This reducer provides an 88mm fully illuminated image circle at F 4.9, extremely fast for a 5 inch refractor...with the incredible 88 mm image circle. Using this reducer, I'm able to obtain a 206 x 206 arc minute field of view...truely astonishing for a 5" refractor

EquipmentCelestron 80ED refractor at f/7.5, Meade DSI Pro II CCD camera, Schuler SII, Hydrogen alpha, and OIII filters, Meade LX90 guided mount.
DescriptionThis narrowband filter image highlights an advancing boundary of cold gas transforming into hot gas emissions from the radiation of nearby stars in the Pelican Nebula, IC5070. Red and green represent ionized Sulfur and Hydrogen. 3 hours 22 minutes total exposure.
EquipmentTelescope: 11" Celestron NexStar with f 6,3 foc.red. Camera:SBIG ST-2000XM. Guiding: SBIG AO-7 working at 5 herz. Filters: Standard RGB SBIG filters.
DescriptionThis is a dark cloud near to the great nebula of Orion M42-M43. It is not hard imagine why it`s called a Horsehead nebula. Total exposure time was 3 hours. This is a RRGB image where the lumenence channel was exposed thru RED filter.
EquipmentPentax 125 SDP at F 6.4 with Finger Lakes proline 16803 ccd Astrodon 50 mm square halpha filter
Descriptionthis is a first light shot taken with my new Pentax 125 SDP refractor and Finger Lakes Proline 16803 cam It is a combo of 4 subexposures totalling 105 minutes The field of view is simply amazing ! The Pentax is native F 6.4 focal ratio, and the new Fli 16803 chip ccd is definately H-alpha sensitive, and has excellent QE,

Equipment102mm wide field refractor (500mm @ f/5), Canon EOS D10 camera. A series of 12 exposures, stacked and processed in PhotoShop CS. The nebula's heart (trapezium) is a 1 minute exposure.
DescriptionA combination of emission and reflection nebulae.

EquipmentMeade DSI PRO II behind 10" LX200R @ f3.3
Description8 panel mosaic taken the night of November 17th under fair conditions. All images were taken with 2min intergration times. Lum images contains 10-20 stacked frames per panel. used H-alpha for red. All combined in PS
LocationDeer Run Observatory, Georgia
Equipment12.5" RCOS mounted on a Paramount ME. Camera used was an SBIG 11000M.
DescriptionThis is nearly 10 hours of data, including 4 hours of Ha data (to bring out the nebulosity in the spiral arms) taken on 4 different nights in November, 2006.

EquipmentPentax 125 SDP at F 6.4 prime focus imaging with Finger Lakes Instrument Proline 16803, Finger Lakes Instrument CFW 4-5 50mm square filter wheel with Astrodon 50 mm square 6nm HA filter,Pentax 75 SDHF guide scope using SBIG ST 7xeall riding atop an A/P 900 gto mount
DescriptionThis shot illustrates the tremendous field of view the new big chip cameras offer ! With my Pentax 125 SDP, that provides an amazing flat field at F 6.4...the field of view is 158 arc minutes x 158 arc minutes...literally 3 degrees square !!! from a 5" refractor. Additionally, this was taken at a forrest preserve less than 10 miles North of Downtown Chicago, showing just how powerfull, H-Alpha imaging can be, even from light polluted skies ! The image was 90 minutes long consisting of 3 frames of 30 minutes each. The original FITS file of this image is 64 MEG !!!

EquipmentCelestron 80ED refractor at f/3.8, Meade DSI Pro II CCD camera, Schuler Hydrogen alpha, OIII, and SII filters, Meade LX90 guided mount.
DescriptionNGC7380 is an open cluster in the star-forming diffuse nebula Sh2-142. Located in the constellation Cepheus, the nebula is estimated to be 7,200 light years from earth. Sulphur II, hydrogen-alpha, and oxygen III filters mapped to Red, Green, and Blue channels (Hubble palette). 4 hours total exposure.

EquipmentEquipment list: C-11 scope Older G-11 mount (totally rebuilt and tuned by me) with FS2 goto and ESCAP steppers TCF-s focuser Optec 0.5 reducer ST2000XM with 2020 imaging chip and 237 guide chip CFW8 with A-Don LRGB I series and 13nm Astronimik Ha All housed within my Black River Observatory near Port Huron, Michigan
DescriptionThis is my rendition of M-81, also know as Bode's Nebula. I spent 3 nights collecting data for this image during a week-long clear spell. This is a beautiful and relatively close spiral galaxy. Look closely and you can see that something has disrupted one of the spiral arms. It appears that the arm is lifted away from the galactic plane. Perhaps it was an interaction with it's neighbor, M-82?
